Chapter 5: Advanced Serverboard Setup

CMOS Clear

JBT1 is used to clear CMOS (which will also clear any passwords). Instead of pins,

this jumper consists of contact pads to prevent accidentally clearing the contents

of CMOS.

To clear CMOS,

1. First power down the system and unplug the power cord(s).

2. With the power disconnected, short the CMOS pads with a metal object such

as a small screwdriver.

3. Remove the screwdriver (or shorting device).

4. Reconnect the power cord(s) and power on the system.

Note: Do not use the PW_ON connector to clear CMOS.

VGA Enable/Disable

JPG1 allows you to enable or disable

the VGA port. The default position is on

pins 1 and 2 to enable VGA. See the

table on the right for jumper settings.

Watch Dog Enable/Disable

Jumper JWD controls the Watch Dog

function. Watch Dog is a system moni-

tor that can reboot the system when a

software application hangs. Jumping

pins 1-2 will cause WD to reset the sys-

tem if an application hangs. Jumping

pins 2-3 will generate a non-maskable

interrupt signal for the application that

hangs. See the table on the right for

jumper settings. Watch Dog must also

be enabled in BIOS.
