Parallel Port Mode This option specifies the parallel port mode. ECP and EPP are both bidirectional data transfer schemes that
adhere to the IEEE P1284 specifications. The settings are:
Setting
Normal
Bi-Dir
EPP
ECP
Parallel Port DMA This option is only available if the setting for the Parallel Port Mode option is ECP.
The settings are Disabled, DMA CH (channel) 0, DMA CH 1, or DMA CH 3. The default setting is Disabled.
Onboard Triton IDE This option specifies the onboard IDE controller channels that will be used. The settings are Primary,
Secondary, Both, or Disabled. The Optimal and Fail-Safe default settings are Primary.
Chapter 4 WINBIOS Setup
The normal parallel port mode is used. This is the default setting.
Use this setting to support bidirectional transfers on the parallel port.
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.
The parallel port can be used with devices that adhere to the Extended Capabilities Port
(ECP) specification. ECP uses the DMA protocol to achieve transfer rates of
approximately 2.5 Mbs. ECP provides symmetric bidirectional communications.
