How have I to setup the APIC Timer, that it fires every 10ms?

My Problem is that don?t understand how I control the timer by setting values to the "divide configuration register" and to the "initial count register"!

For a large resolution like this, it's easier to use the normal PIT. It's accurate enough for 10ms, it's available on all PCs, and its rate can be programmed independently of the bus speed.

Nevertheless, have a look at the "Find the FSB speed" thread in alt.os.development.
