It seems to be wrong. My program with these lines reports "Invalid graphics
mode". Maybe this is the problem of my video card? It is Matrox Millenium
G400.

Well, there can be a kind of misunderstanding --- GraphDriver=10 helps
ising vesa modes with go32v2 version, not win32. The nonsence is that no
other value of GraphDriver helps!!!

Hope I didn't disturb you too much with my (probably stupid) questions,
