Don't use `intdosx', use `__dpmi_int' instead.  `intdos' is only good
for a small subset of DOS functions it knows about.

Section 18.1 of the FAQ explicitly tells you NOT to use `int86' and
`intdos' except for functions that it supports, and points to the
place in the library docs which lists the supported functions.  This
seems to be most directly related to your problem.
