Chapter 2: System Features 31
System jumpers
These jumpers allow you to set certain characteristics of the system. Do not
change any jumper unless it is necessary to configure the system.
There may be additional jumpers on the system board. These jumpers are
reserved and should not be changed. 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 complimentary metal-oxide
semiconductor (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. This jumper occupies pins 1-3 of the
connector. See “CMOS Clear jumper” on page 176 for more information
on setting the CMOS clear jumper.
Password clear jumper
Setting this jumper allows you to clear the passwords. The default jumper
position protects the passwords. Use this jumper only if you have forgotten
the passwords and cannot access the system. This jumper occupies pins 5-7
of the connector. See “Password Clear jumper” on page 177 for more
information on using the password clear jumper.
Recovery boot jumper
The recovery boot jumper should be used only in the event of a failed BIOS
update. If you attempt a BIOS update and the update fails, set this jumper
and reboot the system. The system attempts to recover the previous version
of the BIOS as it boots up. This jumper occupies pins 9-11 of the connector.
See “Recovery Boot jumper” on page 178 for more information on setting
the recovery boot jumper.
