using int 13h to access DOC

Hi guys...

Shoot this down: Since the M-Sys firmware in the DOC simply installs
an int 13h handler, why not use it to access the DOC using "bios"
calls.  I realize that the kernel probably overwrites that handler but
that could be fixed.  I don't know, however, about using a real-mode
interrupt from a device driver.  It seems too simple to work.  What
have I overlooked?
