OnBoard Parallel Port:
This option specifies the base I/O port address of parallel port on
the system board. The available settings are Disabled, 378h,
278h, and 3BCh.
Parallel Port Mode:
This option specifies the parallel port mode. The available
settings are Normal, Bi-Dir, EPP, and ECP.
Normal: The normal parallel port mode is used.
Bi-Dir: Use this setting to support bi-directional transfers on
the parallel port.
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.
