Hi, 

I'm trying to write a TSR, it uses the "Keyboard Busy Loop" interrupt 28h
to pop up. My problem is that I would like to be able to allocate memory
inside my interrupt routine using interrupt 21h subfunction 48h.
I consistantly get the "insufficent memory" error returned to me.

Does any one out there know if I can allocate memory inside an interrupt
routine, and what I have to do to achieve this.

Thank you.
