Thanks for the quick replies. Actually those programs *used* to work for me under XP (albeit with lousy sound and no VESA support) just a few weeks ago. They also work in a pure DOS boot. However, recently I noticed programs crashing when they should not, *even* with VDMS they seem to crash. I wonder what it could be?
