Well, you can disable the patch, it was a good way to do a short dos version test to see if TTD Dos actually run (not really helpful on 64bit OS anyway)
I personally for the challenge while I am learning x86 ASM would like to work out a good way of auto disabling the patch under DOS or a DOS based Windows Version.
NTVDM emulates DOS version 5, I thought. 95 is 7.0, 98 is 7.1, Me is 8.0, from memory.
I will have to check that for XP as NT 3.1 to 2000 I have read definitely report/emulate version 5. The DOS boot files that XP puts on a bootable floppy however are version 8. I know there are two interrupts for detecting if Windows is running from DOS, one for 3.x and earlier and one for 95 (to presumably ME) I plan to combine that check with the DOS version check.
