Hey, gimme a break. It worked on all the systems I have available to me.
Plus, I've attempted to improve it, mostly in error-catching + so on,
so get 1.1. If it still doesn't work, uh, carry on with the beatings.

Actually, if it doesn't work still, please try running Quake to see if
it can play your CD-ROM. If it can, it must not be a DJGPP-specific thing.
Otherwise, my spec must be wrong. It's a Microsoft spec, so how could that
be?
