Clear CMOS (J9C1-A, Pins 4,5,6)

Allows CMOS settings to be reset to default values by moving the jumper from pins 4-5 to pins
5-6 and turning the system on. When the system reports that "NVRAM cleared by jumper", the
system can be turned off, and the jumper should be returned to the 4-5 position to restore normal
operation. This procedure should be done whenever the system BIOS is updated. Default is for
this jumper to be on pins 4-5.
1.11.3

Password clear (J9C1-A, Pins 1,2,3)

Allows system password to be cleared by moving the jumper from pins 1-2 to pins 2-3 and turning
the system on. The system should then be turned off and the jumper should be returned to the 3-5
position to restore normal operation. This procedure should only be done if the user password has
been forgotten. The password function is effectively disabled if this jumper is in the 1-3 position.
Default is for the password to be enabled (3-5 position).
1.11.4

CMOS Setup Access (J9C1-B, Pins 1,2,3)

Allows access to CMOS Setup utility to be disabled by moving this jumper from the 1-2 position
to the 2-3 position. Default is for access to setup to be enabled (1-2 position).
