Passwords
From the Security choice, you can set, change, and delete a supervisor password
and a user password. Depending on how passwords are configured, certain BIOS
configuration utility fields might not be editable by all users, and you might have to
type a password to complete system startup.
Supervisor password
If you set only a supervisor password, you must type the supervisor password to
access all editable fields in the BIOS configuration utility program. You can also
configure the system to require entry of this password to complete the system
startup. If a supervisor password is set, you can also set a user password. You can
use any combination of up to seven characters (A - Z, a - z, and 0 - 9) for the
supervisor password.
If you forget the supervisor password, you can clear CMOS memory to remove the
supervisor password. See “Clearing CMOS memory” on page 47 for instructions.
User password
If you set a supervisor password for a system administrator and a user password
for a user, a system administrator who types the supervisor password has access to
change all editable BIOS configuration utility fields. A user who types the user
password can view all BIOS configuration utility fields but can change values in a
subset of those fields that are editable by the system administrator. If the system is
configured to require entry of a password to complete the system startup, you can
type either password to complete the system startup. You can use any combination
of up to seven characters (A - Z, a - z, and 0 - 9) for the password.
If you forget the user password, you can regain access to the server in any of the
following ways:
v
If a supervisor password is set, type the supervisor password at the password
prompt. Start the BIOS configuration utility program and reset the user password.
v Clear the password by clearing CMOS memory (see “Clearing CMOS memory”
on page 47 for instructions).
IBM Advanced Settings Utility program
Use the Advanced Settings Utility (ASU) program to modify firmware settings from
the command line without the need to restart the system to access the BIOS
configuration utility program. You can also use the ASU program to issue selected
baseboard management controller setup commands. The ASU program supports
scripting environments through a batch-processing mode. For more information and
to download the ASU program, go to http://www.ibm.com/systems/support/.
