JP1, JP2 are used to set the sys-
tem (front side) bus speed for the
processors. It is best to keep this
jumper set to Auto. This jumper is
used together with the CPU Clock
setting in BIOS. See the table on
the right for jumper settings.

Watch Dog Enable/Disable
JP8 enables the control of the
Watch Dog function. Watch Dog
is a system monitor that can
reboot the system when a soft-
ware application is "hung up".
Pins 1-2 will cause WD to reset
the system if an applicantion is
"hung up". Pins 2-3 will generate
a non-maskable interrupt for the
application that is "hung up". See
the table on the right for jumper
settings. Watch Dog can also be
enabled via BIOS. (*Note, when
enabled, the user needs to write
his own application software in
order to disable the Watch Dog
Timer.)
