Hi;

I am trying to use a BIOS routine INT 15 function 83 : Set event wait
interval from djgpp. How do I fool the bios routine to use my pointer
correctly (ES:BX is supposed to point to a byte )? Following the code in
gcrt0.s and dosmem.s, I end up with segmentation violation/pagefault.
I am using DJGPP 1.10 (gcc/g++/goc 2.4.1).

Thanks a lot for your help.
