Chapter 2 WINBIOS Setup 61
Peripheral Setup, Continued
Parallel Port Mode This option specifies the parallel port mode. ECP and EPP are both
bidirectional data transfer modes that adhere to the IEEE P1284
specifications. The settings are:
Setting Description
Normal
The standard AT-compatible parallel port mode is used.
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
bidirectional 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 bidirectional
communication.
The Optimal default setting is Normal. The Fail-Safe default setting is not
provided.
EPP Version This option specifies the version of the EPP specification supported by
AMIBIOS. This option can only be selected if the setting of the Parallel Port
Mode option is EPP.
The settings are 1.7 or 1.9. There are no default settings.
Parallel Port DMA Channel This option is only available if the setting for the Parallel Port
Mode option is Extended or ECP. This option sets the DMA channel used by
the parallel port. The settings are DMA CH 0, DMA CH 1, or DMA CH 3.
The Optimal and Fail-Safe default settings are not provided.
