Green 3VSB LED for SDRAM (LED1)
The green LED turns on if your power cord is still plugged in, which means
3V standby voltage is supplied to mainboard. You can not install or uninstall
memory modules while LED1 is on.
SIR Connector (SIR1)
If you have an Infrared device, this mainboard can implement SIR (Standard
IR) transfer function. To enable the IR transfer function, follow these steps:
Pins Assignment:
1=Not assigned
2=(No Pin)
3=+5V
4=GND
5=IRTX
6=IRRX
Note:
Before connect your IR device, please be sure each IR on board pin
allocation is matchable with the pin of the IR device. Otherwise,
incorrect IR connection may do damage to your IR device.
Step 1.
Attach the 6-pin infrared device cable to SIR1 connector.
(Refer to the above diagram for IR pin assignment.)
Step 2.
Configure the Infrared transfer mode in field "UART Mode Select"
of "Super IO Device" of "Integrated Peripheral" sub-menu in
BIOS setup program. This mainboard supports IrDA, ASKIR,
Normal, or SCR transfer modes.
