Chapter 2: Installation

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads to prevent the accidental clearing of CMOS. To clear CMOS, use a metal object such as a small screwdriver to touch both pads at the same time to short the con- nection. Always remove the AC power cord from the system before clearing CMOS. Note: For an ATX power supply, you must completely shut down the system, remove the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog is a system monitor that can reboot the system when a software application hangs Close Pins 1-2 to reset the system if an applica- tion hangs. Close Pins 2-3 to generate a non- maskable interrupt signal for the application that is hung up. See the table on the right for jumper settings. Watch Dog must also be enabled in the BIOS.
