3.10.4 Onboard FDC Controller
When enabled, this field allows you to connect your floppy disk
drives to the onboard floppy disk drive connector instead of a
separate controller card. If you want to use a different controller card
to connect the floppy disk drives, set this field to Disabled.
3.10.5 Onboard Serial Port 1 (3F8H/IRQ4)
The settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and
Disabled for the on-board serial connector.
3.10.6 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.
3.10.7 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 CPU card can support up to
three parallel ports, as long as there are no conflicts for each port.
3.10.8 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.
3.10.9 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.
