OSVISPD - VIDEO PROBLEMS USING TSENG ET4000 ADAPTERS IN SVGA
11/01/94
================================================================
VIDEO GOES OUT OF SYNC OR A BLURRED STRIP APPEARS ACROSS
THE TOP OF THE DESKTOP USING TSENG ET4000 ADAPTERS IN SVGA.
================================================================
Please Read Entire Document for Full Explanation of Procedures
----------------------------------------------------------------
SYMPTOMS:
The display looses sync or a blurred strip appears across the
desktop. This can happen when you start the stystem or when
switching between full screen sessions.
RESOLUTION:
- Make sure the BIOS is at the latest revision and the batch #
on the chipset is TC6059AF or higher.
- Run the display adapter utility that came with the adapter
card to set the proper refresh rates for your montior.
- Regenerate the SVGADATA.PMI file.
PROCEDURES:
1. Make sure the batch # on the chipset is TC6059AF or higher
and make sure the bios is at the latest revision, for
example, Diamond's should be at least 4.23.
2. Use RSPDSPI to set video mode back to VGA. This step is
necessary if the desktop is not usable. If the desktop can
be used in SVAG, go to step 6.
3. Open a DOS full screen session and run SVAG ON.
4. Exit the DOS full screen.
5. Open an OS/2 full screen session and run DSPINSTL to
install the SVGA drivers.
DO NOT SHUT DOWN WHEN PROMPTED!
Note: For OS/2 for Windows use Selective Install instead of
DSPINSTL.
6. Open a DOS full screen session and run the display adapter
utility that came with the display adapter card. For
example, Diamond's utility is called VMODE. Set the refresh
rates for your monitor. The higher you set the refresh the
better the performance of your monitor, but do not exceed the
limitations of the monitor (See the specifications).
7. Run SVGA ON to regenerate the SVGADATA.PMI file.
8. Exit the DOS fullscreen.
9. Shutdown and restart the system.
