Chapter 3: BIOS Setup Utility

Onboard FDC Controller

This option enables the onboard floppy disk drive controller.

Onboard Serial Port 1

This option is used to assign the I/O address and interrupt request (IRQ) for

onboard serial port 1/2.

UART Mode Select

This field is available if the Onboard Serial Port 2 field is set to any option but

Disabled. . UART Mode Select enables you to select the infrared communication

protocol-IrDA, ASKIR or SCR.

UR2 Duplex Mode

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 can transmit

and send information simultaneously. Half-duplex is the transmission of data in

both directions, but only one direction at a time.

Onboard Parallel Port

This option is used to assign the I/O address and interrupt request (IRQ) for the

onboard parallel port.

Parallel Port Mode

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 (Ex-

tended Capabilities Port) and ECP+EPP.

SPP allows data output only. Extended Capabilities Port (ECP) and Enhanced

Parallel Port (EPP) are bi-directional modes, allowing both data input and output.

ECP and EPP modes are only supported with EPP- and ECP-aware peripherals.

ECP Mode Use DMA

When the onboard parallel port is set to ECP mode, the parallel port can use DMA

3 or DMA 1.
