Viper VLB OS/2 2.1 Driver Release Notes Version 1.1
Driver Version 1.0


Assumptions:
These drivers assume that normal VGA video drivers are currently installed.  
Please make sure that the VGA video drivers are installed for the primary 
video adapter.


**********************************IMPORTANT**********************************
Before selecting a driver, make sure that your monitor can support the refresh
rate of the driver you want to use.  If you select a refresh rate that your 
monitor does not support, you can damage the monitor.  Diamond Computer
Systems is not responsible for any damage incurred by incorrect selection of
refresh rates.
**********************************IMPORTANT**********************************


Installation: 
Before installing the drivers, copy the following files to a backup directory 
or floppy, as they will be modified:

\CONFIG.SYS
\OS2\OS2.INI
\OS2\MDOS\WINOS2\SYSTEM.INI

To install the drivers:
1.  Insert the Viper OS/2 2.1 driver disk 1 into a diskette drive.
2.  Select an OS/2 Windows or OS/2 Full Screen session from the Command 
    Prompts folder.
3.  Type A: or B: (depending on where the Viper OS/2 driver disk 1 is located) 
    and press Enter.
4.  Type DSPINSTL and hit Enter.
5.  Click on the OK button on the Help not Available dialog box.
6.  Select the Primary Display check-box, then click OK.
7.  Select the desired resolution, color depth, and refresh rate combination 
    from the list-box, then click OK.
8.  Type in the correct path to the driver disk, then click OK.
9.  The file will be copied to the appropriate directories, and the necessary 
    configuration files will be modified.
10.  If prompted, insert the Viper OS/2 2.1 driver disk 2 and click on OK.
11.  When installation is complete, select Cancel.
12.  You will then see a dialog box indicating that changes have been made 
     to your system configuration.  Click on OK.
13.  Exit the OS/2 Windows or OS/2 Full Screen command prompt by typing EXIT 
     and then pressing Enter.
14.  Shut down the system and restart OS/2.  Remember to remove the driver 
     disk from your floppy drive.


Notes:
Support for the secondary video adapter is not currently available.  If you 
select the secondary adapter, no files will be copied, and configuration files 
will be modified.

This release supports OS/2 version 2.1 or better.  It requires the 32-bit 
graphics engine.  Do not attempt to install these drivers on OS/2 version 2.0.

During the installation, if the DSPINSTL program cannot find the driver disk, 
the volume labels may not have been correctly extracted.  The correct volume 
labels are P90DRV 1 (the space between P90DRV and the 1 is required) for the 
first disk and P90DRV 2 (the space between P90DRV and the 2 is required) for 
the second disk.  For example, if your drive A is your 3.5" floppy drive, and
you are trying to label the first disk, you would type:
LABEL A: <enter>
P90DRV 1 <enter>

If your system hangs after installation, or the mouse pointer does not appear, 
then make sure that the statement DEVICE=\OS2\POWER_9K\P9000.SYS is placed at 
the top of the CONFIG.SYS file.

To return to standard VGA after installing the Viper OS/2 2.1 drivers:
1.  Insert the Viper OS/2 2.1 driver disk into a diskette drive.
2.  Select an OS/2 Windows or OS/2 Full Screen session from the Command 
    Prompts folder.
3.  Type A: or B: (depending on where the Viper OS/2 driver disk is located) 
    and press Enter.
4.  Type DSPINSTL and hit Enter.
5.  Click on the OK button (or hit Enter) on the Help not Available dialog 
    box.
6.  Select the Primary Display check-box, then click OK.
7.  Select the Remove P9000 Driver option, then click OK.
8.  Change the location of the source driver (if necessary), then click OK.
9.  When the system reports the completion, remove the driver diskette, shut 
    down your system and reboot.
