Parallel Port Mode
Sets the operation mode for the parallel port.
When set to Normal mode, allows normal
speed one-way operation. When Bi-Direc-
tional, allows normal speed operation in a
two way mode.
EPP (Enhanced Parallel Port) allows bi-
directional parallel port operation at maxi-
mum speed.
ECP (Extended Capabilities Port) allows
parallel port to operate in bi-directional
mode and at a speed higher than the maxi-
mum data transfer rate.

Assigns an IRQ for the parallel port. If
you install an add-on card that has a
parallel port whose address conflicts
with the onboard parallel port, a with the
onboard parallel port, a warning appears on

to one that does not conflict.
