First I thought DOOM was really tough. When I saw '... professional protection
mode ...' message I thought my time was over. I used to crack games a lot and
I thought I could crack any game, it was just a matter of time. But I don't
know about protected mode much so I assumed that was a beginning of a new age
- the age of games running in protected mode (maybe I'm wrong completely about
DOOM, I must admit I've never tried to find out about protected mode, it's
just beyond me). Last night I had nothing to do and I just decided to run DOOM
under my good old cracking utility I wrote a year ago. Just for fun. The key
point of this program is reprogramming interrupt controller so it still works
even if tricky evil Game took over all interrupts. I expected my computer to
hang first. It didn't. Then I thought DOOM was too smart to let this little
tiny bastard live. That wasn't the case either. I pressed very familiar to me
combination Ctrl-Enter and then Ctrl-Esc to pop-up AFD - I was inside AFD ( I
used to use it 'cause it was small and good enough ), happy and confused. I
tried to resume DOOM and it worked ...
My point, guys, is you just reprogram interrupt controller before running DOOM
to avoid such a confusion. That should be it. I'll never be able to crack your
games then ( my friend will, he knows how to handle reprogrammed interrupt
controllers, he's pretty cool ).

Best wishes to ID, yours sincerely PVP.
