Award BIOS Setup Utility
UART Mode Select
The system board supports IrDA function for wireless connectiv-
ity between your computer and peripheral devices. You may not
use IrDA connector and the COM 2 serial port at the same
time. If you are using the COM 2 serial port, make sure this field
is set to Normal.
To use the IrDA function, follow the steps below.
1.
Connect your IrDA cable to the IrDA connector on the sys-
tem board.
2.
Set the “UART Mode Select” field to the type of IrDA stand-
ard supported by your IrDA peripheral/device (IrDA, ASKIR
or SCR). For better transmission of data, your IrDA periph-
eral device must be within a 30
o
angle and within a distance
of 1 meter.
UR2 Duplex Mode
The options are Half or Full
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
standard specifications 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. If
this mode is selected, the “EPP Mode Select” and “ECP Mode
Use DMA” fields are not configurable.
“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. If this
mode is selected, only the “ECP Mode Use DMA” field is
configurable.
