OnBoard Parallel Port
This option enables the parallel port on the CPU board and
specifies the parallel port base I/O port address. The settings are
Auto, Disabled, 378h, 278h, 3BCh.
Parallel Port IRQ
IRQ7 is used for the Parallel Port(LPT 1). The IRQ can be
changed to IRQ5, or auto-selected(Auto) .
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 communla-
tions.
Parallel Port DMA Channel
This option is only available if the setting for the Parallel Port
Mode option is ECP.
The settings are Auto, None, 0, 1, 2, 3.
Onboard IDE
This option specifies the onboard IDE controller channels that will
be used. The settings are Primary, Secondary, Both, or Disabled.
