Hi, all Mariano wrote (June 3):

With WinNT and WinXP DOS programs can not access the video hardware, so only stdvga works. Sorry.

I installed grx2.4.6 on a win2000 machine at work, and couldn't access graphics greater than 480 x 360 x 16. I thought perhaps the problem was specific to that machine, so I copied the whole djgpp directory and brought it home. On a win98 machine ('DOS prompt', not 'command prompt'), the same problem. In demo.pas, I have access to modes 0..15 only. I've run demogrx at high resolutions on both machines in the past. my RHIDE.BAT file says to set grx20drv=stdvga, with various combinations of sizes and resolutions tried with no apparent effect. I'm not sure where to start figuring this out, and would appreciate suggestions. all the best, Toby
