Updating System Program (BIOS) ------------------------------ Notes: - Remove the Power-on password prior to updating the BIOS in RDM (Remote Deployment Manager) environment or similar environment. - You need an AC adapter and a charged battery pack to update the 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 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 will automatically turn 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 BIOS Setup Utility menu will be displayed. If a password prompt appears, type the correct password. 10. Verify the BIOS Version. 11. Turn off the computer. Initializing System Program (BIOS) ---------------------------------- In some cases, it may be a good idea to try BIOS initialization when you have some troubles. To initialize the BIOS setups: 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 BIOS Setup Utility menu will be displayed. If you have set a supervisor password, the BIOS Setup Utility menu appears after you enters the password. 6.

Memory Map Information ---------------------- Reserved Area: The following conventional memory addresses are reserved by the system program (BIOS) and others. C0000-CFFFF : Reserved for Video BIOS D0000-D3FFF : Reserved for Option ROM of Ethernet (*1) DC000-DFFFF : Reserved for USB BIOS (*2) E0000-FFFFF : Reserved for System BIOS Notes: *1: This area becomes free by disabling the Internal Network Option ROM option under Config and Network in BIOS Setup Utility. This choice will disable PXE and WOL features. *2: This area becomes free by disabling the USB BIOS Support option under Config and USB in the BIOS Setup Utility. This choice does not affect using USB devices in Windows operating systems. Usable Area: The following memory address can be used by the memory manager such as EMM386. D4000-DBFFF Note: Certain addresses in this area will be reserved for CardBus Controllers or others by Operating Systems. The addresses vary and depend on the design of each Operating System. Switching external display -------------------------- BIOS video controller has been changed switching interface between LCD and external monitor from previous released models. Previous models' screen resolutions on both the LCD and external monitor could be set separately while the display output is switched between the LCD and external monitor. Latest update of specification, both the screen resolutions are to be fixed for a display device with larger screen resolutions. So if the external monitor has a larger screen resolution than the LCD has and when display output is switched to the LCD, the LCD will have the extended desktop screen.
