2.7 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". Jumper FSB_SEL0 (see p.7 item 25) FSB_SEL1 (see p.7 item 26) Setting 2_3 FSB_SEL0 1_2 FSB_SEL1 FSB 100MHz 1_2 FSB_SEL0 1_2 FSB_SEL1 FSB 166MHz 2_3 FSB_SEL0 2_3 FSB_SEL1 FSB 133MHz 1_2 FSB_SEL0 2_3 FSB_SEL1 FSB 200MHz Note:The setting of the CPU front side bus frequency of this motherboard is by means of the adjustment of jumper-setting. Please follow the figures above to set the CPU front side bus frequency. Please note that the setting of FSB 200MHz will function only when the installed CPU supports FSB 200MHz. PS2_USB_PWR1 1_2 2_3 Short pin2, pin3 to enable (see p.7 item 22) +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. CLRCMOS1 Clear CMOS CLRCMOS2 (see p.7 item 17) solder points (see p.7 item 27) 2-pin jumper Note: CLRCMOS1 and CLRCMOS2 allow 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. There are 2 ways for you to clear and reset the system parameters to the default setup. Please turn off the computer and unplug the power cord, then you may either short the solder points on CLRCMOS1 by using metal material, e.g., a paper clip for 3 seconds; or you may use a jumper cap to short the pin on CLRCMOS2 for 3 seconds. Please remember to remove the paper clip or the jumper cap after clearing the CMOS. 12
