This changing of the motherboard involved the stepping of three different pieces of the system:

1.  The Neptune Chipset (PCMC/LBX) stepped from A0 to A1.

2.  The SMC665 stepped from D to GT.

This fixes many of the bugs related to COMM port useage.

3.  The BIOS stepped from 1.00.04.BF0 to 1.00.06.BF0

This version of the BIOS is the new PHASE II Bios that supports Power Management, Plug and Play, and has a new friendlier interface.

Password Changes

Beta 4.01

o	Both User and Administrative passwords are available.

o	Passwords have been extended to seven(7) characters instead of the current six(6).


Language Support

Beta 4.01

o	Multi-language support is now available.

o	OEMs and users will be able to flash language sets into the BIOS and configure which language is used through Setup.  The current plas is for language pairs consisting of: English(US)/German(GR), English(US)/Italian(IT), English(US)/French(FR), and English(US)/Spanish(SP).

o	Depending upon the size of the FLASH device used for a particular product, up to 32 languages may be present at one time in the BIOS.


Hard Disk Changes

Beta 4.01

o	User definable parameters are available on a per drive basis.  This means each of the four drives may have unique user defined parameters.

o	The DMA selection (Auto-Configured or Disabled) may be set on a per drive basis.  (The ability to select the DMA transfer mode has been removed.)

o	The Sector/Block selection (Auto-Configured, 8 Sectors/Block, 4 Sectors/Block, or Disabled) for multiple sector transfers may be set on a per drive basis.  (The ability for finer resolution of Sector/Block size has been removed.)

o	The ability to disable fast PIO modes has been added.  This selection (Auto-Configured or Disabled) may be set on a per drive basis.

o	The Translation selection (Auto-Configured, Logical Block Addressing, Extended Cylinder/Head/Sector or Standard Cylinder/Head/Sector) may be set on a per drive basis.

o	A Hard Disk Pre-Delay has been added to the Boot Options screen.  This option sets a fixed amount of time to wait in POST before attempting to initialize any of the hard disks.  This delay occurs only once before calling the hard disk initialization code.  Because POST is so fast on this version of BIOS, many drives have not finished their power on self-test routines by the time the BIOS reaches its hard disk initialization code.  For certain drives, if the BIOS attempts to query the drive before it has finished its self-test, the drive may hang.  In an attempt to accommodate a user with one of these drives this option has been made available.  (This option is available on some current products.)


Chicago Plug and Play

Beta 4.01

o	Plug and Play version 1.2 will be supported in the Phase II BIOS.

o	Setup menus are still TBD.


APM 1.1

Beta 4.01

o	Advanced Power Management that supports both the APM 1.0 and 1.1 specifications.

o	Standby and Suspend are handled as like events allowing power down from OS/2 Control Panel.

o	Critical 1.1 calls are allowed even if the OS connects as 1.0.  This allows POWER.EXE to run in 1.0 while a custom Windows driver takes advantage of full 1.1 compatibility.

o	Setup menus are still TBD.


New Int 15h Extensions

Beta 4.01

o	New Int 15h Extensions for Extended Memory and Memory Map have been added.

o	Function E801 has been added to report the amount of contiguous memory above 1Mb.

o	Function E820 has been added to report a full memory map of the system.  This function is used by Chicago and newer versions of Windows NT.


Other Changes

Beta 4.01

o	A setup field has been added to enable/disable the Guaranteed Access Time (GAT) Mode for ISA Master and DMA devices.  This feature may enhance the performance of ISA Master and DMA devices while degrading the performance of other non-ISA based devices.  Disabling this feature may improve sound quality on some ISA based sound cards.

o	A setup field has been added to enable/disable Byte Merging on PCI.  This feature enhances performance but may break some PCI graphics cards.


Known Errata With This Release

o	When NUM LOCK is enabled at boot, the number '4' will appear at the DOS prompt after boot.  This only happens on a cold boot, and may disappear if you reboot a system that has already warmed up.


BIOS 1.00.04.BF0

This BIOS was created to fix a bug in the A0 stepping of the Neptune Chipset that caused errors when the PCI bus bursts to memory.  BIOS 1.00.04.BF0 turns off this feature in the Neptune A0 chipset, which fixes the problem.  The system level performance impact was estimated at less than 1%.

Known problems with this BIOS (that are fixed in future releases):

1.  Predelay and timeout default settings may miss IDE hard drive on cold boot.

2.  Auto and Manual Configuration of the I/O sent conflicting messages to CMOS.


BIOS 1.00.03.BF0

This was the initial BIOS release.

Known problems with this BIOS (that are fixed in future releases):

1.  Predelay and timeout default settings may miss IDE hard drive on cold boot.

2.  Some SCSI problems were seen on boot up.

3.  Auto and Manual Configuration of the I/O sent conflicting messages to CMOS.

Approved SIMM List

The following tables list SIMMs that are known to be compatible with the Classic E. SIMMs that are not listed also should function properly as long as their specifications are compatible with the devices listed below. In general, SIMM devices that are faster than those specified for a given platform will work although no extra performance will be realized.  The SIMM devices shown are categorized according to three levels of qualification:

1. Intel Approved and Tested:  The device has been electrically tested by Intel and is known to be compatible with the Classic E. In addition, the vendor has met or exceeded Intel's product change, quality control, and availability requirements and is listed on our Approved Manufacturing List.

2. Intel Tested: The device has been electrically tested by Intel across voltage and temperature margins ("four corners") and is known to be compatible with the specified platform(s).

3. Customer Tested: The device has been electrically tested by a customer and is reported to be compatible with the specified platform(s).

Intel recommends that SIMMs listed as (1) Intel Approved and Tested or (2) Intel Tested be used to ensure reliable system operation. SIMMs not listed or listed as (3) Customer Tested can be used; but, in the event of unreliable system operation, the SIMMs should be replaced with SIMMs tested by Intel (1 or 2) to determine whether the SIMMs are causing the problem.

IMPORTANT NOTE

SIMM devices with gold contacts should NOT be placed into SIMM sockets with tin-lead contacts or vice-versa. Mixing dissimilar metal contact types has been shown to result in unreliable memory operation. For more information, see FaxBack document 4229.

Telphone numbers are provided for your convenience.  These were accurate as of March 1994, but may change at any time without notice.

Functional Considerations

VGA FEATURE CONNECTOR AND VRAM BASED MACH64 PRODUCTS

The 64-bit architecture of ATI Mach64 based products, consist of a complete 64-bit internal data path with a high-end RAMDAC and VRAM.  This configuration allows the RAMDAC to read directly from the VRAM to the screen when operating in accelerator mode.  This architecture makes it possible to deliver high performance, high resolution, high color depth and high refresh rate for todays advanced platforms.   The Display drivers developed for the 64-bit architecture are written to operate in accelerator mode and to utilize the full capablities of the architecture.

