System jumpers

The jumpers allow you to set certain characteristics of the system. Some jumpers are reserved and are not described in this section. Do not change any jumper unless it is necessary to configure the system. In some cases, changing the settings of reserved jumpers can cause damage to the system board.

Clear CMOS jumper

This jumper allows you to clear the CMOS memory. You should only do this if you cannot access the normal methods of modifying the CMOS and modifications to the CMOS are necessary. Clearing CMOS memory returns all BIOS Setup settings to the default values.

CPU speed setting jumper

This jumper allows you to set the speed of the processor. Both processors, in dual processor configurations, must have the same speed rating. If processors of different speeds are used in the same system, the processors must run at the speed of the slower processor.

I2O feature connector

This connector is designed to accommodate an intelligent input/output

(I2O) compatible expansion card. At the time this manual was published, no fully I2O compatible board was available for testing.

Battery

Provides the power to maintain the CMOS memory when the system is turned off or unplugged.
