I liked Morten Welinde's suggestion since setver has caused me
some problems in the past. I found the string "MSDOS Version 5.00"
in EXE2BIN.EXE and changed it to "MSDOS Version 6.00", but this had
no effect (still got "Incorrect version" message). Can anyone tell
me what the version checking code looks like?

If the answer is RTFM I'd welcome any references - I know that I
have just enough knowledge to be dangerous and I'd like to gain
enough to be effective.
