UART Mode Select [Normal/IrDA/ASKIR/SCR]

UR2 Duplex Mode [Half/ Full]

Onboard Parallel Port: This field sets the address of the

on-board parallel port connector. You can select either

3BC/IRQ7, 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 three 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 bi-directional 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.

ECP Mode Use DMA: In ECP Mode Use DMA, you can

select DMA channel 1 or DMA channel 3. Leave this field

based on the default setting.
