SCSI Peripheral Cable

Turbo Cache Issue

CTRL-ALT-DELETE Anomaly


SCSI Peripheral Cable

March 1992

BACKGROUND ON ISSUE:

Initial Professional Workstation plans called for the SCSI internal drive cable and the SCSI terminal connector to be shipped with each 4F configuation.  Subsequent market analysis has indicated a preference for the IDE configuration.  Based on this analysis, the following changes have been made.

ISSUE:

4F configurations of the Professional Workstation will be shipped with the IDE internal drive cable.  The SCSI internal drive cable and the SCSI terminator connector will not be included in the 4F configurations even though the product guide in the shipping carton with the product indicates it is included.

WORKAROUND:

Should you have requests for the SCSI terminal connector or SCSI internal drive cable, contact the sources listed below.

SCSI terminal connector can be sourced from the following vendors:

VENDOR	PART NO.	RESOURCE
NSD (800)-468-3548	201463-001	Sourced from AMP, but may offer better price on small orders
AMP	749535-1	Some distributors already use AMP as a vendor
Foxconn		Reference AMP part number to order

SCSI internal drive cable can be sourced from the following vendors:

VENDOR	PART NUMBER
NSD	514295-001
Other	OPD has a document (514295) detailing the cable that be given to any OPD customer so that their local cable supplier can build same.  Contact your distributor for this document.


Professional Workstation Turbo Cache Issue
Turbo Cache Issue

There are two issues that may cause problems when trying to use the Intel 485 TurboCache module with the Professional Workstation.

Issue #1:

TurboCache modules with S-spec part number of SX569, SX570, SX571, & SX572 have SRAMS with a design fault that can cause a system to hang or to corrupt data in the SRAM.  The problem arose when the vendor, Micron, did a die shrink.  Parts manufactured with an S-SPEC number prior to and after those listed above do not have this design problem.

Corrective Actions:

All TurboCache modules with S-Spec Numbers of SX569, SX570, SX571, & SX572 have been purged from all locations in manufacturing, materials, and BSW.

Issue #2:

The Intel 485 TurboCache Module will fail when used with the Professional Workstation in a Novell 3.11 environment, causing a system hang or data corruption over the network.  This failure will occur in either Client or Server mode.

An analysis of the failure revealed a design problem with the TurboCache module.  When the cache module is doing a cache line fill operation from memory, it is possible for an EISA bus master device to gain control of the memory bus at the same time and change the same memory location currently in the process of being cached.  When the CPU module restarts the line fill, the TurboCache module updates the cache memories but not the tag memory, resulting in data in valid cache lines that map to the same line index being corrupted in the cache.

The problem has varying degrees of severity depending upon the configuration of the system.  The worst case is running a EISA bus master card along with software which implements semaphore passing without the LOCK prefix.  LOCKED memory operations are not cached.  Therefore if the memory read is a locked operation, the TurboCache module will not attempt to cache the memory read that results in other cached data being corrupted.

Although this problem has only been seen when running Novell 3.11, there is no guarantee that it will not happen with other Software/Hardware configurations.  Software that implements semaphore passing or any other algorithm in which the CPU module and a EISA BUS master are reading and writing common memory locations without the LOCK prefix could display this problem.

Corrective Actions:

OPD has qualified a second source for external cache modules.  We recommend using this cache instead of the 485 TurboCache module.  The new vendor is IDT (Integrated Data Technologies, 408-727-6116).  The vendor part number is IDT7MB6098S33K.  This is a 128 KB direct mapped write-through secondary cache.  This part is offered by Intel through the CACHEMOD128 order code.

See Cache Memory Feature for more details concerning the IDT cache module.


CTRL-ALT-DELETE Anomaly

PROBLEM:

Earlier Professional Workstations with BIOS 1.00 01.S0 may occasionally hang after a CNTRL-ALT-DEL keystroke sequence.

REASON:

The use of MS-DOS 5.0 in conjunction with the use of DEVICE=ANSI.SYS and LASTDRIVE=statements in the CONFIG.SYS will create an environment that can cause the system to hang on a soft reset.

RESOLUTION:

Obtain the latest FLASH BIOS Upgrade from the iPAN BBS, (503)-693-1493.  Use the following login id:  first name=guest, last name=guest, and password=guest.  (Note:  use all lower case letters.)

Initial production BIOS release.

Upgrade Disk

Part Number

469338-001

Version  1.00 02.S0	effective March, 1992

1.  Updated video BIOS with the Intel/WD interface.

2.  Change EISA chipset timing parameter to increase performance and robustness.

3.  INT 15 interface for LAN and SCSI was made bimodal.

NOTE:  This BIOS was never officially released or ECO'd into the product.