The VGA Feature Connector intercepts the standard VGA pixel bus that exists between the graphics controller and the RAMDAC.  This is in keeping with the original VGA feature connector specification.  The Mach64 display drivers use the entire 64-bit path that exists between the RAMDAC and the VRAM, and results in the VGA pixel bus being bypassed. When this occurs, any device attached to the feature connector (Capture Cards, Overlay products, etc) will not receive display information.  This will cause conditions of "no display" or "black windows".

This is a multifold issue, and to ATI's knowledge, the limitation of the VGA feature connector, the 64 bit architecture, accelerated 64-bit Windows Drivers and VRAM based Memory Configurations will occur with most all 64-bit Graphics Products.   However, the VGA Feature Connector on ATI mach64 VRAM products will operate satisfactorily in the Windows environment, in VGA Mode, by using the MS supplied VGA Windows Drivers (Non-Accelerated Drivers).

The VESA feature connector issue only occurs on mach64 VRAM based adapters, preliminary testing shows that mach64 DRAM based adapters will indeed function correctly with video-capture cards that use the VESA feature connector.


3rd Party Issues

PC Tools and 90MHz Pentium

PC Tools versions 7.1, 8.0, and 9.0 will not run on a 90MHz machine with the cache enabled.  Currently Intel is in contact with Central Point to resolve this issue.  PC Tools will run with the cache disabled through setup.


Known Errata

POST HASTE BIOS

A problem has been discovered with some IDE hard drives being missed by the Post Haste BIOS version 1.00.04.BF0 and all previous BIOS releases.  The default hard drive timeout is five seconds, which does not allow some hard drives to spin up on a cold boot.  The error is non-system disk, or missing operating system.  In setup, edit the timeout from five to 10 seconds as well as changing the predelay from disabled to 3 seconds.


Technical Product Summary - Introduction
Introduction

The Premiere/PCI GX delivers excellent, cost-effective performance in a low-profile form factor using the Pentium processor at iCOMP index 735\90 MHz. The baseboard is a highly integrated design, that offers outstanding I/O capabilities from a high performance primary IDE interface on the PCI local bus and a Super I/O component that provides floppy drive and secondary IDE interfaces, two FIFO serial ports and an ECP-capable parallel port. The Pentium processor 735\90 is complemented by a 256 KB second level write-back cache to provide workstation-level computing performance. A Type 5 socket provides access to future performance enhancements using Pentium OverDrive processors, and SIMM sockets support up to 128 MB of DRAM.

Because of the high level of integration, the Premiere/PCI GX provides a number of on-board resources that otherwise would require the use of expensive I/O expansion cards. This integration delivers increased functionality, increased reliability, and increased performance while reducing the system power requirements and the need for a large number of expansion slots. The OEM's integration tasks are simplified, system reliability is increased, and a consistent set of functions and options are provided to the user, improving system compatibility.

The Premiere/PCI GX will excel as an entry-level Pentium processor desktop delivering the latest in CPU and I/O technology, while also opening up new markets with its workstation level performance.

CPU

The Premiere/PCI GX baseboard is designed to operate with the Pentium processor 735\90. This processor has an internal speed of 90 MHz and an external speed of 60 MHz and is backward-compatible with the 8086, 80286, i386 and Intel486 processors. The Pentium processor 735\90 supports both read and write burst mode bus cycles, and includes separate 8 KB on-chip code and data caches which employ a write-back policy. Also integrated into the processor is an advanced numeric coprocessor which significantly increases the speed of floating point operations, while maintaining backward compatibility with i486DX math coprocessor and complying to ANSI/IEEE standard 754-1985.

Based on 0.6 micron processes, the Pentium Processor 735\90 is driven by 3.3 volts (as opposed to 5 volts) and supports Intel's SMM power-management operation. A patented on-board voltage regulator circuit provides the required 3.3 volts from the 12 volts provided by a standard PC power supply.


Performance Upgrades

A 320-pin Type 5 Zero Insertion Force socket provides users with an OverDrive processor upgrade path. An upgrade processor being developed for use with this socket will provide performance beyond that delivered by the Pentium Processor 735\90.


Second Level Cache

The Pentium processor's internal cache is complemented with a 256 KB direct mapped, write-back second level cache implemented with eight 32Kx8, 15ns SRAM devices. Tag and control logic is contained in the 82434NX, PCMC (Neptune) chip.


Technical Product Summary - Board Level Features - System Memory
System Memory

ThePremier/PCI GX motherboard provides four 72-pin SIMM sites for memory expansion. The sockets (one 90° angled and three 40° angled) support 256K x 36 (1 MB), 512K x 36 (2 MB), 1M x 36 (4 MB), 2M x 36 (8 MB), 4M x 36 (16 MB), and 8M x 36 (32 MB) SIMMs. The minimum memory size is 2 MB and the maximum memory size, using four 8M x 36 SIMMs, is 128 MB. Memory timing requires 70 ns fast page devices. Parity generation/checking is provided for each byte. The parity generation/checking circuitry can be disabled to allow for use of non-parity 32 bit SIMMs.

The four sockets are arranged as Bank 0 and Bank 1, with each bank consisting of two sockets and providing a 64-bit wide data path. Both SIMMs in a bank must be of the same memory size and type, although Banks 0 and 1 may have different types of memory installed (i.e.: parity or non-parity). Bank 0 only, Bank 1 only, or both banks may be populated. There are no jumper settings required for the memory size, which is automatically detected by the system BIOS. Tin-lead SIMMs should be used when adding DRAM.

The memory array is controlled by the Intel 82434NX PCMC and data buffering is provided by two Intel 82433NX Local Bus Extension devices.


PCI Riser Slot

The Premiere/PCI GX baseboard contains one custom connector. This connector supports a riser card that can contain ISA bus expansion slots, up to two PCI expansion slots, or combination slots. The expansion cards are oriented parallel to the baseboard, rather than perpendicular. This parallel orientation makes possible a low profile chassis outline. The riser card is limited to a maximum of two PCI expansion slots because signals are available to support only two PCI masters. The connector is identical to those used in an EISA system: ISA signals are directed to the standard ISA positions, and PCI signals are available via the deep finger method.

PCI 3.3 Volt Capabilities


PCI 3.3 Volt Capabilities

To maintain strict compliance with the PCI specification, the baseboard provides an unpopulated site which can be used for a connector to route 3.3 volt power to the PCI slots. The 3.3 volt power must be provided by a separate 3.3 volt power supply or a custom designed voltage converter. Please note that the on-board 3.3 volt regulator provides power only for the Pentium processor and not the PCI slots.


