Onboard Parallel Port
This option enables the parallel port on the motherboard and
specifies the parallel port base I/O port address. The settings are
Auto, Disabled, 378, 278, or 3BC.
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
Description
Normal
The normal 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 transfer rates of
ap
approximately 2.5 Mbs. ECP provides sym-
metric bidirectional communications.
Parallel Port DMA Channel
This option is only available if the setting for the Parallel Port
Mode option is ECP. The settings are 0, 1, or 3.
Parallel Port IRQ
IRQ7 is used for the parallel port (LPT1). The IRQ can be changed
to IRQ5.
