OnBoard Parallel Port
This setting specifies the base I/O port address of parallel port on the
motherboard. The options are Disabled, 378h, 278h, or 3BCh.
Parallel Port Mode
This setting specifies the parallel port mode. The options are Normal,
Bi-Dir, EPP, ECP.
Normal: The normal parallel port mode is used.
Bi-Dir : To support bidirectional 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
bidirectional data transfer driven by the host device.
ECP:
The parallel port can be used with devices that adhere to the
Entended Capabilities Port(ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5
Megabits persecond. ECP provides symmetric bidirectional
communication.
EPP Version
EPP data or address read cycle 1.9 or 1.7
Parallel Port IRQ
This setting specifies the IRQ used by the parallel port. The options are
Auto , (IRQ)5, (IRQ)7.
