BIOS Setup

To use the IrDA function, follow the steps below.

1. Connect your IrDA cable to connector J3 on the system

board.

2. Set the “UART Mode Select” field to the type of IrDA stand-

ard supported by your IrDA peripheral/device. For better

transmission of data, your IrDA peripheral device must be

within a 30

angle and within a distance of 1 meter.

3. Set the “UR2 Duplex Mode” field appropriately.

UR2 Duplex Mode

Half Data is completely transmitted before receiving data.

Full Transmits and receives data simultaneously.

Onboard Parallel Port

378/IRQ7, 3BC/IRQ7, 278/IRQ5 Selects the I/O address and

IRQ for the onboard parallel port.

Disabled Disables the onboard parallel port.

Parallel Port Mode

The options are SPP, EPP, ECP and ECP+EPP. These apply to a

standard specification and will depend on the type and speed of

your device. Refer to your peripheral’s manual for the best op-

tion.

SPP

Allows normal speed operation but in one direction only.

ECP (Extended Capabilities Port)

Allows parallel port to operate in bidirectional mode and at a

speed faster than the normal mode’s data transfer rate.

EPP (Enhanced Parallel Port)

Allows bidirectional parallel port operation at maximum

speed.
