Not written in asm - that's its damn problem! :)

Amen! :-)

When (if?) you sort through the replies to your original post, get back
to us with what you're trying to do. Looks like you've got one foot in
dos, and one in 32-bit... won't work unless you "take steps". - dos
extender or switch to pm yourself - and *then* dos interrupts won't work...

I was experimenting to see if I could use DOS interrupts with 32-bit
registers. I know I can do it with 16-bit registers, to some extent.
Most likely because there's some hidden emulation layer that caters to
stupid people who try to write DOS in Windows. ;-) Are interrupts real
interrputs on Windows XP? Or do they end up calling a Win32 function?

To be perfectly honest, I wanted to find a convenient way to do I/O
without resorting to the C library or the evil Win32 API. Interrupts
are simple and relatively easy to use. The C library is very simple and
easy to use, for me, but I can imagine it being somewhat bloated for an
assembly program. I *hate* the Win32 API with a well honed passion,
even for simple things, and I try to avoid it. :-)
