3.6.18 Onboard Parallel Port
This field sets the address of the on-board parallel port connector. You can select
either "378/IRQ7", "278/IRQ5", "3BC/IRQ7", or "Disabled". If you install an I/O card
with a parallel port, make sure there is no conflict in the address assignments. The
single board computer can support up to three parallel ports, as long as there are no
conflicts for each port.
3.6.19 Parallel Port Mode
This field allows you to set the operation mode of the parallel port. The setting “Nor-
mal” allows normal speed operation, but in one direction only. “EPP” allows bidirec-
tional 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.
3.6.20 EPP Mode Select
This field allows you to select EPP port type 1.7 or 1.9. The choices: "EPP1.9",
"EPP1.7".
3.6.21 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, you can select DMA channel 1 or DMA channel 3. Leave
this field on the default setting.
