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.
