This program is language independent and can be used with any language system. ---------------------------------------------------------------------- CHANGES IN THIS RELEASE [Important Updates] Nothing. [New functions or enhancements] Nothing. [Problem fixes] - A CardBus Controller setting was wrong. - The computer may hang up when a boot device is changed in Startup menu of BIOS Setup Utility. ---------------------------------------------------------------------- DETERMINING WHICH VERSION IS INSTALLED There are two ways for version check. (A) On Windows (B) On BIOS Setup Utility (A) On Windows 1. Start the ThinkPad Configuration program. Click Start, select All Programs (or Programs), select ThinkVantage, and then click ThinkPad Configuration. 2. Click the System Information icon. 3. Click the BIOS information tab. BIOS version and Embedded Controller version will be displayed. 4. Click OK to exit. (B) On BIOS Setup Utility 1. Turn off the computer. 2. Turn on the computer. 3. 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 F1 key. The BIOS Setup Utility menu will be displayed. If a password prompt appears, type the correct password. 4. Check BIOS Version and Embedded Controller Version. 5. Turn off the computer. ---------------------------------------------------------------------- NOTES - This BIOS version will only work with Embedded Controller Program Version 1.01 (or higher). Obtain the additional package, Embedded Controller Program Version 1.01 (or higher), and update the Embedded Controller Program in the system with it. - If you need to update Embedded Controller Program as well as the BIOS, update BIOS first. ---------------------------------------------------------------------- UPDATE INSTRUCTIONS Notes: - If your computer runs satisfactorily now, it may not be necessary to update the BIOS. 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) environment or similar environment. 1. Firmly connect the AC adapter to the computer. 2. Insert the write protected System Program Service Diskette into the diskette drive and turn on the computer. 3. Select Read this first from the menu and carefully read the information that appears. 4. Press the Esc key to return to the menu. 5. Select Update system program and follow the instruction 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. 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. ---------------------------------------------------------------------- INITIALIZING BIOS BIOS Initialization is suggested for some problems. To initialize the BIOS settings: 1. Turn off the computer. 2. Turn on the computer. 3.