Peripheral Component Interconnect (PCI) Chip Set

The Intel Neptune chip set consists of one 82434NX PCI/Cache/Memory Controller (PCMC), two 82433NX Local Bus eXtension (LBX) devices, and one 82378ZB System I/O (SIO.G) bridge chip. The Neptune chip set provides the following functions:

• CPU reset control

• CPU L1 cache control

• CPU burst mode control

• CPU interface control

• Integrated second level write-back cache controller with tag comparator

•Fast Page-mode DRAM controller

• Burst memory read/write control logic

82434NX PCI/Cache/Memory Controller (PCMC)

The 82434NX provides all control signals necessary to drive a second level cache and the DRAM array, including multiplexed address signals. It also controls system access to memory and generates snoop controls to maintain cache coherency.


82433NX Local Bus eXtension (LBX)

There are two 82433NX components which provide data bus buffering and dual port buffering to the memory array. Controlled by the 82434NX, the 82433NX devices add one load each to the PCI bus and perform all the necessary byte and word swapping required. Memory and I/O write buffers are included in these devices.


82378ZB System I/O (SIO.G)

The 82378ZB integrates seven 32-bit DMA channels, five 16-bit timer/counters, two eight-channel interrupt controllers, PCI-to-AT interrupt mapping circuitry, NMI logic, ISA refresh address generation, and PCI/ISA bus arbitration circuitry together onto the same device.

Detailed information on the chip set is available in the Intel 82430 PCISet data sheet.

Graphics Drivers and Utilities


ATI 88800GX Graphics Controller

The Premier PCI GX motherboard incorporates an Extended VGA graphics solution onto the system board using an ATI 88800GX connected directly to the PCI bus. The ATI 88800GX is fully compatible with the MDA, CGA, Hercules Graphics, EGA, and VGA graphics standards. The standard configuration comes with 2 MB of installed graphics VRAM allowing for resolutions up to 1280 x 1024 by 64K (16 bit) colors. The graphics subsystem supports non-interlaced as well as interlaced monitors and the display RAM is paged into 128 KB of system RAM located between A0000H and BFFFFH.


ATI Graphics BIOS

The graphics BIOS from ATI has been incorporated into the system BIOS. The BIOS supports the normal VGA modes (0,1,2,3,4,5,6,7,D,E,F,10,11,12,13) and also supports several enhanced graphics modes (See Appendix I for the complete list). To allow for the use of other addin graphics adapter cards, the system BIOS will detect the presence of the add-in card graphics BIOS and automatically disable the on-board graphics controller and BIOS.


Graphics Connectors

A standard PS/2 15pin analog VGA connector is provided on the system back panel. A VESA compliant 8514/A feature connector is located on the baseboard. The 8514/A interface typically is used as a VGA pass-through when an auxiliary video subsystem is installed in one of the expansion slots, such as the Intel Smart Video Recorder™ video capture board.


Graphics Drivers and Utilities

Graphics drivers and utilities for DOS and Windows 3.1 are shipped with the Premier PCI GX. These drivers come in a compressed form and are extracted by using an installation utility provided on the diskette. The graphics drivers for Windows 3.1 include a utility called "SetRES" which allows the user to change the screen resolution, number of colors, and large or small fonts while in Windows. After the new options have been selected, the user can choose to immediately restart Windows or have the new options take place the next time Windows is started.

Graphics drivers for common MS-DOS software applications such as AutoCAD, AutoDesk, AutoShade, AutoSketch, GEM/3, Lotus 123, Microsoft Word, WordPerfect, WordStar, and Ventura Publisher are included on the drivers diskette. Drivers for SCO and Interactive UNIX should be obtained from the respective UNIX vendor. Graphics drivers also are available for downloading from iPAN, the electronic bulletin board service of IntelTechDirect™. This and other support services are listed in Appendix M.


SMC 37C665 Super I/O Controller

Control for the integrated serial ports, parallel port, floppy drive and IDE hard drive interface is incorporated into a single component, the SMC 37C665. This component provides:

•	Two NS16C552-compatible UARTs with send/receive 16 byte FIFO

•	Multi-mode bi-directional parallel port

- Standard mode; IBM and Centronics compatible

- Enhanced Parallel Port (EPP) with BIOS/Driver support

- High Speed mode; Enhanced Capabilities Port (ECP) compatible

•	Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)

•	IDE hard disk decode and chip select

Standard DIN connectors are available at the back of the board. The serial ports can be enabled as COM1 and COM2, or disabled. The parallel port can be configured via the SETUP program as LPT1 or disabled, and can be set as bi-directional or output only when enabled. The IDE interface supports Compatible, Type B, and Type F DMA.


PCI Local Bus IDE Subsystem

The Premiere/PCI GX baseboard offers two IDE channels: one on the PCI local bus and one on the ISA bus. PCI-based IDE provides performance much improved over the traditional ISA-based IDE.

Related Topics:

PCI TO IDE INTERFACE CIRCUIT

IDE PHYSICAL INTERFACE


PCI TO IDE INTERFACE CIRCUIT

The onboard PCI to IDE interface is provided by the PCTech RZ1000, which is fully compatible with existing IDE software. No special drivers are required. Performance is enhanced with fully programmable IDE interface timing, including command pulse width and cycle time. BIOS support is included in the onboard system BIOS. The BIOS initializes the RZ1000, detects any IDE drive connected to the chip, and programs registers in the RZ1000 to operate the drive at its optimal bandwidth. All transfers to the drive after that time, whether using BIOS calls or direct, operate at the programmed timings.


IDE PHYSICAL INTERFACE

The PCI IDE physical interface consists of a dedicated 40-pin header connector. The other 40-pin connector is dedicated to the ISA IDE interface. PCI is the primary IDE interface and ISA is the secondary interface.


Keyboard and Mouse Interface

An Intel 8242 surface mount microcontroller contains the Phoenix Technologies-based PS/2*-compatible keyboard/mouse controller code. The PS/2-style keyboard and mouse connectors are located on the back panel side of the baseboard. The 5V line on these connectors are protected with a PolySwitch* circuit which acts much like a self-healing fuse, re-establishing the connection after an over-current condition is removed. While this device eliminates the possibility of having to replace a fuse, care should be taken to turn off the system power before installing or removing a keyboard.

The 8242 microcontroller code supports Power-On/Reset (POR) password protection. The POR password is set via the Setup program. The keyboard controller also provides for the following "hot key" sequences:

•	<CTRL><ALT><DEL>: System software reset. This sequence performs a software reset of the system by jumping to the beginning of the BIOS code and running the POST operation.

•	<CTRL><ALT><+> and <CTRL><ALT><->: Turbo mode selection. <CTRL><ALT><-> sets the system for de-turbo mode and <CTRL><ALT><+> sets the system for turbo mode (normal operation). Changing the turbo mode may be prohibited by an operating system or application software.


Dallas DS12887 Real Time Clock, CMOS RAM and Battery

The Real Time Clock (RTC) is implemented using a Dallas DS12887 device. The DS12887 is accurate to within 13 minutes/year and requires no external support. The oscillator and battery are integrated into the device and the estimated life-span of the battery is 10 years.

