To determine if you should update the BIOS, refer to the Version Information section. - 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. - Remove the Power-on password prior to updating the system program (BIOS) in RDM (Remote Deployment Manager) or similar environment. Attention: Do not turn off, suspend the computer or remove the diskette until the update has been completed. IF YOU DO THAT WHILE THE UPDATE IS STILL IN PROGRESS, THE SYSTEM BOARD MAY HAVE TO BE REPLACED. 1. Firmly connect the AC adapter to the computer. 2. Make sure an diskette drive is attached to the computer. 3. Insert the write protected System Program Service Diskette into the diskette drive and turn on the computer. 4. Select Read this first from the menu and carefully read the information that appears. 5. Press the Esc key to return to the menu. 6. 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. After the update has been completed, the system is automatically turned off. ---------------------------------------------------------------------- INITIALIZING BIOS BIOS Initialization is suggested for some problems.
