2.5 Jumpers Setup The illustration shows how jumpers are setup. When the jumper cap is placed on pins, the jumper is "Short". If no jumper cap is placed on the pins, the jumper is "Open". The illustration shows a 3-pin jumper whose pin1 and pin2 are "Short" when jumper cap is placed on these 2 pins. Jumper FSB Select Jumpers (FSB_SEL0, FSB_SEL1, FSB_SEL2) (see p.7 item 10) Setting 1_2 FSB_SEL0 OPEN FSB_SEL1 1_2 FSB_SEL2 FSB 200MHz OPEN FSB_SEL0 2_3 FSB_SEL1 1_2 FSB_SEL2 FSB 266MHz 2_3 FSB_SEL0 FSB_SEL1 FSB_SEL2 OPEN 1_2 FSB 333MHz Note: The CPU FSB frequency of this motherboard is determined by jumper-setting. You must adjust "FSB Select Jumpers" according to the FSB of your AMD CPU. Please follow the figures above to set the CPU FSB frequency. PS2_USB_PWR1 1_2 2_3 Short pin2, pin3 to enable (see p.7 item 1) +5V +5VSB +5VSB (standby) for PS/2 or USB wake up events. Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply. JR1 / JL1 Jumpers JR1 (see p.7 item 23) JL1 Note: If JR1 and JL1 Jumpers are short, both the front panel and the rear panel audio connectors can work. Clear CMOS Jumper (CLRCMOS2) (see p.7 item 19) 2-pin jumper Note: CLRCMOS2 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper cap to short the Clear CMOS jumper for 5 seconds. After shorting the Clear CMOS jumper, please remove the jumper cap. However, please do not clear the CMOS right after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action. 13
