Write your reply.

assistant: That isn't a mode-change!  That is function 03h, which is Get Cursor Position
and Size.  According to my reference (_PC_Interrupts_ by Ralf Brown & Jim
Kyle), setting the high bit of AL will suppress the initial screen clearing,
so try this:
        mov     ax, 00083h
        int     10h
However, be careful about using this with an AT&T VDC... it means something
different for that adapter.
I'm not sure why it would do that
What you could do is reserve an area for storing & recalling the information
stored onscreen:
********
        push    ds
        mov     ax, 0B800h
        mov     ds, ax
        mov     ax, 08800h      ; this may not be the best memory to use, but
                                ; it's easier for the example.
        mov     es, ax
        xor     si, si
        mov     di, si
        mov     cx, 04000h      ; make sure to get whatever size buffer, even
                                ; if it's more than 80x25.
        rep     movsw           ; save entire screen
        mov     ax, 00003h
        int     10h             ; change the mode, clearing the screen
        push    es
        push    ds
        pop     es
        pop     ds
        mov     cx, 04000h
        rep     movsw           ; restore saved screen

I don't want to do a cracking lesson, i can tell you the theory in

- find the code where the check is

One good method hard to crack that comes into my mind, is to copy on

could be the skeme of the first level) and read it with some
nonstandard port use.

I've discovered yesterday that the bug of bugged Pentiums genertes
a little bad approximation only on floating-point divisions!
It means that:
- only software which uses the special fpu of the p5 will run incorrectly
  on very few times
- software that works on 486 do not make te p5 bug to appear
- the error is on an approximation i.e. if i am playing a game like
  quake (i dont know if this game uses p5 fpu but others perhaps)
  1 time every 3 hours in the worst case, the bug would color the
  12363th pixel in white for a single frame
I am sorry i am a little simple-minded but i'd like to buy some bugged
p5 (let's have 4/5 pentiums at 300$) and play deathmach till starving!!
=)
Simply joking: i'd like to know what's the problem if i have a bugged p5
and i know i'll not run some sort of mathematical software or i'll not
use it ti control my private collection of nuclear missles!! =)

All interrupts _are_ disabled by cli. This, however, is interpreted in the
strict original sense of _hardware_ interrupts. The int 010 you do is a call
to the interrupt handler at position 010 in the list of interrupts (aka the
interrupt vector).

CLI disables only hardware interrupts asserted on the INT pin of the
processors. Software int instruction and NMI generated interrupts do not look
at DI bit.
Using that CLI in the above structure is questionable as the int instruction
by itself disables the interrupts. So the only point of it is when you want
to protect a  complete block of operations. (Well, and you must hope the
interrupt handler do not use STI anywhere. :)

While you're in gdb you should ( assuming things are working correctly)
be able to do most debugging type things other than actually running the
program.  E.g. looking at the values of variables and such.
The video you use shouldn't really make much difference - gdb is
strictly text mode in any case.  Since you're working with a core dump
instead of a progra, they don't even have to play tricks to keep the
output from the debugger separate from the output from the program.
