
Onboard Serial Port 2 [02F8h]
Serial Port 2 IRQ [IRQ3]
This item allows user to change COM 2 address and IRQ.

Onboard Serial Port 3 [03E8 / IRQ10]
This item allows user to change COM 3 address and IRQ.

Onboard Serial Port 4 [02E8 / IRQ5]
This item allows user to change COM 4 address and IRQ.

UART Mode select [Normal]

Onboard Parallel Port [378 / IRQ7]
This field sets the address of the on-board parallel port connector. You can
select either [378/IRQ7], [278/IRQ5] or Disabled. If you install an I/O card with a
parallel port, make sure there is no conflict in the address assignments. The
CPU card can support up to two parallel ports, as long as there are no conflicts
for each port.

Parallel Port Mode [ECP+EPP]
This field allows you to set the operation mode of the parallel port. The setting
"SPP" allows normal speed operation, but in one direction only. "EPP" allows
bidirectional parallel port operation at maximum speed. "ECP" allows the parallel
port to operate in bi-directional mode and at a speed faster than the maximum
data transfer rate. "ECP + EPP" allows normal speed operation in a two-way
mode

EPP Mode Select [EPP1.7]
This field allows you to select EPP port type 1.7 or 1.9.

ECP Mode Use DMA [3]
This selection is available only if you select "ECP" or "ECP + EPP" in the Parallel
Port Mode field. In ECP Mode Use DMA, you can select DMA channel 1, DMA
