Power-On Password; Removing A Power-On Password; Administrator Password; Administrator Password Control - IBM NetVista Hardware Maintenance Manual

Power-on and Administrator passwords are set in the Setup Utility program. See
"Using the Configuration/Setup Utility program" on page 19 for information about
running the Setup Utility.

Power-on password

A power-on password denies access to the computer by an unauthorized user
when the computer is powered on. When a power-on password is active, the
password prompt appears on the screen each time the computer is powered on.
The computer starts after the proper password is entered.

Removing a power-on password

To service a computer with an active and unknown power-on password, power-off
the computer and use the following procedure.
1. Unplug the power cord and remove the top cover.
2. Refer to "System board layout" on page 39 to find the recovery jumper.
3. Move the recovery jumper from normal to clear.
4. Power-on the computer. The system senses the change in the position and
5. Remind the user to enter a new password when service is complete.

Administrator password

The administrator password is used to restrict access to the Configuration/Setup
Utility program. If the administrator password is activated, and you do not enter
the administrator password, the configuration can be viewed but not changed.

Administrator password control

The Administrator password is set in the Setup Configuration. Refer to "Using the
Configuration/Setup Utility program" on page 19.

Operating system password

An operating system password is very similar to a power-on password and denies
access to the computer by an unauthorized user when the password is activated.
The computer is unusable until the password is entered and recognized by the
computer.

Vital product data

Each computer has a unique Vital Product Data (VPD) code stored in the
nonvolatile memory on the system board. After you replace the system board, the
VPD must be updated. To update the VPD, see "Flash (BIOS/VPD) update
procedure" on page 74.

erases the password. It is necessary to move the jumper back to the previous position.
Note:
Type 6838, 6848 computers have Enhanced Security Mode. If Enhanced Security mode is
enabled and there is no password given, the computer will act as if Enhanced Security is
disabled.
If Enhanced Security is Enabled and an administrator password is given, the administrator
password must be entered to use the computer. If the administrator password is lost or
forgotten, the system board in the computer must be replaced in order to regain access to
the Configuration/Setup Utility program.
