Updating System Program (BIOS)
------------------------------
Notes:
- Remove the Power-on password prior to updating the system program
  (BIOS) in RDM (Remote Deployment Manager) environment or similar
  environment.
- You need an AC adapter and a charged battery pack to update the
  system program (BIOS).
- Make sure the System Program Service Diskette is write-protected.

 1. Print these instructions or display on another computer.
 2. Firmly connect the AC adapter to the computer.
 3. Start Microsoft Windows 2000/XP and logon with administrative 
    privileges on the target computer.
 4. Make the temporary directory on the hard disk drive 
    (for instance, C:\Temp)
 5. Download the ThinkPad BIOS Update Utility from the web site and 
    store the file into the temporary directory.
 6. Click Start and then click Run.
 7. In the Open dialog box, specify the utility filename with the full 
    path name where you stored ThinkPad BIOS Update Utility. 
    (For example: C:\Temp\1xuj04ud.exe) 
    Then click OK. This will create the diskette.
 8. Insert the write protected System Program Service Diskette into
    the diskette drive and turn on the computer.
 9. Select Read this first from the menu and carefully read the
    information that appears.
10. Press the Esc key to return to the menu.
11. Select Update system program and follow the instructions on the
    screen.

    Note:
    If you are updating the system program through the USB external
    diskette drive, it will take quite a long time to complete reading
    the system program file, but it is normal. Continue the update.

    Attention:
    Do not turn off, suspend the computer or remove the diskette until
    the update has been completed. IF YOU TURN OFF OR SUSPEND THE
    COMPUTER WHILE THE UPDATE IS STILL IN PROGRESS, THE SYSTEM BOARD
    MAY HAVE TO BE REPLACED.

 After the update has been completed, the system is automatically
