You do know what an exception is, right? In other
words, a hardware interrupt?

So, what you want to do, is define ISR (interrupt
service routines) for each of those vectors... or
at least each of those vectors that haven't been
masked off (check out documents on the PIC if
this seems foreign).

If you don't, whenever you have an exception, your
operating system will triple-fault, and you're
outta luck. At the very least, I'd define one
for the timer, the keyboard, and some of the more
"famous" faults (GPF, double fault, etc).