The RTC can be set via the BIOS SETUP Program. CMOS memory supports the standard 128byte batterybacked RAM, fourteen bytes for clock and control registers, and 114 bytes of general purpose non-volatile CMOS RAM. All CMOS RAM is reserved for BIOS use. The CMOS RAM can be set to specific values or cleared to the system default values using the BIOS SETUP program. Also, the CMOS RAM values can be cleared to the system defaults by using a hardware jumper. Appendix B lists jumper configurations.


System BIOS

The Premiere/PCI GX baseboard uses an American Megatrends Incorporated (AMI) ROM BIOS, which is stored in Flash EEPROM and easily upgraded using a floppy disk-based program. BIOS upgrades will be downloadable from the Intel bulletin board system. In addition to the AMIBIOS, the Flash EEPROM also contains the Setup utility, Power-On Self Tests (POST), update recovery code, video BIOS, and the PCI auto-configuration utility. This baseboard supports system BIOS shadowing, allowing the BIOS to execute from 32-bit on-board write-protected DRAM.

The BIOS displays a sign-on message during POST identifying the type of BIOS and a five-digit revision code. First production units will display a revision code of 1.00.01.BF0. As BIOS updates occur, the revision number will increase to 1.00.02.BF0, and so on.

Information on BIOS functions can be found in the IBM PS/2 and Personal Computer BIOS Technical Reference published by IBM, and the ISA and EISA Hi-Flex AMIBIOS Technical Reference published by AMI. Both manuals are available at most technical bookstores.

FLASH Implementation

The Intel 28F001BXT 1 Mb FLASH component is organized as 128K x 8 (128 KB). The Flash device is divided into five areas, as described in Table 1.

System Address		FLASH Memory Area
F0000H	FFFFFH	64 KB Main BIOS
EE000H	EFFFFH	8 KB Boot Block (Not FLASH erasable)
ED000H	EDFFFH	LOGO Reserved
E8000H	ECFFFH	20 KB System BIOS Reserved
E0000H	E7FFFH	Graphics BIOS (relocated to C0000-C7FFF at boot, available as upper memory)
Table 1. Flash memory organization

The FLASH device resides in system memory in two 64 KB segments starting at E0000H, and can be mapped two different ways, depending on the mode of operation. In Normal Mode, address line A16 is inverted, setting the E000H and F000H segments so that the BIOS is organized as shown in the system address column above. Recovery mode removes the inversion on address line A16, swapping the E000H and F000H segments so that the 8 KB boot block resides at FE000H where the CPU expects the bootstrap loader to exist. This mode is only necessary in the unlikely event that a BIOS upgrade procedure is interrupted, causing the BIOS to be left in an unusable state. For information on recovering the BIOS in the event of catastrophic failure, refer to Appendix F.


BIOS Upgrades

FLASH memory makes distributing BIOS upgrades easy. A new version of the BIOS can be installed from a diskette. BIOS upgrades will be available as downloadable files on the iPAN bulletin board.

The disk-based Flash upgrade utility (FMUP.EXE) has three options for BIOS upgrades:

• 	The Flash BIOS can be updated from a file on a disk;

• 	The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the event that an upgrade cannot be successfully completed; or

• 	The BIOS in the Flash device can be compared with a disk file to ensure the system has the correct BIOS version.

The upgrade utility ensures the upgrade BIOS matches the target system to prevent accidentally installing a BIOS for a different type of system. Security to prevent unauthorized changes to the BIOS is provided via a write-protect jumper on the baseboard. The default setting is to allow BIOS upgrades. A recovery jumper is provided to allow recovery in the unlikely event of an unsuccessful BIOS upgrade. The jumper forces the ROM decode to access a 8 KB block of write protected recovery code in the Flash device.


Setup Utility

The ROM-based Setup utility allows the configuration to be modified without opening the system for most basic changes. The Premiere/PCI GX baseboard also incorporates many new capabilities into the Flash EEPROM, including:

•	Auto configuration of IDE hard disks (manual selection of the drive type is no longer required).

•	Support for two IDE disk interfaces (primary and secondary) providing access to 4 IDE devices.

•	An option allowing the user to assign a block of addresses below the 1 MB boundary as non-shadowed, non-cached. This area is primarily used for expansion card ROM which causes timing problems when shadowed and cached.

•	ISA interrupts IRQ9, IRQ10 and IRQ11 may be set to used and assigned to add-in ISA adapters, thereby informing the PCI configuration utility that these interrupts are not available for PCI cards.

The Setup utility is accessible only during the Power-On Self Test (POST) by pressing the <DEL> or <F1> key after the POST memory test has begun and before boot begins. A prompt may be enabled that informs users to press the <F1> key to access Setup. A baseboard jumper can be set to prevent user access to Setup for security purposes. Setup options are detailed in Appendix D.


PCI Auto-configuration Capability

The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow the insertion and removal of PCI cards without user intervention. When the system is turned on after adding a PCI add-in card, the BIOS automatically configures interrupts, DMA channels, I/O space, and other parameters. The user does not have to configure jumpers or worry about potential resource conflicts. Because PCI cards use the same interrupt resources as ISA cards, the user must specify the interrupts used by ISA add-in cards in the Setup utility. The PCI Auto-Configuration function complies with version 2.0g of the PCI BIOS specification.


ISA Plug & Play Capability

The BIOS will incorporate ISA Plug and Play capabilities as delivered by Intel Architecture Labs Plug and Play Release 1.2. This will allow auto-configuration of Plug and Play ISA cards, and of older non-Plug and Play ISA cards, when used in conjunction with the ISA Configuration Utility. Information about the IAL Plug and Play specification may be obtained via FaxBack (800-628-2283) or via CompuServe (Go PlugPlay).


Power Management Capability

The Premiere/PCI LC baseboard supports power management via System Management Mode (SMM) interrupts to the CPU and Advanced Power Management (APM) BIOS support. In general, power management capabilities will allow the system to be put into a power-managed state when the user enters a hot-key combination, or when a hardware timer detects the system has been inactive for a user-specified amount of time. While in a power-managed state, the baseboard will be capable of reducing CPU power consumption and informing the disk drive and graphics controllers to also invoke power management. Power management capabilities are still being defined. Please refer to APM specification version 1.1 for further details.


Security features


BIOS Password

A BIOS password feature provides security during the boot process. A password can be entered using the Setup utility and must be re-entered prior to disk boot each time the system is reset. To enable, disable, or change the password, refer to the Setup program options in Appendix D.

If the password is forgotten, it can be cleared by turning off the system and setting the "password clear" jumper to the clear position.


Setup Enable Jumper

A baseboard jumper controls access to the BIOS Setup utility. By setting jumper to the disable position, the user is prevented from accessing the Setup utility at any time.

