The other information that's useful to have (which I unfortunately
don't have a reference for at the moment) is what devices use what
interrupts.  That way you don't change your hard disk or keyboard
interrupt accidentally.  I never found enough information on this in
the various PC hardware books I checked.  Unfortunately, the only
really good reference I ever found on the subject was the manual for
the AMX-86 real-time operating system.  They had to muck with a lot of
the hardware to make the system work well, and they told you in the
manual how they did it all, with source code.
