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 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

ECP+EPP

The parallel port is compatible with ECP and 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.

Disabled

No base address is assigned to Serial Port 1

3F8/IRQ4 D

EFAULT

Serial Port 1 I/O port address is 3F8 and the interrupt

address is IRQ4

3E8/IRQ4

Serial Port 1 I/O port address is 3E8 and the interrupt

address is IRQ4
