--------------------------------------------------------------

DESCRIPTION

* Under OS/2 2.1 for Windows, an error is generated running DSPINSTL
  when trying to select the monitor, the chip set, or the resolution.

* SVGA driver installation cannot not completed.

RESOLUTION

Generate the SVGADATA.PMI file from a DOS Full Screen session by typing 
SVGA ON.

Close all sessions and applications, especially those with command 
prompts. This ensures there is no interference with driver installation 
if a driver file or DLL is being used. They become write-protected 
during the installation process. Perform the following steps.

 1. Select OS/2 System on the Desktop.

 2. Select System Setup.

 3. Select Selective Install.
 
 4. At the System Configuration screen, check Primary Display (even if
    at an SVGA resolution), and select OK.

 5. At the Primary Video Adapter screen, verify that SVGA is selected;
    then select OK.

 6. Do not make a selection at the OS/2 Setup and Installation screen;
    just select the Install push button.

 7. When prompted for the Source Directory on the next screen, indicate
    A:\ unless it needs to be the drive for the CD-ROM, or the drivers
    are loaded in another directory on the hard disk. If so, change to
    the drive and path where the drivers are stored.

 8. Select Install.

 9. When prompted, insert diskettes (normally starting with OS/2
    Installation Diskette 6 through Diskette 11. This varies depending
    on the size of the diskettes being used).

10. With the OS/2 system files updated, select Install using Default
    for Monitor; then select OK.

    The screen darkens and you are prompted to select the Video
    Resolution.

11. Highlight the desired resolution and select OK.

12. When prompted, insert Display Driver Diskette 1 in drive A; then
    select Install.

    Note: The Source Directory should be A:\.

13. Installation includes Display Driver Diskettes 1 and 2. The system
    prompts you for the correct Windows driver diskettes, based on the
    resolution you selected.

14. After completing the installation, the system prompts you to shut
    down and restart. DO NOT PERFORM SHUTDOWN.

15. Select OK.

16. Go to a DOS Full Screen session; then type CD OS2 and press Enter.

17. Type SVGA ON and press Enter.

18. Type EXIT and press Enter.

19. Shut down and then restart the system.

Notes about Installation of High-resolution Drivers
---------------------------------------------------
Different monitors and video adapters can affect the successful loading 
of drivers. Some configurations might require utility diskettes 
supplied by the video-adapter manufacturer to ensure the correct 
refresh rates are set up.

Following is a partial listing of video adapters and the utility 
programs that apply. These are all DOS-based and must be run from a 
full-screen session before loading the SVGA drivers. Some require a 
line to be added to the AUTOEXEC.BAT to run properly.

  Diamond SpeedStar Plus & 24         VMODE
  Orchid Prodesigner IIs              DYNASCAN
  Trident 8900c                       TVGACRTC
  Cirrus Logic                        CLMODE
  STB Powergraph                      SETMODE
  Orchid Fahrenheit 1280              FSCAN
  Diamond Speedstar Pro               PROMODE
  Diamond Speedstar 24x               24XMODE

Questions regarding these utility programs should be addressed to the 
vendor's technical support representative.
