card. If you want to use a different controller card to connect the floppy
disk drives, set this field to Disabled.
3.6.13 Onboard Serial Port 1
The settings are "3F8/IRQ4", "2F8/IRQ3", "3E8/IRQ4", "2E8/ IRQ3"
and "Disabled" for the on-board serial connector.
3.6.14 Onboard Serial Port 2
The settings are "3F8/IRQ4", "2F8/IRQ3", "3E8/IRQ4", "2E8/ IRQ3"
and "Disabled" for the on-board serial connector.
3.6.15 Onboard Serial Port 3
The setting are "(3F8, 2F8, 3E8, 2E8, Disable)/(IRQ10, IRQ11, IRQ3,
IRQ4, IRQ5, IRQ7)" for the onboard serial connecto.
3.6.16 Onboard Serial Port 4
The setting are "(3F8, 2F8, 3E8, 2E8, Disable)/(IRQ10, IRQ11, IRQ3,

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.
3.6.20 Parallel Port Mode
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 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.
