- Are you trying to run in SVGA mode (i.e., something above standard VGA)?
- I had the same problem for awhile (navigating the WPS with out-of-sync
- video is fun!). I was running in 1024x768x256 (or trying to) on an
- ET4000 card. I had to boot native DOS (reset switch), set my video modes
- from there, and create a new SVGADATA.PMI file using 'SVGA ON.' Replacing
- this file over the old one in \OS2 did the trick.
-
- It seems that VMODE under OS/2 does not run the same as under native DOS.
- (Possibly due to the way OS/2 handles the video.) Trying to set a custom
- monitor under OS/2 didn't work for me; the same settings came in clearly
- under DOS.
