Enabling the Timers

The BIOS or operating system PnP code should route the interrupts. This includes the Legacy Rout bit, Interrupt Rout bit (for each timer), and interrupt type (to select the edge or level type for each timer).

The Device Driver code should do the following for an available timer:

  1. Set the Overall Enable bit (Offset 10h, bit 0).
  2. Set the timer type field (selects one-shot or periodic).
  3. Set the interrupt enable.
  4. Set the comparator value.
