Mainboard Jumpers Described
Jumpers are small groups of pins that can be connected or disconnected
with jumper caps. To connect a jumper, carefully place the jumper cap
over the pins you wish to connect, then gently press down.
The mainboard uses six jumpers, allowing great system flexibility.
However, most system settings are stored in battery-backed CMOS
(Complimentary Metal-Oxide Semiconductor) memory. You can use the
BIOS SETUP program to change settings stored in the CMOS.
Other mainboards use jumpers to configure upgrade options and
parameters on the mainboard. Pantera mainboards use the SETUP
program and the FLASH programming utility instead, making BIOS
changes and upgrades without removing the BIOS chip.
FLASH1
The FLASH1 jumper allows or disallows reprogramming of the FLASH
BIOS with the FLASH utility program. The factory default (NORMAL)
setting allows you to reprogram the BIOS with the FLASH utility.
CLR1
The CLR1 jumper holds or resets the factory default BIOS settings stored
in the CMOS (Complimentary Metal-Oxide Semiconductor) BIOS chip.
You should not clear the CMOS memory unless it becomes corrupted and
cannot be reprogrammed with the SETUP program, which also can reset
the factory default BIOS settings. To clear the CMOS memory, turn off
system power, then momentarily place the jumper in the CLEAR
position, then return the jumper to the NORMAL position. Your system
will not operate with the jumper in the CLEAR position, so be sure to
return the CLR1 jumper to the NORMAL position.
