hi there,
i have an important question. i hope that someone out there can help me!!!
i am trying to replace some interrupt vectors in the interrupt table,
using the INT 21H interrupt call. i was trying to use int 21h with
AH=35H and AL=09H (trying to replace the keyboard function/response) and
insert the address of my own routine by using INT 21H with AH=25H and
AL=09H. the problem is that when i run it it pukes and locks up the system,
all interrupts are disabeled. this is not the result that i want!! ;')
i know that it is getting locked up within the interrupt itself and not in
another part of my code.
any suggestion that anyone could offer i would greatly appreciate. please
remember though, i am trying to do this with the INT 21H interrupt call.
thanks in advance,
janet

Perhaps if you posted your message to comp.sys.ibm instead of comp.os.cpm,
you would get a better response. Since Im still using CP/M these days,
I have no contact with the MS-DOS world, and prefer it that way. Maybe
some of the other people who subscribe to this newsgroup feel the same way.