Version  1.00 03.S0	effective May, 1992

1.  Fixes INT 15 LAN interface bug.

2.  Fixed DEPCA boot problem, isolated to READ DASD TYPE function.

3.  Changed defaults on serial and parallel ports to ENABLED.

4.  Changed Drive Type 36 to support Quantum 120AT.

Version  1.00 04.S0	effective August, 1992

1.  Change Drive Type 8 to support Conner 120 MB drive.

NOTE:  Although this BIOS was never officially ECO'd into the product, several systems were shipped with this BIOS installed by mistake.

Version  1.00 05.S0	effective October, 1992

BUG FIXES:

New Western Digital Video BIOS fixes several video issues:

Snow on screen when opening a window.

CGA emulation bug.

Video RAM memory size correctly detected.

Multiple CTL-ALT-DEL soft reset bugs fixed relating to HIMEM, EMM386, ANSI.SYS, and Windows.

Correctly resets Primary CPU when OverDriveTM processor installed.

Prevents new NVRAM checksum from being generated following a reset.

Parity latch cleared before boot to latch correct address.

Serial port redirection fixed to work at 1200 BAUD.

SETUP cannot be entered without a password if Power-on Password is enabled.

The Disable Setup Entry jumper also disables the Enter Setup message.

Changed EISA defaults to report correct memory size to prevent memory managers from hanging.

SETUP clock correctly increments minutes.

Forced default values don't scramble Ethernet address.

ENHANCEMENTS:

New SETUP Parameters:

640x480 Refresh rate -	60 / 75 Hz
Scan User FLASH area -	Enable / Disable
Cache -	Enable All / Enable All except Video / Disable All
SETUP parameter "Enhanced I/O" definition changed:

Enabled - Turns on fast video cycles, speeds up DRAM timing, enables parity checking in C0000-EFFFF address range.

Disabled - Turns off fast video, disables fast DRAM timing, disables parity checking in C0000-EFFFF range.

Space key will bypass the "Enter SETUP" message.

Version  1.00 06.S0	effective January, 1993

BUG FIXES:

Fixes wrong key specified in some error messages (SPACE key vs ESC key).

Updates NVRAM with correct processor type/speed information.

Fixes CMOS corruption caused by glitch from keyboard controller.

Fixes soft reset failures with on-bd LAN installed.

ENHANCEMENTS:

Adds additional cache enable/disable selection.

Adds 640x480 72 refresh rate selection.

Adds option to disable POST gating messages (skip memory test, enter SETUP).

Upgrade Disk

Part Number

612340-001

Version  1.00 07.S0	effective April, 1993

BUG FIXES:

Fixes soft reset failures with on-bd LAN installed.  BIOS 1.00 06.S0 did not properly implement this fix.

ENHANCEMENTS:

KNOWN BUGS:

PS/2 Port timing problem:  There is a potential timing incompatibility with with some PS/2 mice and keyboards.  This timing problem will result in erratic operation of the mouse or possible incorrect characters from the keyboard.  A workaround file MOUSFX.ZIP is available on the Intel Apps BBS (916-356-3605) to correct this problem.

FLASH Recovery Process fails with DOS 6.0:  The BIOS FLASH recovery procedure will fail on a system booted with Microsoft DOS 6.0.  The recovery procedure is only used in the event the normal FLASH update procedure fails.  The only workaround for this problem is to install the recovery files on a DOS 5.0 or earlier bootable diskette.

Four 32 MB SIMMs not recognized correctly:  The BIOS will only report a total of 64 MB of memory instead of the expected 128 MB.

Introduction to the Professional Workstation
Introduction to the Professional Workstation Microcomputer

The Professional Workstation product family delivers excellent, cost effective performance in a low-profile chassis.  Incorporating SCSI, LAN, and Video controllers on the motherboard, the Professional Workstation provides a number of on-board resources that would otherwise require the use of add-in 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.  Integration tasks by the OEM are simplified, system reliability is increased, and a consistent set of functions and options are provided to the end user, improving system compatibility.  A range of price/performance options is provided by offering a choice of 4 different i486-based CPUs.  A performance upgrade socket allows for easy processor upgrades in the field.  Additionally, two EISA compatible expansion slots deliver high performance expandibility.

The Professional Workstation will excel in networked business workstation and CAD/CAM applications, in office automation applications requiring multi-function client systems, and as a high performance integrated PC platform.

This document outlines the features and specifications for the Intel Professional Workstation Microcomputer product line.  A basic understanding of the Professional Workstation will be provided by detailing the features, capabilities, and benefits of the product.  Detailed technical information is provided in the appendices for those users who would like to know more about how to interface additional hardware with the Professional Workstation.

