I'm trying to hook a handler into the mouse driver, with int
0x33 and
ax = 0x000c. Well, I need to put an address to a far routine
into
ES:DX, but I'm not quite sure how to do it. I've gotten as
far as
knowing that I need to use
__dpmi_allocate_real_mode_callback()...
but that's as far as I can figure. The documentation on
these functions
seems to be thin at best.
Can someone please assist me in this issue, or at least give
me a
pointer in the right direction (pun intended)?
