Parallel Port Mode [Normal]
Use the Parallel Port Mode option to select the mode the parallel port operates in.
Normal D
EFAULT
The normal parallel port mode is the standard mode
for parallel port operation.
Bi-directional
Parallel port outputs are 8-bits long. Inputs are
accomplished by reading 4 of the 8 bits on the
status register.
EPP
The parallel port operates in the enhanced parallel
port mode (EPP). The EPP mode supports
bi-directional communication between the system
and the parallel port device and the transmission
rates between the two are much faster than the
Normal mode.
ECP+EPP
The parallel port operates in the extended
capabilities port (ECP) mode. The ECP mode
supports bi-directional communication between the
system and the parallel port device and the
transmission rates between the two are much faster
than the Normal mode
The parallel port is also be compatible with EPP
devices described above
Parallel Port IRQ [IRQ7]
Use the Parallel Port IRQ selection to set the parallel port interrupt address.
IRQ5 IRQ5 is assigned as the parallel port interrupt address
IRQ7 D
EFAULT
IRQ7 is assigned as the parallel port interrupt address
Serial Port1 Address [3F8/IRQ4]
Use the Serial Port1 Address option to select the Serial Port 1 base address.
