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).
- If your computer is attached to any kind of docking station or port replicator, turn off the computer and detach it before proceeding.
- Make sure the System Program Service Diskette is write-protected.
- For Windows 98, 98SE users: The release 1RETDRWW (3.23) and later version will have special USB drive letter assigning and this will cause a limitation in the Windows 98/98SE drive letter assignment. Please use BIOS 1RETDRWW (3.21), if you use USB storage devices on Windows 98/98SE.
