Clear CMOS & JBT1
Clear CMOS and JBT1 are used to clear the saved system setup con-
figuration stored in the CMOS chip. To clear the contents of the CMOS
usng JBT1, short the two pads of JBT1 with metallic conductor such as
a flathead screwdriver. Clear CMOS works the same way but is a push
button switch. This will erase all user settings and revert everything to
their factory-set defaults.
