Onboard Serial Port2
This option enables serial port 2 on the motherboard and specifies the base I/O port address for
serial port 2.
The settings are 3F8h, 2F8h, 3E8h, 2E8h, Disabled or Auto. The Optimal and Fail-Safe default
settings are Auto.
Serial Port2 Mode
Choose Standard, IrDA and ASK IR for IrDA serial interface.
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 378h, 278h, 3BCh, Disabled or Auto.
The Optimal and Fail-Safe default settings are Auto.
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. 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 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 approximately 2.5 Mbs. ECP provides symmetric
bidirectional communications.

EPP Version
Choose 1.9 or 1.7.
Parallel Port IRQ
This option is only available if the setting for the Onboard Parallel Port option is a 378h, 278h or
3BCh. The settings are 5 or 7.
