My demos in Windows XP...

I'm not an expert on it, but as far as I know (and as I said before), you need to have them in %SYSTEMROOT%\System32. Go to a command prompt and type 'echo %SYSTEMROOT%' (without the quotes) (it is almost certainly C:\Windows\ in your case, but it wouldn't hurt to be sure.) The contents of these files is important; if they are corrupted, you probably won't be able to run any DOS programs.

For reference, here are the default contents of these files (Lines starting with REM can be ignored, so I did not include them here):

CONFIG.NT

Code:

dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=40

AUTOEXEC.NT

Code:

@echo off

lh %SystemRoot%\system32\mscdexnt.exe

lh %SystemRoot%\system32\redir

lh %SystemRoot%\system32\dosx

SET BLASTER=A220 I5 D1 P330 T3

If your files look the same as these (plus some lines starting with REM), then this is not the problem.
