Note:
Your computer has Enhanced Security Mode. If Enhanced Security mode is enabled and
there is no password set, the computer will act as if Enhanced Security is disabled.
If Enhanced Security is Enabled and an administrator password is set, 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 IBM Setup Utility program.
Administrator password control
The Administrator password is set in the IBM Setup Utility program. Refer to
Chapter 5, “IBM 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 update procedures” on page
113.
BIOS levels
An incorrect level of BIOS can cause false errors and unnecessary FRU
replacement. Use the following information to determine the current level of BIOS
installed in the computer, the latest BIOS available for the computer, and where to
obtain the latest level of BIOS.
v Current Level BIOS information
– Run the IBM Setup Utility program to determine the level of BIOS installed.
