Setting Jumper Switches
Jumpers are sets of pins which can be connected together with jumper caps. The jumper caps change the way the mainboard operates by changing the electronic circuits on the mainboard. If a jumper cap connects two pins, we say the pins are SHORT. If a jumper cap is removed from two pins, the pins are OPEN.
Jumper JP1: Enable/Disable Fax/Modem
Use this 2-pin jumper to enable or disable the onboard Fax/Modem connector. If the audio jumper JP2 is disabled, the Fax/Modem is also disabled, no matter what JP1 is set to.

Jumper JP2: Enable/Disable Onboard Audio
Use this 2-pin jumper to enable or disable the onboard audio system. If you install another sound card, you must disable the onboard audio subsystem. If you use this jumper to disable the audio subsystem, it automatically disables the onboard Fax/Modem, even if Fax/Modem jumper JP1 is enabled.

Jumper JP7: Clear CMOS Memory
Use this jumper to clear the contents of the CMOS memory. You may need to clear the CMOS memory if the settings in the Setup Utility are incorrect and prevent your mainboard from operating. To clear the CMOS memory, disconnect all the power cables from the mainboard and then move the jumper cap into the CLEAR setting for a few seconds.
