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). - 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. 1. Print these instructions or display on another computer. 2. Firmly connect the AC adapter 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 instruction on the screen. NOTE: If you are updating the system program through the external diskette drive (USB type), it will take quite a long time to complete reading the system program file, but it is normal. Continue the update. Warning: 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 turned off. Do the following to make sure the BIOS is updated correctly. 7. Make sure there is no diskette in the diskette drive, then turn on the computer. 8. While the "To interrupt normal startup, press the blue Access IBM button" message is displayed at the lower-left area of the screen, press the Access IBM button. 9. Double-click Start setup utility. The IBM BIOS Setup Utility menu will be displayed. If you have set a supervisor password, the IBM BIOS Setup Utility menu appears after you enters the password. 9. Verify the BIOS Version. 10. Turn off the computer. Initializing System Program (BIOS) ---------------------------------- In some cases, it may be a good idea to try BIOS initialization when you are having a problem. To initialize the BIOS settings: 1. Turn off the computer. 2. Make sure there is no diskette in the diskette drive. 3. Turn on the computer. 4. While the "To interrupt normal startup, press the blue Access IBM button" message is displayed at the lower-left area of the screen, press the Access IBM button. 5. Double-click Start setup utility. The IBM BIOS Setup Utility menu will be displayed. If you have set a supervisor password, the IBM BIOS Setup Utility menu appears after you enters the password. 6. Press the F9 key to load default configuration. 7. Select Yes. 8. Press the F10 key to save default configuration and exit. 9. Select Yes. After the initialization has been completed, the system restarts automatically.