Chassis

A slimline case gives the Premiere/PCI GX Low Profile Desktop a sleek look − while four peripheral bays, two PCI slots, and three ISA slots offer the expandability required for traditional PC applications. A 145 watt power supply ensures the system can support installation of the maximum number of peripherals and add-in cards. The Premiere/PCI GX also has been tested to ensure it meets stringent environmental requirements.


Peripheral Bays

Four peripheral bays offer ample expandability for add-in devices. The system provides two 5¼" half-height bays, one 3½" one-inch bay, and one 3½" 1.6-inch bay. Both 5¼" bays and one of the 3.5" bays are accessible from the front panel. The final 3½" hard drive bay is internal. The two 5¼" bays also can accommodate a single 5¼" full-height drive.

Figure 4. Premiere/PCI GX peripheral bays


Fan

The Premiere/PCI GX has two fans to keep the system cool. One fan within the power supply provides 28 CFM of air movement. The second fan, located behind the card guide, provides 26 CFM across the add-in cards and the CPU. The second fan receives 12 Vdc directly from the baseboard at connector location .


Front Panel

The front panel provides access to the system power switch. A power-on LED and a hard disk access LED provide visual system information. The front panel also provides access to three peripheral bays (two 5¼" and one 3½"), as described above.

Figure 5. Premiere/PCI GX front bezel


Expansion slots

The Premiere/PCI GX has five expansion card slots as shown in Figure 6. One slot is a full length 16-bit ISA card slot, two are half length 16-bit ISA card slots, one is a full length PCI slot, and one is a half length PCI slot. The Premiere/PCI GX riser card uses a custom edge connector to route PCI signals from the baseboard.


Back panel

The back panel consists of access covers for the expansion slots, two DB9 RS-232 serial ports, a bi-directional parallel port, PS/2-style keyboard and mouse connectors, a video output connector, a 115/230 voltage switch, a power supply input, an auxiliary power output and the power supply fan.

Figure 6. Premiere/PCI GX back panel.


Power Supply

A 145 watt switchable power supply (maximum power dissipation: 120w) is integrated into the Premiere/PCI GX Desktop to provide power for onboard resources, add-in cards, and peripherals. A switch on the back of the system sets the Astec 3430 power supply to operate at either 90-132VAC (5 Amps AC) or 180-264 VAC (3 Amps AC). The auxiliary AC power outlet is rated at 2A maximum for 100-120V and 1A maximum for 200-240V.

Technical Product Summary - Setup Overview - Introduction
Introduction

This User's Guide documents the "Phase II" BIOS Setup Utility.  It explains the overall organization of the utility, how to navigate through the utility, and individual fields and options.

The "Phase II" BIOS Setup Utility is divided into 4 major menus:

Main Menu

Advanced Menu

Security Menu

Exit Menu

Each of the major menus occupy the left and center sections of the computer screen.  Selecting certain fields within the major menus will drop the user into sub-menus.  Displayed on the right side of the screen  is a Command Screen which describes the commands used to interact with the Setup Utility.  The following section documents these commands.  The subsequent four sections describe each of the main menus.  Sub-menus are documented within the main menus from which they are invoked   In each section the field which is being displayed is bold type.  If there are user selectable options for that field they are displayed in italic  type.  Explanations and comments about the fields and options are contained within boxes.


Command Screen Navigation

The right side of the Setup screen contains a list of  commands which are available to the user as they navigate through and interact with the Setup Utility.  These commands are displayed at all times, for each menu and sub-menu.

F1	Help

Help is provided for a subset of the fields.  It can not be invoked when parameter options are being displayed.

ESC	Back

The ESC key provides a mechanism for backing out of any field.  When the ESC key is entered from the top level of any field, the field options cease to be displayed.  When the ESC key is entered from the top level of any sub-menu, the parent menu is re-entered.  When the ESC key is entered from the top level of any major menu the following screen is displayed:

Exit Discarding Changes

Press Enter to Continue

Press ESC to Abort

At this point pressing the Enter key will cause the user to leave the Setup Utility without saving any changes they might have made.  Pressing the ESC key will  bring them back to the top level of the current menu.

Enter	Select

The Enter key is used to activate sub-menus, change parameters and select parameter options.

Previous Item

The up arrow is used to move to the menu item above the current item.  It does not wrap around.

Next Item

The down arrow is used to move to the menu item below the current item.  It does not wrap around.

Select Menu

The left and right arrow keys are used to move between the 4 major menus. They do not wrap around.

F5	Setup Defaults

The Setup Defaults key is used to set all Setup Parameters to their default values.  When this key is pressed the following message appears:

Load Setup Defaults?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then all Setup Parameters will be set to their default values.  If the ESC key is selected, then the user is returned to where they were before F5 was pressed without effecting any change.

F6	Previous Values

The Previous Values key is used to set all Setup Parameters to their previous values.  When this key is pressed the following message appears:

Discard Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then all Setup Parameters will be return to the values selected when Setup was entered.  If the ESC key is selected, then the user is returned to where they were before F6 was pressed without effecting any change.

F10	Save & Exit

The Save & Exit key is used to exit the Setup Utility saving the current state of all parameters   When this key is pressed the following message appears:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to where they were before F10 was pressed without effecting any change.

Main Menu Navigation

Each menu  contains a number of parameters.  Most parameters can be changed by the user, although some are informative only.  Parameters which can be changed by the user are displayed in black, informative only parameters are displayed in blue.  Depending on the security option chosen and in effect (via password), a parameter can be either changeable or non-changeable.  A parameter which is non changeable due to insufficient security privilege or other reasons will be grayed out.  Parameters which have no effect based on the value other parameters are not displayed.


Main Menu

System Date

Month-Day-Year

The System Date field specifies the current date .

System Time

Hour:Minute:Second

The System Time  field specifies the current time.

Floppy A:

Floppy B:

Disabled

360 Kb, 5.25 "

1.2 Mb, 5.25"

720Kb, 3.5"

1.44 Mb, 3.5"

2.88 Mb, 3.5"

The Floppy A: Type and Floppy B: Type fields specify the physical size and maximum supported media size of the floppy drives attached to the floppy interface.

Hard Disk C:

Hard Disk D: ....

Identification string returned from drive

Not Installed

The Hard Disk C: through Hard Disk F: fields report the presence of, and identification string reported by, up to 4 physical IDE drives (two each of PCI and ISA.  When the cursor is placed on one of these fields and it is selected by hitting the Enter Key, the Hard Disk Sub-Menu appears (see below) allowing parameters which affect the drives to be set.

Disk drive assignments

When drives have multiple partitions on them, partitions beyond the primary partition will be assigned in ascending order, based on available drive letters and other installed drives.  Partitions are assigned to primary partitions first (across multiple drives), and then to secondary partitions.  This means that when there are multiple drives with multiple partitions, the logical drive numbering scheme may result in discontiguous logical partitions on the same physical drive.

