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, 378h, 278h, 3BCh.
Parallel Port Mode
This option specifies the parallel port mode. ECP and EPP are
both bidirectional data transfer sechemes that adhere to the IEEE
P1284 specification. The settings are:
Setting
Description
Normal
The normal parallel port mode is used. This is the
default setting.
Bi-Dir
Use this setting 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 exiting 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 approximately 2.5 Mbs. ECP provides symmetric
bidirectional communlations.
Parallel Port IRQ
IRQ7 is used for the Parallel Port(LPT 1). The IRQ can be
changed to IRQ5.
Parallel Port DMA Channel
This option is only available if the setting for the Parallel Port
Mode option is ECP.
The settings are Auto, N/A, 0, 1, 3.
Onboard PCI IDE
This option specifies the onboard IDE controller channels that
will be used. The settings are Primary, Secondary, Both, or
Disabled.