Professional Workstation Memory Features
Memory Features

The Professional Workstation provides four 36-bit wide SIMM sites for memory expansion.  The memory array is controlled by an Intel 82359 DRAM controller, data buffering is provided by two Intel 82353 Advanced Data Path devices.  The four SIMM sites support 256K x 36, 512K x 36, 1M x 36, and 2M x 36 SIMM modules, and will support 16M x 36 and 32M x 36 modules as they become available.  Maximum current memory size, using four 2M x 36 SIMM modules is 32 MBytes.  Memory timing is designed for 80 ns fast page devices, faster DRAMs will operate in the board but will provide no performance improvement.  Parity generation/checking is provided for each 8-bit byte. Systems initially shipped by Intel had two 2 MByte SIMMs installed.  The current configuration is one 4 MByte SIMM.

SIMMs may be installed in combinations of one, two, or four modules and each SIMM must be of the same memory size.  These restrictions allow the memory design to be optimized for the best possible performance.  The best memory performance is achieved when all four SIMM sites are populated.  This allows for 4-way interleaving of the DRAM, supporting n-1-1-1 type burst cycles from the i486.  If only two SIMMs are present the DRAM will be 2-way interleaved.  The slowest memory accesses occur when only one SIMM site is populated.

There are no jumper settings required for the memory size configuration, the System BIOS automatically sizes memory and initializes the 82359 DRAM controller for appropriate DRAM configuration and interleave factor.

See also System Memory Menu for additional information.


Professional Workstation LAN Controller Features
LAN  Subsystem

  82596CA LAN Controller

The on-board LAN controller is an Intel 82596CA operating at 33MHz and is IEEE 802.3 compliant.  The controller resides on the Buffered bus of the 82358DT EISA Bus Controller (for more information on the Buffered Bus, see the 82358DT data sheet).  The 82596CA shares memory space in main memory with the i486 processor.  A 64-byte transmit FIFO and a 128-byte receive FIFO is contained in the 82596CA.  When the transmit FIFO reaches a predetermined threshold level, network transmission begins.  When the receive FIFO reaches its threshold level, the 82596CA arbitrates for control of the Buffered Bus and transfers the contents of the FIFO into main memory.

  Ethernet Address

Each system has its own unique 6-byte Ethernet address as specified by the IEEE 802.3 standard.  This address is stored in the FLASH EPROM on the system board.  The Ethernet address area in FLASH memory is write protected to prevent accidental erasure.  Software can access this address via a BIOS INT15 call, the user can display both the ethernet address and the interrupt being used by the 82596CA from the System Information screen accessed via the SETUP program.

  LAN Media Connections

The Professional Workstation supports both the Attachment Unit Interface (AUI) and Twisted Pair (10BaseT) network connections.  Only one interface can be active at any one time, and only one cable should be connected to the Professional Workstation at any one time to prevent possible loading issues on the inactive interface.  The active interface is selectable via the SETUP program.

AUI is specified in Chapter 7 of the IEEE 802.3 Ethernet specification.  Connection is via a 15-pin D-sub connector located on the back panel of the system.  The AUI connection provides a 12 V source, a one amp fuse on the motherboard provides overcurrent protection.  An external Medium Attachment Unit (MAU) may be connected to interface to other network mediums, such as Cheapernet (10Base2).

10BaseT is specified in the IEEE 802.3 supplement, Section 14.  Connection to the LAN is via an RJ-45 connector located on the back panel of the system.

  LAN Drivers

DOS LAN drivers are included in the Base Software Kit which is shipped with the system.  Three protocols are supported, IPX and ODI for Novell and NDIS for Microsoft compatible networks.  Microsoft compatible networks include Microsoft LANMAN, BANYAN Vines, DEC Pathworks, and IBM LAN server.

See the Software Driver Menu for more detailed driver information


Cache Features
Cache Memory Features

In addition to the i486's internal cache, the Professional Workstation provides a socket for an optional external cache, the IDT7MB6098S33K Cache Module from Intetgrated Data Technologies.  The socket allows two additional price/performance configurations:  no external cache, or 128 KByte cache.  Presence of the cache module is automatically detected, no software or hardware changes are required to take advantage of the external cache.  The external cache is enabled/disabled in conjunction with the internal i486 cache, both are either on or off together.

The module implements a direct mapped, write-through secondary cache architecture, and provides full burst mode support for the i486.  Cache accesses occur at zero wait states.  There is also an option in the BIOS Setup program allowing selected memory addresses to be designated as non-cacheable.

