While I'm not the person trying to make Fractint work under W2K (works fine under OS/2 for me!), I've tried that trick in the past. The problem I hit then is that Fractint couldn't read or write to those registers, even when it knew about them, because the actual video hardware is not *visible* to apps under W2K. W2K makes visible a "virtual" video card derived from the actual video card hardware as supported by the W2K video driver. (At least, that's my guess.) (FWIW, I've gotten the same results with some video setups under W95.) It might work if the W2K video driver supports it, I had that work with one old video card, but not with newer ones. If I can get them to let me install programs on my WXP system at the office, I'll try Fractint on it there. Unfortunately, can't boot to DOS to check the video registers - system is using NTFS.

This pre-supposes that Fractint is located on a FAT16 or FAT32 partition.
The way I kludged Makefcfg to see the Vesa registers was to boot the PC from a Win95 or a Win98 Boot disk. If you still have one lurking around try booting with a old Plain vanilla Dos 6 or 7 boot disk.
Find your Fractint Drive and Subdirectory.
Run makefcfg.exe. Most of the time makefcfg.exe will find the Vesa registers in High memory somewhere or wherever CMOS has made a hole for your video stuff.
Makefcfg.exe sometimes can't find the vesa registers...I don't know why, but if you run makefcfg 3 or 4 times it will eventually "catch" the Vesa registers at least once.
Hopefully if all went according to Hoyle you will have a fractint.cfg file with all the various video modes pointing to appropriate register addresses for your system.
Remove the boot disk and Reboot your PC inWin2000. Open up your "Dos Box" in Win2000 and run Fractint to see if it all worked out.
Hope this helps.

I had a few thoughts on this topic.
One is, why not boot to DOS to run Fractint? Can Win2000 make a DOS- bootable floppy?
Another DOS alternative is Caldera OpenDOS. See

A down side of this is there would have to be a FAT16 partition for OpenDOS to be able to access the hard drive.
