3.6.10 Onboard Parallel Port (378/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.
3.6.11 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 bidirectional mode and at a
speed faster than the maximum data transfer rate. “ECP + EPP” allows
normal speed operation in a two-way mode.
3.6.12 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 or DMA channel 3. Leave this field on the default set-
ting.
3.7 Power Management Setup
The power management setup controls the CPU card’s “green” features to
save power. The following screen shows the manufacturer’s defaults:
