set, change, and delete the power-on password. A user who types the power-on
password has access to only the limited Setup utility menu; the user can set,
change, and delete the power-on password, if the system administrator has given
the user that authority.
Power-on password: If a power-on password is set, when you turn on the server,
you must type the power-on password to complete the system startup. You can use
any combination of6-20printable ASCII characters for the password.
When a power-on password is set, you can enable the Unattended Start mode, in
which the keyboard and mouse remain locked but the operating system can start.
You can unlock the keyboard and mouse by typing the power-on password.
If you forget the power-on password, you can regain access to the server in any of
the following ways:
v If an administrator password is set, type the administrator password at the
password prompt. Start the Setup utility and reset the power-on password.
v Remove the battery from the server and then reinstall it. See the Problem
Determination and Service Guide on the IBM System x Documentation CD for
instructions for removing the battery.
v Change the position of the power-on password switch (enable switch 4 of the
system board switch block (SW3) to bypass the power-on password check (see
“System-board jumpers” on page 30 for more information).
Attention: Before you change any switch settings or move any jumpers, turn
off the server; then, disconnect all power cords and external cables. See the
safety information that begins on page vii. Do not change settings or move
jumpers on any system-board switch or jumper blocks that are not shown in this
document.
The default for all of the switches on switch block (SW3) is Off.
While the server is turned off, move switch 4 of the switch block (SW3) to the On
position to enable the power-on password override. You can then start the Setup
utility and reset the power-on password. You do not have to return the switch to
the previous position.
The power-on password override switch does not affect the administrator
password.
Administrator password: If an administrator password is set, you must type the
administrator password for access to the full Setup utility menu. You can use any
combination of6-20printable ASCII characters for the password.
Attention: If you set an administrator password and then forget it, there is no way
to change, override, or remove it. You must replace the system board.

you can use to temporarily redefine the first startup device without changing
settings in the Setup utility.
To use the Boot Manager program, complete the following steps:
1. Turn off the server.
