Attention
This procedure will remove the administrator password. Also, this procedure
will clear all setup parameters, privilege access, and boot sequence settings.
Make sure these setting are recorded before performing this procedure.
1. Unplug the power cord and remove the top cover.
2. Refer to “System Board Layout” on page H-6 to find the password jumper.
3. Move the password jumper to connect the center pin and the pin on the
opposite end of the connector.
4. Power-on the computer. The system senses the change in the position and
erases the password.
¹
It is necessary to move the jumper back to the previous position.
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.
Note
Type 6563 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.
Administrator Password Control
The Administrator password is set in the Setup Configuration. Refer to “Service
Processor Configuration / Setup Utility” on page H-9
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 3-34.