For instance, if there is a "Drive 1" with two partitions which is a Master on the PCI IDE interface, a "Drive 2" with three partitions which is a Slave on the PCI interface, and a "Drive 3" with two partitions which is a master on the ISA interface the drive letters will be assigned as follows:

Drive 1	Primary Partition	C:

Secondary Partition	F:

Drive 2	Primary Partition	D:

Secondary Partition	G:

Tertiary Partition	H:

Drive 3	Primary Partition	E:

Secondary Partition	I:

Hard Disk Sub-Menu

Hard Disk Type

Auto Configured -- default

User Definable

Number of Cylinders

Number of Heads

Number of Sectors

If	Hard Disk Type = Auto Configured

Then parameters reported by drive

If	Hard Disk Type = User Definable

Then parameters entered by user

The Number of Cylinders, Number of Heads, and Number of Sectors  fields display what is reported by the drive if Hard Disk Type is set to Auto Configured.  If Hard Disk Type is set to User Definable then these fields are entered by the user. Hard Disk Type should be set to Auto Configured unless the drive was formatted on another system with parameters different than those reported by the drive.

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled

5 Seconds

10 Seconds -- default

31 Seconds

Initialization Timeout selects the number of seconds the BIOS will wait to determine if an IDE drive is present, after initiating a transaction with the drive.  If a drive is present and responds to the BIOS before the Initialization Timeout period, then the BIOS will proceed, i.e. there is no boot-time penalty for a large value when a drive is present.  If a drive is not present, then the BIOS will wait the Initialization Timeout period before proceeding.  If a drive is present, but does not respond to the BIOS within the Initialization Timeout range, then the BIOS will not see the drive and it will not be accessible.  This value should be set to Disabled for any IDE drives not installed.  This parameter works in conjunction with the Hard Disk Pre-Delay parameter contained in the Boot Options sub-menu of the Main menu.

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used.

Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive used.

Logical Block mode overcomes the 528 MB maximum size limitation imposed by Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528 MB maximum size limitation imposed by Standard CHS mode.   It can be used with drives which are larger than 528 MB, but do not support LBA mode.

Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block  mode if it is supported by the drive. The second choice is to utilize Extended CHS   mode if the drive topology allows.  If neither of the above two methods are possible, then Standard CHS mode is used.   Important NOTE: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive.  If a drive is run in a mode other than the mode in which  it was partitioned and formatted, unpredictable results may occur, including data loss.

Different operating systems have different abilities regarding IDE Translation Modes:

UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in its own way.

OS/2 2.1 can support LBA, ECHS or Standard CHS methods . Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. (*)

OS/2 2.0 & Novell Netware can support either ECHS or Standard CHS methods, but not LBA.

DOS & Windows can support LBA, ECHS or Standard CHS methods. If the "Fast 32-bit IDE" option of Windows is utilized, make sure to use the  Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports these advanced geometrys.  You will get better performance NOT using "Fast 32-bit IDE" if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes.

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

The Multiple Sector Setting  field controls the number of sectors which are transferred by an IDE drive per interrupt generated.  If set to Disabled, then an interrupt will be generated for each sector transferred, even if the OS issues a multi-sector transfer.  If set to 4 Sectors/Block or 8 Sectors/Block then 4 or 8 sectors will be transferred per interrupt (for a request that is as large as, or larger than 4 or 8 sectors).  If Auto Detected is chosen, then x sectors will be transferred per interrupt, where x is the maximum value supported by the drive.  If a drive does not support multiple sectors/block then the BIOS will ignore this setting.  If the drive does not support the specific number (4 or 8) of sectors chosen, then the BIOS will default to the largest number of sectors smaller than the chosen value supported by the drive.

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

The Fast Programmed I/O Modes field controls the speed in which Programmed I/O (PIO) transfers occur on the PCI IDE interface.  If set to Disabled, transfers occur at an un-optimized (Mode 0) speed.  If set to Auto Detected, transfers occur at the rate which the drive reports as its maximum (up to and including the maximum mode 3 timing).  This field should only be set to Disabled if a drive is being used which incorrectly reports an ability to function with advanced timings.

Language

English (US)

..

..

The Language field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.

Boot Options

When the cursor is placed the Boot Options field and it is selected by hitting the Enter Key, the Boot Options Sub-Menu appears allowing parameters which affect the boot process to be set.

Boot Options Sub-Menu

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

The field controls the order in which the BIOS attempts to boot from the hard and floppy drives.

System Cache

Disabled

Enabled -- default

The System Cache field controls both the primary and secondary caches. Setting System Cache Disabled to will hurt performance, but might be required when running software which utilizes software timing loops and needs to be slowed down to execute properly.

Boot Speed

Turbo -- default

De-turbo

The Boot Speed field controls the system CPU cycles.  De-turbo mode slows the CPU by disabling system cache and adding increased refresh cycles.  It does not reduce CPU speed to 4.77Mhz or 8Mhz AT class machines.

Num Lock

Off -- default

On

The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system is booted.

Setup Prompt

Disabled

Enabled -- default

The Setup Prompt field controls whether the "Press <F1> Key To Enter Setup" message is displayed during POST (Power On Self Test).It does not control access, just the message.

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

The Hard Disk Pre-Delay provides a mechanism which delays the BIOS's attempt to initialize the first  IDE drive in the system.  It is necessary because certain drives take longer than others to "spin up" and might hang if they are accessed too soon after being powered up or reset.  The delay is only honored for the first drive accessed. This parameter works in conjunction with the Initialization Timeout parameter contained in the Hard Disk Sub-menu of the Main menu.  The two are added together.

It should be noted that this new addition to the BIOS Setup is the result of our speeding up the POST process.

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 15.  If Override is chosen the following two screens appear allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

The Typematic Rate Delay field controls how long it takes for the keyboard auto-repeat function to start when a keyboard key is held down.

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

24 char/sec

30 char/sec

The Typematic Rate Delay field controls the speed characters repeat when you hold down a keyboard key.  The higher the number, the faster the repeat.

Video Mode

The Video Mode  field is informative only.

Mouse

The Mouse  field is informative only.  If the system supports a PS/2 style mouse, and the mouse is installed, this field will be displayed.  If the system does not support a PS/2 style mouse, or if it does and the mouse is not installed, this field will not be displayed.

Base Memory

This Base Memory field is informative only.   There is another Base Memory field which can be changed in the Advanced Chipset Configuration Sub-Menu of the Advanced menu.

Extended Memory

The Extended Memory field is informative only. Amount of system memory above 1 Megabyte


Advanced Menu

Processor Type

Processor Speed

Cache Size

The Processor Type, Processor Speed, and Cache Size fields are informative only and can not be changed by the user. Cache Size refers to the L2 cache only.

Peripheral Configuration

Plug and Play Configuration

The Peripheral Configuration, Advanced Chipset Configuration, Power Management, and Plug and Play Configuration fields are used to enter sub-menus where these areas are configured.  Press Enter to access.

