Bill: There are several old fractint mailing list articles that discuss makefcfg.exe being compiled in such a way that it requires DPMI services, I downloaded csdpmi3b.zip available at http://linux.sarang.net/ftp/mirror/editor/jed/misc/csdpmi/ Download it and and extract it onto a DOS boot floppy Boot your machine with your DOS 6/7 Boot floppy go to the A:\BIN sub-dir Run cwsdpmi.exe -p Then log into to your Fractint sub-directorie Run makefcfg.exe or makefcfg.exe -h Then run "makefcfg.exe true overwrite" If you have any do edit utilities, then... Run edit fractint.cfg You will want to determine your optimal boot video format and remember it's <FKey>. In my case I like to open Fractint up in 1024 x 768 mode, so for me that is F6 Run "makefcfg.exe truecolor F6 overwrite" Run "makefcfg.exe" again just to check everything out If you want to stay in DOS You will have to unload the dpmi tsr, Fractint doesn't seem to run well under it. Run cwsdpmi.exe -u Run fractint.exe fractint should now load with your selected video format as the default startup. If the program loads properly in your dos boot disk configuration it should also load ok in WinXP (Fingers crossed) I still have to go back and edit and tweak my fractint.cfg file to get it all to run just right.....

There's a very interesting setting that I found on my Win95/98 Fractint Dos Box "Properties" window. Right click your Fractint Dos Box, click Properties >Program (tab) >Advanced (radial button). Check out all the different Dos Modes and configurations that you can set your Dos box to. I partuclarily like the "Prevent MS-DOS-based programs from detecting Windows". There are also other specific custom DOS configurations that can also be set. Hmmmm methinks this is the area to really look into...... All the best, Tony Tony, Thanks for the tip. There is no exact equivalent for that selection in XP though. I also found an article in PC Magazine that explains how every application can have its own autoexec and config.sys files. I haven't yet found what to put in them to solve the problem, but I'm still playing. In the meantime, I can continue to boot to DOS. I also want to say that I completely agree with your clear statement of the open-source program issues. I'm one of the folks who'd be willing to pay for Fractint. I fully understand and respect Tim's position on this, though. And, as Tim points out, a 13year life-cycle (and still counting!) is an incredible run in any case. Bill
