Subject:	int86

Could some kind soul put me out of my int86 misery by either pointing
me at instructions for or examples of the use of int86 or telling me
what I'm doing wrong?  When I invoke int86, everything goes smoothly
up to where the int 0x?? (0x13, disk I/O) is executed.  Instead of
diving into the BIOS' disk routines, an exception 19 (i.e. 0x13) is
taken, stopping my program at that point.  This happens under all of
go32, debug32, and aout2exe.  Someone (crt0?) is intercepting the
interrupt before the BIOS can handle it.  Since int86 is in djgpp's
library I took it that this means one can do BIOS calls under djgpp,
or does that not follow?
