278h Æ assign this I/O address to LPT1
3BCh Æ assign this I/O address to LPT1

Parallel Port Mode:
This option specifies the parallel port mode. ECP and EPP are
both bi-directional data transfer schemes that adhere to the
IEEE P1284 specifications. This Parallel Port Mode includes
four options “Normal”, “Bi-Dir”, “EPP”, and “ECP”.

Setting

Description

Normal Uni-direction operation at normal speed

Bi-Dir Bi-direction operation at normal speed

EPP

The parallel port can be used with devices that adhere to
the Enhanced Parallel Port (EPP) specification. EPP uses

the existing parallel port signals to provide asymmetric
bi-directional data transfer driven by the host device.

ECP

The parallel port can be used with devices that adhere to
the Extended Capabilities Port (ECP) specification. ECP

uses the DMA protocol to achieve data transfer rates up to
2.5 Megabits per second. ECP provides symmetric

bi-directional communication.

EPP Version :

This option is only valid if the Parallel Port Mode option is set
to EPP. This option specifies the version of the Enhanced
Parallel Port specification that will be used by AMIBIOS.

Parallel Port DMA Channel :

This option is only available if On Board Parallel Port is
set to fixed I/O address and the setting of Parallel Port
Mode
is ECP. This option sets the DMA channel used by
ECP-capable parallel port.