Peripheral Configuration Sub-Menu

Configuration Mode

 	Auto -- default

Manual

The Configuration Mode fields controls whether  on board resources are manually or automatically set up.  When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 6 fields (PCI IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

PCI IDE Interface

 	Enabled -- default

Disabled

Standard ISA IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

The PCI IDE Interface, Standard IDE Interface, and Floppy Interface  fields allow these drive interfaces to be individually enabled or disabled.

Serial Port 1 Address

Disabled

COM1, 3F8h -- default

COM2, 2F8h

COM3, 3E8h

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

The Serial Port 1 Address, Serial Port 2 Address fields allow the user to select the I/O ports used by these interfaces.  If a COM port is chosen for one of the Serial Port Addresses, it will not appear in the option list for the other Serial Port Address, i.e. if one of the Serial Port Addresses is set to Disabled, then there will be four choices for the other serial port address.  Otherwise there will be three choices.

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

The Parallel Port Address fields allow the user to select the I/O ports used by these interfaces.

Parallel Port Mode

Compatible -- default

Extended

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT.  When set to Extended the parallel port will be set up in the most advanced mode allowed by the chipset (ex. ECC, ECP).

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

The Serial Port 1 IRQ, , Serial Port 2 IRQ and Parallel Port IRQ  fields display the interrupts used by the Serial and Parallel Ports.  These values may not be changed by the user.  If an interface is disabled via the Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address fields, then the associated interrupt is not displayed, and is available for use by add in cards.

Advanced Chipset Configuration Sub-Menu

Base Memory Size

512KB

640 KB -- default

The Base Memory Size field controls the mapping of addresses between 512K and 640K (80000h-9FFFFh).  If 512KB is chosen then accesses between 512K and 640K are directed to the ISA bus.  When 640 KB is selected accesses between 512K and 640K are directed to system DRAM.  Unless using an ISA card which requires access to this particular address range this field should be set to 640 KB.

ISA Bus Speed

Compatible -- default

Enhanced

The ISA Bus Speed field controls the speed of the ISA Bus clock.  If set to Compatible the speed will fall within the limits defined by the IBM AT Technical Reference (6-8.33 Mhz).  If set to Enhanced the speed will be greater than the maximum defined by the IBM AT Technical Reference manual.  Modern ISA cards can operate with the enhanced speeds,  however some older cards can experience difficulties.  ISA performance will be enhanced when ISA Bus Speed is set to enhanced.   The actual value of the Bus Clock when set to Compatible or Enhanced is dependent upon the external frequency of the CPU:

External Frequency	Compatible	Enhanced

60 Mhz	7.5 Mhz	10 Mhz

66 Mhz	8.25 Mhz	11 Mhz

Byte Merging

Enabled

Disabled -- default

Byte Merging is a feature which increases performance for older applications which write to video memory in bytes instead of words.  However, this feature is not supported on all PCI video cards.  For best performance this field should be enabled unless a PCI graphics card which does not support this feature is used.  If this field is enabled and used with a card which lacks support video corruption will be seen in some video modes.

PCI IDE Prefetch Buffers

Enabled -- default

Disabled

The field is used to disable a set of prefetch buffers in the PCI IDE controller.  Disabling the buffers may be required when using Operating Systems (such as NT) which do not use the BIOS to access the hard and do not disabled interrupts when completing a programmed I/O operation.  Setting PCI IDE Prefetch Buffers to Disabled has negative performance implications.  It is anticipated that Microsoft will provide a patch which will allow the buffers to remain enabled when running NT.

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

The ISA Video Linear Frame Buffer Size provides a mechanism for creating a hole in the system memory map.  Accesses made to addresses within this hole will be directed to the ISA bus instead of main memory.  This should be set to Disabled  unless you are using an ISA card which has memory greater than 64K which needs to be accessed by the CPU,  and you are not using the Plug and Play run-time utilities (Configuration Manager & ISA Configuration Utility).

ISA LFB Base Address

Dependent upon ISA LFB Size

If	ISA LFB Size	Then	ISA  LFB Base Address

Disabled	N.A.

1 MB	15 MB

3 MB	13 MB

7 MB	9   MB

The ISA Video LFB Base Address field displays the starting address of the ISA memory hole if a value other than Disabled is chosen for the ISA Video LFB Size parameter.  If  ISA Video LFB Size is set to disabled, then this field does not appear.  This field is informative only, i.e. it cannot be changed by the user.

Video Palette Snoop

Disabled

Enabled -- default

The Video Palette Snoop field controls the ability of a PCI graphics cards to "snoop" write cycles to an ISA video card's color palette registers.   This should normally be set to Enabled.  It should only be set to Disabled  if:

An ISA card connects to a PCI graphics card via the VESA connector

AND	That ISA card connects to a color monitor

AND	That ISA card uses the RAMDAC on the PCI card

AND	The Palette Snooping feature (also called RAMDAC shadowing) is broken on the PCI card.

Latency Timer (PCI Clocks)

 	Number between 0 and 256

66 -- default

 The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus.  Its default value is 66.  In general this should not be changed.  If there are latency sensitive cards in the system (such as audio cards and/or network cards with small buffers) this can be set to a lower value to reduce latency.  If there are no latency sensitive cards in the system, but I/O intensive applications are being run, this can be increased to slightly improve performance.

 Power Management Configuration Sub-Menu

Advanced Power Management

Enabled

Disabled -- default

The Advanced Power Management  field enables or disables Advanced Power Management (APM) support in the BIOS.  If set to enabled the BIOS will work with APM aware Operating Systems to manage the power consumed by the CPU,  IDE drives, and graphics cards.  If set to Disabled then none of the other fields in the Power Management Configuration Sub-Menu are displayed.

IDE Drive Power Down

Enabled

Disabled -- default

The IDE Drive Power Down field controls whether or not a spin down command will be issued to the IDE drives when the system goes into low power mode.

VESA Video Power Down

Disabled -- default

Standby

Suspend

Sleep

The VESA Video Power Down field controls the VESA power management command issued to the graphics card when the system goes into low power mode.  The proper setting is dependent upon the VESA mode(s) supported by your  graphics card.

Inactivity Timer (Minutes)

0 to 255

0 -- default

The Inactivity Timer (Minutes) field controls the number  of  minutes that the system will detect no user activity before going into low power mode.

Hot Key

User  definable

The Hot Key field is used to define a key which when entered will cause the APM BIOS to ask an APM (Advanced Power Management) aware Operating Systems to go into immediate power managed mode.  There will be some delay, typically about a minute before the system actually goes into power managed mode,  however the speaker will issue 2 descending tones.

