CMOS Clear
Refer to Table 2-25 for instructions
on how to clear CMOS. Always re-
move 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 use JBT1 to clear
CMOS. Replace JBT1 back to the
pin 1-2 position before powering
up the system again. Do not use
the PW_ON connector to clear
CMOS.

Jumper JPA3 allows you to change
the speed of the 64-bit PCI slot.
The default setting is 66 MHz.
Note: If you have installed a RAID
card into the RAID adapter port and
a PCI slot into the 64-bit 66 MHz
PCI slot, you must set this jumper
to 33 MHz. Refer to Table 2-26 for
jumper settings.
