Jumper Settings

1.UART 2 Selection (JP24 & 25) (SMC37C665IR Only)

If your motherboard is using the SMC37C665IR chipset, besides changing the function of UART2 (serial, parallel, floppy, and infrared) in BIOS setup (see page 38), you must also change the following jumpers. If your motherboard is not using this chipset, UART2 is controlled through BIOS only and these jump- ers will not be available on the motherboard.
