Hi, I'm a bit of a newcomer to djgpp.. maybe you can help me.

I'm creating a program which uses VESA 1 to go to higer resolutions, and
I've had no trouble getting information about the modes available and
whatnot.  What I can't get to work at all is the setmode function (02h),
which is constantly returning 02h in register AH.  This happens despite the
mode I try to switch to.  I have tried the same modes using the Allegro
library and these have worked.  I have downloaded Dark Angel's VESA tutorial
and the examples there do not work (same problem I am having).  I am sure
this problem is to do with a lack of initialization or something.. my
computer is using VESA 1.2

I'd really appreciate any ideas you have.  Thanks.
Xander.
