While it might be possible to pull off a gross hack like this under Windows 95/98/ME, it most certainly isn't possible on NT, 2000 or XP. Any attempt to call the old DOS BIOS interrupts will cause your program to crash with an illegal operation error.
for nt, 2000, xp, you have to write a vxd, using the windows ddk for low level access. and if you are able to get ring 0 access on it, you can configure the tables such that you can use the old bios interrupts
