3.10.7 Onboard Serial Port 2 (2F8H/IRQ3)
The settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10,
and Disabled for the on-board serial connector.
3.10.8 Onboard Parallel Port (378H/IRQ7)
This field sets the address of the on-board parallel port connector.
You can select either 3BCH/IRQ7, 378H/IRQ7, 278H/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 PCA-6166 can
support up to three parallel ports, as long as there are no conflicts for
each port.
3.10.9 Parallel Port Mode (ECP + EPP)
This field allows you to set the operation mode of the parallel port.
The setting “Normal” 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 bidirec-
tional mode and at a speed faster than the maximum data transfer rate.
“ECP + EPP” allows normal speed operation in a two-way mode.
3.10.10 ECP Mode Use DMA
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 channel 3, or Disable. Leave this field
on the default setting.