Notes:  Due to an errata on the 82359 DRAM Controller, the external cache module will not work correctly with only one SIMM installed.  A label has been attached to the socket to warn users of this potential limitation. This errata will be corrected in the next stepping of the 82359, expected in late Q2 92.


Central Processing Unit(CPU) Features

The Professional Workstation allows for a choice of different i486-based CPUs:  the LP486SX/20E uses a 20 MHz i486SX, the LP486SX/25E uses a 25 MHz i486SX, the LP486DX/33E uses a 33 MHz i486DX, and the LP486DX2/50 uses a 25 MHz i486DX2. The i486DX2/50 embodies the latest "clock doubling" technology from Intel.  This component has been created with an internal clock that runs twice as fast as the external clock, i.e. the i486DX2/50 still runs @ 25 MHz but the internals of the CPU run at 50 Mhz.  The wide range in system performance that this engenders allows the OEM to select the price/performance option appropriate for his application.

The Professional Workstation supports all the i486 CPU functionality.  Common features of the CPUs include backward compatibility with the 8086, 80286,  and 386 CPUs, burst mode bus cycles, and an on-chip 8 Kbyte cache.  The cache is 4-way set associative and uses a write-through policy.  The cache can be disabled via either software or hardware.  The i486DX CPUs contain an on-chip numeric coprocessor to increase the speed of floating point operations.  This coprocessor is backward code compatible with 387DX and 387SX math coprocessors and complies to ANSI/IEEE standard 754-1985.


OverDrive Processor (ODP) Socket
OverDrive Processor Socket

 A socket is provided that allows users to upgrade the CPU performance of their systems.  An i486SX based Professional Workstation can be upgraded in two ways:  by installing an i487SX component in the OverDrive socket or by adding an OverDrive processor.  This improves system performance by either adding a numeric coprocessor to speed floating point calculations or by increasing the maximum internal CPU speed capability.  The upgrade path for i486DX based systems also takes the OverDrive processor path although the numeric coprocessor is not an option.  The Table below shows the choices of upgrade processors available.  There is a Jumper block (J10) on the motherboard that allows for OverDrive CPU speed selection.

OverDrive Processor Supported	Jumpers?
ODP486SX-20 ODP486SX-25 ODP486SX-33 ODP486DX-33	J10:11-13, 12-14 J10:10-12, 11-13 J10:9-11, 12-14 J10:9-11, 12-14


Battery and Real Time Clock Features

The Real Time Clock (RTC) is implemented using a Dallas DS1287 device.  The DS1287 is accurate to within 13 minutes/year and requires no external support (the battery and oscillator are integrated into the device).  The component is socketed and can be replaced if the internal battery loses its charge (the internal battery has an estimated lifetime of ten years).

The RTC can be set via the BIOS SETUP Program.  CMOS memory supports the standard 64-byte battery-backed RAM, fourteen bytes for clock and control registers, fifty 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.


Speaker Port

The onboard speaker has been integrated into the power supply to improve manufacturability and reduce unnecessary cabling.  The speaker may be enabled or disabled using the BIOS SETUP program and may also be programmed using I/O port 61H.  The speaker provides error code information during POST if the system cannot use the video interface.


Phoenix Technologies BIOS Features

The system BIOS is stored in two Intel FLASH EEPROM (28F001BT) devices, providing a total of 256 KByte of program code space via a paged ROM memory scheme.  The Professional Workstation uses Phoenix Technologies 80486 ROM BIOS PLUS.  In addition to the Phoenix BIOS, the FLASH memory also contains the SETUP utility, Power-On Self-Tests (POST), video BIOS, SCSI BIOS, Ethernet address, EISA configuration memory, EISA board ID, an 8-KByte user definable region, and update recovery code.  For improved system performance, the Professional Workstation supports system BIOS shadowing, allowing the BIOS to execute from 32-bit on-board write-protected DRAM instead of the slower 8-bit FLASH devices.

The increased functionality of the BIOS required more memory space than the standard 128 KByte region reserved for system BIOS.  A unique page ROM memory scheme (patent pending) was implemented to include the enhanced functionality while ensuring compatibility with standard PC architecture.  Not all the ROM is accessible at once, page registers control which two 64 KByte pages are available at any one time.  During normal operation, the 64 KByte page at E0000-EFFFF always contains the video BIOS, while the 64 KByte page located at F0000-FFFFF swaps between one of three pages:  POST, SETUP, and run-time BIOS.

Further information on BIOS functions can be found in the documents listed below:

·	IBM PS/2 and Personal Computer BIOS Technical Reference.

