Parallel Port Mode
This option specifies the parallel port mode. The settings are Normal,
Bi-Dir, EPP, or 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 DMA
protocol to achieve data transfer rates up to 2.5 Megabits per
second. ECP provides symmetric bi-directional communication.
Parallel Port IRQ
This option specifies the IRQ used by the parallel port. The settings
are Auto, (IRQ) 5, or (IRQ) 7.
Parallel Port DMA Channel
This option is only available when the setting for the Parallel Port
Mode option is ECP. This option sets the DMA channel used by the
parallel port. The settings are DMA Channel 0, 1, or 3.
On-Chip IDE
This option specifies the IDE channel used by the onboard IDE
controller. The settings are Disabled, Primary, or Secondary.
