The CPU card can support up to three parallel ports, as long as there are no conflicts
for each port.

Parallel Port Mode
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
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

EPP Mode Select
This field allows you to select EPP port type 1.7 or 1.9.

ECP Mode Use DMA
This selection is available only if you select "ECP" or "ECP + EPP" in the Parallel Port
