IBM F50 RS/6000 7025 - Manual (Page 100)

Set Power On Password: Setting a power-on password helps protect information
stored in your computer. You can use any combination of up to eight characters
(A–Z, a–z, and 0–9) for your password. The password you type is not displayed on
the screen. Press Enter when you are finished; you are required to type the
password again for verification.
If you previously had set a power-on password and wanted to remove it, select
Remove Power-On Password.
Note: If you forget your password, you have to shut down the computer and
remove the battery for at least 30 seconds to disable the password. See
Appendix B, “Replacing the Battery” on page B-1 for details.
A password can be set only after the system is turned off and on again.
