◎ 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.
