Wait man...
What do you understand when someone says "Open the program in a MS-DOS shell"???
You must
1) open the MS-DOS shell (START -> programs-> MS-DOS shell or so)
2) To simplify the question, copy the interested files in c:\ before doing in step 1)
3) Type "cd\" to go to C:\ root (you might start in c:\windows: if wrong, go manually to c:\ typing "cd c:\")
4) THEN type what the moderator just suggested you:
command patch.xxx file.bin
5) Complete!
Obtaining your previous results, you maybe double-clicked the .exe file in Windows... God, the Windows generation...
Note: if what I wrote is a river of shit, just excuse me!
