Hello,
I have a problem with reversing an OS-loader / kernel:
It is the evaluation version of the ROM-DOS by Datalight,
which has a small 'bug'. When booting it displays a message
("You are using the eval version blabla..."
und waits for
the user to press ESC. This is what I would like to fix.
But I don't have a clue where to start... The IDA-deadlisting
doesn't give me any hints (too much asm and too little
Interupt-calls ;-) and I don't know how to use a debugger
in this...
So it would be really great if someone could help me with this or
give me a hint on how to proceed with this...
Thanks very much in advance.
