BIOS Default (that is, CMOS Clear) and Password Reset Usage Procedure
The BIOS Default (that is, CMOS Clear) and Password Reset recovery features are designed
such that the desired operation can be achieved with minimal system downtime. The usage
procedure for these two features has changed from previous generation Intel
The following procedure outlines the new usage model.
9.1.1
Set BIOS to default (that is, Clearing the CMOS)
To clear the CMOS, perform the following steps:
1. Power down the server. Do not unplug the power cord.
2. Open the server chassis. For instructions, see your server chassis documentation.
3. Move jumper from the default operating position (covering pins 1 and 2) to the
reset/clear position (covering pins 2 and 3).
4. Wait five seconds.
5. Remove AC power.
6. Move the jumper back to the default position (covering pins 1 and 2).
7. Close the server chassis.
8. Power up the server.
The CMOS is now cleared and can be reset by going into the BIOS setup.
Note: Removing AC power before performing the CMOS clear operation causes the system to
automatically power up and immediately power down, after the procedure is followed and AC
power is re-applied. If this happens, remove the AC power cord again, wait 30 seconds, and re-
install the AC power cord. Power up the system and proceed to the <F2> BIOS Setup utility to
reset the preferred settings.
9.1.2
Clearing the Password
To clear the password, perform the following steps:
1. Power down the server. Do not unplug the power cord.
2. Open the chassis. For instructions, see your server chassis documentation.
3. Move jumper from the default operating position (covering pins 1 and 2) to the password
clear position (covering pins 2 and 3).
4. Close the server chassis.

If pins 2-3 are connected when AC power unplugged, the CMOS settings clear in 5
seconds. Pins 2-3 should not be connected for normal system operation.
ME Firmware Force Update Mode – Disabled (Default)
ME Firmware Force Update Mode – Enabled
BMC Firmware Force Update Mode – Disabled (Default)
BMC Firmware Force Update Mode – Enabled
These pins should have a jumper in place for normal system operation. (Default)
To clear administrator and user passwords, power on the system with pins 2-3 connected.
The administrator and user passwords clear in 5-10 seconds after power on. Pins 2-3
should not be connected for normal system operation.
