Appendix H Additional Password Security
and Resetting CMOS
This appendix discusses additional password security and CMOS (complementary metal oxide
semiconductor)-related issues for the HP Workstation xw4200. This appendix includes the following
sections:
"Resetting the Password Jumper" on page 180
"Clearing and Resetting the CMOS" on page 181
This workstation supports security password features, which can be established through the Computer
Setup Utilities menu. These features are:
setup password
power-on password
When you establish only a setup password, the power-on password is required to access Computer
Setup and any other information on the workstation. When you establish both passwords, only the setup
password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on password
as an override to log in to the workstation. This is a useful feature for a network administrator.
If you forget the password for the computer, there are two method for clearing that password so you can
gain access to the information on the workstation:
resetting the password jumper
using the Clear CMOS button
CAUTION Pushing the CMOS button resets CMOS values to factory defaults and erases any
customized information including passwords, asset numbers, and special settings. It is important to back
up the workstation CMOS settings before resetting them in case they are needed later. To back up the
CMOS settings, use Computer Setup and run the Save to Diskette option from the File menu.
