A jumper is a set of two, three or more jumper pins which allow users to make different

system configuration by putting the plastic connector plug (mini-jumper) on it. The

jumper setting is necessary when installing different components onto the mainboard.

(A) JP9: CMOS DATA CLEAR BUTTON

Basically, the BIOS setup program will have all the setting saved in the CMOS

memory so that the system BIOS will know how to initialize the core logic of the

mainboard. In case that you made some wrong setting in the BIOS setup program

and caused the PC system failed to boot, you can use JP9 to clear all the setting

which is saved in the CMOS memory.

1-2 Short: Normal Setting.

2-3 Short: Clear CMOS.
