To program a oneshot you need a time base to decide the next time to be
interrupted, that's the TSC, and a device to interrupt after the next
shot is expired, under UP that's the 8254.

Since there are not many ways to do such a thing, tell me how you would
program it and I'll place TSC and 8254 in due places, for you. Maybe in
that way you'll understand.

Ciao, Paolo.