·	CBIOS for IBM PS/2 Computers and Compatibles.

·	ABIOS for IBM PS/2 Computers and Compatibles.

The first document is published by IBM and the second and third documents are part of the Phoenix Technologies' Technical Reference Series and are available at most technical bookstores.

1.  BIOS Upgrades

FLASH memory brings new opportunities for distributing BIOS upgrades.  Installing a new version of BIOS will no longer require removal of the system cover and the replacement of EPROM'S.  Instead, the upgrade can be done completely from a floppy diskette.  Easy access to BIOS upgrades will be available through down-loadable files on the iPAN bulletin board.Security is provided in two ways.  First, the FLASH upgrade utility insures the upgrade BIOS matches the target system to prevent accidentally installing a BIOS for a different type of system.  Second, security to prevent unauthorized changes to the BIOS is provided via a write protect jumper on the motherboard.  The default setting is to allow BIOS upgrades.  A recovery jumper is provided to recover from the unlikely event of an unsuccessful BIOS upgrade.  It forces the ROM decode to access an 16 KByte block of write protected code in the FLASH device that facilitates recovery.  The default value for this jumper is for "normal" mode (note:  this jumper is not changed during normal BIOS updates, it is used only if a problem is encountered).

2.  BIOS Setup Program

The BIOS SETUP Program has been enhanced and provides several new options to take advantage of the Professional Workstation's new features.  New options include:

On-board LAN -- enable/disable

On-board SCSI -- enable/disable.

Lan Media type -- Twisted pair or AUI.

On-board IDE -- enable/disable

800x600 Mode Refresh Rate -- 56/60/72Hz.  Allows the user to set the refresh rate appropriate to his monitor to obtain the sharpest display.

1024x768 Mode Refresh Rate -- Interlaced @ 44-88Hz / Non-interlaced @ 60Hz / Non-interlaced @ 70Hz/ Non-interlaced @ 72Hz.  Allows the user to set the refresh rate appropriate to his monitor (less expensive interlaced or high resolution non-interlaced) to obtain the sharpest display.

On-board Mouse Port -- Enable/Disable.  Disabling the mouse port frees up an interrupt line.

Parallel Port -- Enable/Disable, Bi-directional/Output only, LPT1/LPT2.

Cache Block Disable -- Enable/Disable.  When enabled, allows specified blocks of memory to be designated as non-cacheable.

I/O Bus Performance -- Standard/Enhanced.  Changes the refresh timing characteristics of the system to enhance performance.  The system will enable a function called FAST VIDEO  if this setup parameter is ENABLED. This will improve the video performance by a factor of approximately 2. Expansion cards that make use of the bus refresh signal may not work correctly with this parameter set to enhanced mode.

Shadow Memory Options -- Allows specified 16 KByte blocks of memory from C0000 to DFFFFH to be shadowed to on-board DRAM.  Primarily used to shadow expansion card ROM.

System Information -- Displays information on several aspects of system configuration, such as Ethernet address, BIOS version, processor type, LAN media type, etc.

The SETUP program is accessed by pushing the F1 key following a reboot of the system.  For security purposes, access to SETUP can disabled via a jumper on the motherboard.


Phoenix Technologies Keyboard Controller Features

An Intel 8742 surface mount micro controller contains the Phoenix Technologies PS/2 compatible keyboard/mouse controller code.  PS/2 style keyboard and mouse connectors are located on backpanel of the system.  The micro controller code supports Power-On/Reset (POR), network, and keyboard password protection.  Network and keyboard passwords require programs contained on the utility disk that ships with the system, the POR password is set via the SETUP program.   In addition, the keyboard controller 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, excluding memory tests.

·	CTRL-ALT-1 and CTRL-ALT-2:	Turbo mode selection*.

These two sequences can be used to toggle between turbo and de-turbo modes. CTRLALT1 sets the system into de-turbo mode (emulates an MHz 80286 CPU using wait states) and CTRLALT2 sets the system into turbo mode (its normal operation at 33MHz).

·	CTRL-ALT-+ and CTRL-ALT--:  Keystroke Click Sound level selection.

This adjusts the speaker level for the click sounds made when a key is depressed.  The level of sound may be adjusted from not audible to loud with 7 levels in between.

*Note:  Changing the Turbo mode may at times be prohibited by an operating system or application software.


EISA Bus Interface

The interface to the EISA bus is controlled by the Intel 82350DT chip set.  The chip set consists of a 82358DT EISA Bus Controller (EBC), a 82357 Integrated System Peripheral (ISP), a 82359 DRAM controller, two 82353 Advanced Data Path buffers, and two 82352 EISA Bus Buffers (EBB) (one in data buffer mode, the other in address buffer mode).

