3.6.9 Onboard Parallel Port (378H/IRQ7)
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.
3.6.10 Onboard 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.
3.6.11 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.
3.6.12 Parallel Port EPP Type
This field allows you to select EPP port type 1.7 or 1.9. The choices:
EPP1.7, 1.9.
