Hello All!
I'm having a problem here with a program that works fine on 286 and above, 
but never fails to crash on an XT with a 8088 CPU (it seems to get in some 
sort of infinite loop, and if I try to press ctrl-alt-del it hangs 
completely).
Now I'm sure my program doesn't use any 186+ instructions, so that's not the 
problem. There is also the fact that 8088 divide by zero handler return 
address points at the next instruction instead of the divide instruction, but 
I take that into account also.
Do any of you have some suggestions as to what the cause of this 
incompatability may be ? Most likely it's got something to do with how the 
CPU handles certain instructions and traps, such as int 1 etc.
greetz,
Tom