1.  82359 DRAM Controller

The 82359 provides all control signals necessary to drive the DRAM array, including multiplexed address signals.  It also controls system access to memory and generates snoop controls to maintain cache coherency.

2.  82358DT EISA Bus Controller (EBC)

The 82358DT is a superset of the original 82358 and includes a mode compatible with the 82359 Buffered Bus.  The EBC controls all EISA bus cycles, including DMA transfers, EISA and ISA bus master cycles, and Host EISA cycles.  The EBC also controls any byte swapping and byte assembly required.

3.  82357 Integrated System Peripheral (ISP)

The 82357 integrates seven 32-bit DMA channels, five 16-bit timer/counters, two eight-channel interrupt controllers, NMI logic, refresh address generation, and EISA bus arbitration circuitry together onto the same device.

4.  82353 Advanced Data Path (ADP)

The two 82353 ADPs provide data paths between the Host Bus, the DRAM array, and the system interface.  Each ADP provides 16-bits of host data, one for even bytes, one for odd bytes.  Both the Host and system interfaces are 32-bits wide, the interface to the memory array is 128-bits wide.

  82352 EISA Bus Buffer (EBB)

The 82352 EBBs provide address and data buffering to the EISA bus.  One EBB is used for address buffering, the second EBB is used to buffer the 32 data bits.


EISA Expansion Slots

The Professional Workstation motherboard contains one EISA compatible connector.  This connector is used to support a riser card that contains two horizontal EISA bus master expansion slots.  These expansion slots support 8- or 16-bit ISA compatible expansions cards as well as any EISA compatible expansion cards.  The EISA expansion cards are oriented parallel to the motherboard, rather than perpendicular.  This parallel orientation makes the low profile chassis outline possible.  The riser card is limited to a maximum of two EISA expansion slots by electrical constraints of the motherboard as well as physical constraints of the system chassis.


Power Supply Features
Power Supply

The Professional Workstation uses a custom power supply with auto-ranging AC input and an approximate total power output of 142 watts.  The power supply is a totally self-contained module that connects directly to the motherboard via a custom connector, eliminating all power cables in the system.  In addition to the normal power supply circuitry, the module also houses the on/off and reset switches, front panel LED's, the speaker, external AC receptacles, and thermostatically controlled cooling fans.  All minimum load requirements for the power supply are met by the minimum configuration motherboard.

A female auxiliary AC power outlet is provided at the rear of the system so that, with the right adapter, the system monitor can be plugged into the Professional Workstation.  This simplifies the power-on sequence by turning the monitor on or off with the base system.  The voltage output from the auxiliary power connector corresponds to the system's input AC voltage

The onboard speaker has been integrated into the power supply to improve manufacturability and reduce unnecessary cabling.  The speaker may be enabled or disabled using the BIOS SETUP program and may also be programmed using I/O port 61H.  The speaker provides error code information during POST if the system cannot use the video interface.


Peripheral Bays
System Peripherals

1.  Peripheral Bays

The Professional Workstation supports 2 built-in peripheral bays in a single peripheral carrier assembly.  The bays included are:

·	1- Half-Height, 3.5" wide, Internal bay

Mounting hardware supports standard 3.5" hard disk drives form factor.

Connections for either SCSI or IDE.

·	1- Third-Height, 3.5" wide, Externally accessible bay

Connection for custom "docking" 3.5" floppy drive (see Floppy Drive Interface below).

The carrier assembly is easily removed for access and serviceability.  A riser card is used to route the control, data and power signals for the floppy and hard drive from the motherboard to the peripheral carrier.  The peripheral riser card connects to the motherboard via a 132-pin card-edge connector and is attached to the peripheral carrier by two mounting brackets.  Internal SCSI termination resistors are always present on the peripheral riser card.

2.  Floppy Drive Interface

An on-board AT compatible floppy interface is provided by an Intel 82077AA-1 Floppy Controller.  The Professional Workstation supports only a single 3.5" 1.44 MByte floppy drive.  The drive uses a custom docking connector, allowing the drive to connect directly to the peripheral riser card.  This eliminates the need for power and data cables, improving reliability, serviceability and EMI characteristics.  The floppy drive can be enabled or disabled via the BIOS SETUP program.  An option for increased security disables writes to the floppy drive via a jumper on the motherboard.

3.  Mass Storage Devices

The Professional Workstation supports one internal 3.5" half height mass storage device using either the SCSI-2 or standard 40-pin IDE interface.  Cable length is reduced to a minimum by using a peripheral riser card to route the control and power signals up to the drive bay.  This improves the serviceability and reduces EMI emissions.  The hard disk drive can be enabled or disabled via the BIOS SETUP program.  Selection between the SCSI or IDE interface is also done via SETUP.


