Clear CMOS Data Jumper
The CMOS jumper JP10 is used to clear the system configuration data
currently stored in the CMOS RAM. All system setup information (hard
disk type, date/time, etc...), stored in the CMOS, will be destroyed. This
function would be useful if you were to forget the user password for the
system.
