Onboard Serial Port 1/2 (3F8/IRQ4)(2F8/IRQ3)
This option is used to assign the I/O address and interrupt request (IRQ) for onboard serial
port 1/2 (COM1/2).

• UR2 Duplex Mode (Half):This field is available when UART Mode is set to
either ASKIR or IrDA. This item enables you to determine the infrared function
of the onboard infrared chip. The options are Full and Half (default). Full-
duplex means that you transmit and send information simultaneously. Half-
duplex is the tranmission of data in both directions, but only one direction at a
time.

Enables you to set the data transfer protocol for your parallel port. There are four options:
SPP (Standard Parallel Port), EPP (Enhanced Parallel Port), ECP (Extended Capabilities
Port) and ECP+EPP.
