XP and DOS.WIN 9x do and will function differently for Vesa calls. I
have found that Vesa under 2000/XP do not support the tripple buffer
modes and a few or the higher resolutions. This in on the sam PC
booting XP and then DOS 6.22 for a comparision.

I have no idea why or what causes the differences.

I would advise that you save some time and look at Allegro for the
graphics routines. See the Allrgeo librayry at
http://alleg.sourceforge.net/