Professional Workstation Front Panel
Front Panel

The front panel includes the reset and power-on/off switches for easy access.  Hard Disk active, floppy active, and power-on LED indicators are also provided.  All the LED indicators are green.


Professional Workstation Chassis Features
Chassis Features

The Professional Workstation is housed in a low profile chassis.  The enclosure consists of a sheet metal base, sheet metal top cover, and drop-in peripheral carrier.  There are four color keyed plastic pieces:  the front bezel and top/side cover snap onto the metal top cover, the back panel and bottom snap onto the sheet metal base.  Access to the inside of the system is obtained by removing one screw and lifting off the top cover.


Professional Workstation Security Features
Security

1.  Physical Security

A standard hasp style lock (not provided by Intel) can be used to retain the top cover.  This prevents undesired access to the internal compartment of the Professional Workstation where the CMOS Password Clear jumper is located.  In addition, it prevents someone from removing or modifying add-in cards or peripherals.  The hasp lock can also be used to cable the Professional Workstation to a fixed object, preventing theft of the system.

2.  Network Security

The Professional Workstation was designed with several features to make it an especially secure system in a network environment.  A CMOS-based password during Power-on/Reset can be enabled.  If the password jumper is set to "keep" and a valid password has been entered from the BIOS SETUP program, the system will prompt for a password every time the system is rebooted.  The system will prompt for a password until the password is cleared at power-up or the password jumper is moved to "clear".  The password can be cleared or changed when the system prompts for the password by following the steps below:

1)	To remove a password at the "Enter password:" prompt type the current password followed by a forward slash character. Example, "Enter password: current_password/<cr>", will remove the current password.

2)	To change a password at the "Enter password:" prompt, type current password, forward slash, new password, forward slash, new password, carriage return. Example, "Enter Password: current_password/new_password/new_password<cr>".

Other security features include a jumper to disable access to the BIOS SETUP program to prevent unauthorized modifications, and a jumper to disable the floppy write capability to prevent downloading of proprietary software or confidential data.


SCSI Subsystem

1.  NCR 53C700 SCSI I/O Processor (SIOP)

The on-board SCSI I/O processor is a NCR 53C700.  This component has internal FIFOs on the SCSI and host data busses, 32-bit address and data busses, and an internal SCRIPTS processor capable of fast DMA.  A custom ASIC is used to convert the 386-like bus interface of the NCR 53C700 to the asynchronous strobed interface required by the 82359 DRAM Controller.  The SIOP runs at 33 MHz, the maximum theoretical data transfer rate is 66 MBytes/sec across the Buffered Bus, and 8.25 MBytes/sec across the SCSI bus.

2.  SCSI Physical Interface

The SCSI Physical Interface consists of the SCSI connector for the internal hard drive, the external SCSI port, the terminations at each end of the SCSI bus, and the SCSI termination power circuitry.

A riser card is used to connect the baseboard SCSI bus to the SCSI hard drive.  The Power Workstation supports only the single ended SCSI mode.  A short ribbon cable with standard 3M type connectors and power cable are used to connect the drive to the riser card.

A fine pitch 50-pin connector located on the back panel of the system is used for the external SCSI interface.  When an internal SCSI drive is installed, up to six additional SCSI devices can be connected via the external connector.  This number can be increased to seven when no internal SCSI drive is installed.

The SCSI standard requires termination at each end of the bus.  Termination for the internal drive is soldered into the riser card.  Therefore, internal drives must not have termination resistors installed.  Termination at the external end of the bus consists of an external removable termination block. This termination block is available from both AMP and FOXCON. The AMP part number is 749535-2. This terminator is not required when an internal IDE drive is implemented. Termination power is routed to the termination resistors through a 1.0 Amp fuse.  Termination power can be disabled via a jumper on the motherboard for applications where a different SCSI device is supplying termination power.

3.  SCSI Drivers

SCSI drivers for DOS are shipped with the system.  No drivers are required for DOS if Protected Mode of the CPU is not used, i.e. memory mangers or Windows 3.0/3.1 is NOT  used, and the only peripheral devices installed are one or two SCSI hard disks using the onboard SCSI controller: All functions are taken care of by the SCSI BIOS.  All other situations, such as multiple host adapters, mixture of SCSI and IDE drives, booting from a SCSI device other than a hard drive, use of an extended memory manager (such as QEMM, EMM386 or Windows 3.0), etc., require installation of the (4) supplied SCSI drivers.

