    timer 0 controls the system date/time.

    timer 1 controls dram refresh. You USED to be able to gain slight performance increases back in the 80286 days by decreasing this timer so that it didn't refresh every 15us. Dram in all modern systems is self refreshing and doesn't use any CPU overhead to do so, so this timer is pretty much unused.

    timer 2 is for generating tones to the speaker.