If there is a User Password in effect then upon going into power managed mode the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in Secure Mode.   In this case the correct password will have to be entered before the user regains control of the system.  This password will not be echoed to the screen, whether the screen is active or inactive at the time the password is entered (see Set User Password  field in Security Menu).   The following table describes how the Power Down hot key interacts with the Security Hot Key:

	Power-Down Hot Key Entered	Security Hot Key Entered
Power-Down Hot Key Only Enabled	System powers down 1 minute (can include screen blanking if enabled) Powers up when any key/mouse activity is detected	N.A.
Security Hot Key Only Enabled	N.A.	System Secure Immediately LEDs sequence Input accepted when password typed
Both Hot Keys Enabled	System Secure Immediately System powers down 1 minute (can include screen blanking if enabled) LEDs sequence Input accepted when password typed Powers up when any key/mouse activity is detected	System Secure Immediately  System powers down 1   minute (can include screen blanking if enabled) LEDs sequence Input accepted when password typed Powers up when any key/mouse activity is detected
Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

The Configuration Mode field is used to choose the method in which information about legacy ISA cards (ISA cards which do not have Plug and Play capabilities) is conveyed to the BIOS to allow the BIOS to set up PCI cards and ISA Plug and Play cards without conflicting with the legacy ISA cards.

If Use ICU is chosen, then the BIOS will depend upon information provided by run-time Plug and Play software (Configuration Manager and ISA Configuration Utility) to ensure that there are no conflicts with legacy ISA cards.  Only choose this method if your system is configured with these utilities and they are used. When Use ICU is chosen no other fields are displayed in this Sub-Menu.

If Use Setup Utility is chosen, then the BIOS will depend upon information provided by the user in the fields below to prevent conflicts between Plug and Play cards and legacy ISA cards.  If the Use Setup Utility is chosen then the user should not install and use  run-time Plug and Play software (Configuration Manager and ICU).

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

The ISA Shared Memory Size field is used to set a block of system memory which will not be shadowed (shadowing is a technique which copies a block of memory from an add in card's ROM to the same address in  system memory to allow faster access to the code and achieve higher performance).  By default all upper memory is shadowed unless a block is un-shadowed using this and the ISA Shared Memory Base Address fields.

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  64 KB is chosen, then the ISA Shared Memory Base Address field can only be set to D0000h or below.

 ISA Shared Memory Base Address

C0000h

C4000h

C8000h

CC000h

D0000h

D4000h

D8000h

DC000h

The ISA Shared Memory Base Address field works in conjunction with the ISA Shared Memory Size.  See above.

IRQ 3*

IRQ 4*

IRQ 5

IRQ 7*

IRQ 9

IRQ 10

IRQ 11

IRQ 15*

Available

Used By ISA Card

* These options will not be visible if consumed by on-board resources (IRQ3 Serial Port 1, IRQ4 Serial Port 2, IRQ7 Parallel Port, IRQ 15, both IDE interfaces used).

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.  Note: All but one can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.


Security Menu

There are two types of passwords available, User Password and Administrative Password.  The User password can be used to control access to the Setup Utility, the keyboard upon initial boot, and the keyboard when used in conjunction with the Security Hot Key.  The Administrative Password is used to control access to the Setup Utility.

If the Administrative Password is in effect and Setup is entered with the User Password only the following fields may be changed:

System Date

System Time

User Password

Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

The User Password is and Administrative Password is fields indicate whether the User and Administrative passwords have been set.  If neither the User Password is or the Administrative Password is fields are set to Enabled neither the Unattended Start or Security Hot Key (CTRL-ALT-) fields will be displayed.

Set User Password

When the Set User Password field is chosen the user is presented with one of two sub-menus.  If there is currently no User Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already a User Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Set Administrative Password

When the Set Administrative Password field is chosen the user is presented with one of two sub-menus.  If there is currently no Administrative Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already an Administrative Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Unattended Start

Disabled -- default

Enabled

The Unattended Start  field controls the point at which the User Password is required.  If set to Disabled  the User Password is required before the system boots, either from disk or the network.  The user will be prompted for the password with the text string "Enter Password (1):"

If set to Enabled the system will go through automatic boot activity (for instance running CONFIG.SYS and AUTOEXEC.BAT when booting DOS from disk), however the keyboard will be locked and the User Password must be entered to unlock it.  The BIOS does not provide any prompt string so it is suggested that the last thing that the automatic login sequence does is prompt the user for the password.

The Unattended Start field can only be set if a User Password is in effect.

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

The Security Hot Key (CTRL-ALT-) field can be used to define a key which when entered in conjunction with the CTRL and ALT keys puts the system into secure mode (locks the keyboard).  When this Hot Key combination is entered the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in secure mode (as opposed to being hung).


Exit Menu

Exit Saving Changes

The Exit Saving Changes field is used to exit the Setup Utility saving the current state of all parameters.

When the Enter key is entered the following sub-menu is displayed:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Exit Discarding Changes

The Exit Discarding Changes field is used to exit the Setup Utility discarding any changes made to Setup parameters.  When the Enter key is entered the following sub-menu is displayed:

Exit Discarding Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with changes to Setup parameters lost.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Load Setup Defaults

The Load Setup Defaults field is used to load default values into all Setup parameters, except for the passwords.  When the Enter key is entered the following sub-menu is displayed:

Load Setup Defaults?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then defaults are loaded into all Setup parameters, except for the passwords.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any changes.

Discard Changes

The Discard Changes field is used undo any changes made to Setup parameters during this Setup session.  When the Enter key is entered the following sub-menu is displayed:

Discard Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then any changes made to Setup parameters are discarded.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any changes.

Upgrades & Recovery

The Premier PCI LX Pentium P54C/PCI LPX incorporates the AMIBIOS in a Flash memory component. Flash BIOS allows easy upgrades without the need to replace an EPROM. The upgrade utility fits on a floppy diskette and provides the capability to save, verify, and update the system BIOS. The upgrade utility can be run from a hard drive or a network drive, but no memory managers can be installed during upgrades.

The latest upgrade utility and BIOS code are available in the BIOS section of the Intel bulletin board.

Related Topics:

Using The Upgrade Utility

Recovery Mode


Using The Upgrade Utility

If the utility is obtained from the bulletin board, UNZIP the archive and copy the files to a bootable MS-DOS 3.3, 4.01, 5.0, or 6.x diskette. Reboot the system with the upgrade diskette in the bootable floppy drive and follow the directions in the easy to use menu-driven program.


Recovery Mode

In the unlikely event that a FLASH upgrade is interrupted catastrophically, it is possible the BIOS may be left in an unusable state. Recovering from this condition requires the following steps (be sure a power supply and speaker have been attached to the board, and a floppy drive is connected as drive A:):

1.	Change Flash Recovery jumper (RCVR FLASH) to the recovery mode position.

2.	Install the bootable upgrade diskette into drive A:

3.	Reboot the system.

4.	Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.

5.	Turn the system off.

6.	Change the "FLASH RECOVERY" jumper back to the default position.

7.	Leave the upgrade floppy in drive A: and turn the system on.

8.	Continue with the original upgrade.