See the Software Driver Menu for more detailed driver information


Video Subsystem

1.  Western Digital WD90C30/C31 Graphics Controller

The Professional Workstation incorporates an Extended VGA video solution onto the system board using a Western Digital WD90C30/C31 chip-set.  Intel's patent pending circuitry can speed graphics performance by up to 50% over standard designs.  The WD90C30/C31 is fully compatible with the MDA, CGA, Hercules Graphics, EGA, and VGA video standards.  Standard configuration comes with 1 MByte of installed video DRAM.  This allows for resolutions up to 1024 x 768 x 256 colors..  (Systems built before May, 1992 were shipped with 512 KBytes of video memory.  The video memory can be increased to a total of 1 MByte by adding four 256K x 4 fast page mode 60 ns DRAMs to the four DIP sockets on the system board.)  The Professional Workstation supports non-interlaced as well as interlaced monitors even at the higher resolutions.  The Display Ram is paged into 128 KBytes of RAM located between A0000H and BFFFFH.

2.  Western Digital Video BIOS

Video BIOS from Western Digital 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 video modes.  To allow for the use of other add-in video adapter cards, the on-board video BIOS can be disabled using a hardware jumper.

3.  Video Connectors

A standard PS/2 15-pin analog VGA connector is provided on the I/O backpanel.  A VESA compliant 8514/A Feature Connector is provided on the baseboard.  This is typically used as a VGA pass through connector when an auxiliary video subsystem is installed in one of the expansion slots, such as an 8514/A compatible video card or DVI board set.

4.  Video Drivers and Utilities

Video drivers and utilities for DOS and WINDOWS 3.0/3.1 are shipped with the Professional Workstation system.  Included on the diskettes are enhanced mode drivers for common MS-DOS software applications such as AutoCAD, AutoShade, Cadvance, Framework, GEM, Generic Cadd, PCAD, VersaCAD, WordPerfect, WordStar, Ventura and Lotus 123 & Symphony.  These come in a compressed form and are extracted by using a utility called "install" located on the diskette.  Several video utilities such as a screen saver and VGA mode switch routine are also included with the drivers.  Video drivers for SCO UNIX should be obtained from the respective UNIX distributor.

See the Software Driver Menu for more detailed driver information


EISA Configuration Utility (ECU)
EISA Configuration Utility

An EISA Configuration Utility (ECU) is shipped with the system.  The ECU performs the setup and programming of the system's EISA Non-Volatile Memory (NVM).  A section of FLASH memory is used to store the EISA configuration information.  EISA and ISA boards are added and removed with the ECU to complete the specific system configuration.  The configuration is stored into FLASH memory and the system is rebooted.  The contents of the EISA NVM and ISA CMOS memory are used by system BIOS at boot time to configure EISA boards and determine system policies.  Refer to the information contained in the ECU HELP facility for more information.

See the Software Driver Menu for more detailed driver information


Western Digital Serial Controller
Western Digital WD16C552 Serial/Parallel Controller

The Professional Workstation uses a WD16C552 compatible device to integrate one parallel and two serial ports on the motherboard.  Standard AT-type connectors are available on the back panel of the system.  The serial ports include 16-byte FIFOs and are capable of operation up to 56 KBaud.  Either serial port can be programmed as COM1, COM2, COM3, COM4, or disabled.

Notes:

·	Above 512 Kbyte Baseboard memory, Video BIOS aliasing, and SCSI can be enabled/disabled via SETUP.

·	The option of re-mapping the video BIOS to 0C-0000H is provided for applications that require the video BIOS at that location.  If you are not sure if that your application requires the video BIOS to be located at 0C-0000H (most do not) then do not enable this option in SETUP.  Not enabling video mapping to 0C-0000H saves 32K of memory.  In any case, the on-board video BIOS will always be located at 0E-0000H.

·	The BIOS SETUP program provides for shadowing off-board ROM BIOS into onboard RAM on 16K boundaries.  This is available in memory located between 0C0000H and 0DFFFFH.

*	Under certain circumstances these areas of memory may be included into the memory pool used by a memory manager i.e EMM386

**	The memory consumed by the SCSI BIOS is only 20K bytes long but the system will shadow a 32KByte range of memory due to the granularity of the hardware shadowing system.. With the SCSI BIOS installed the area from 0CD000 to 0CFFFF cannot be used for add-in boards but can be used by a memory manager i.e EMM386. The memory manager will include this area by default.

***	Inclusion of this area into the memory  pool of  a memory manager like EMM386 may cause malfunction in the use of both onboard networking and SCSI devices and off board EISA add-in boards.
