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 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. 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. 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 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 F9 key to load default configuration. 7. Select Yes. 8. Press F10 key to save default configuration and exit. 9. Select Yes. NOTES: - After initialization you may need to re-apply some settings that you had changed previously. - After the initialization has been completed, the system restarts automatically. BIOS Information ---------------- Each version of the System Program Service Diskette contains the following system program (BIOS). Also the supported versions of Embedded Controller Program are shown bellow. The versions of BIOS and Embedded Controller Program can be viewed by entering IBM BIOS Setup Utility.

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. 4. Double-click Start setup utility. The IBM BIOS Setup Utility menu will be displayed. If a password prompt appears, type the correct password. 5. Check BIOS Version and Embedded Controller Version. 6. Turn off the computer. 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 (Note) *1: This area becomes free by disabling the Internal Network Option ROM option under Config and Network in IBM 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 IBM BIOS Setup Utility. This choice does not affect using USB devices in Windows system. Usable Area: The following memory address can be used by the memory manager such as EMM386. D4000-DBFFF But 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. Startup Menu ------------ Please check the order specified in the Boot and/or Network submenu. You may need to change the startup sequence of your computer. For example, if you have different operating systems on different devices, you can have the system start up from one of them. WARNING: After you change your startup sequence, you must be extremely careful not to specify a wrong device during a copy, a save, or a format operation. If you specify a wrong device, your data and programs might be erased or overwritten. - Changing the startup sequence NOTE: To change the startup sequence temporarily so that the system starts up from a different drive, do the following. When the message, "To interrupt normal startup, press the blue Access IBM button," appears at lower left on the screen, press F12. To change the startup sequence, do the following: 1. Click Boot or Network; then press Enter. 2. The Boot submenu sets the startup sequence when you turn the power switch on. Refer to "Boot submenu." 3. Select the device you want to start first. 4. Use these keys to set the order that the BIOS will use when starting an operating system: F6/F5: Move the device up or down. x: Exclude or include the device to boot. 1: Load the default boot sequence. 5. Press F10 to save the changes and restart the system. - The Boot submenu NOTES: - On your computer, the items listed in the submenu may be different from those shown in the example listing here. Your list shows the devices that are attached to your computer. - Each device type in the list above is always shown whether or not it is installed or attached. If a device is attached, the actual device information will be shown to the right of the device type. - ATAPI CD0 refers to an optical drive installed in the UltraBay Slim/Enhanced bay. - IDE HDD0 refers to the primary hard disk drive. - IDE HDD1 refers to a second hard disk drive installed in the UltraBay Slim/Enhanced. - PM : Primary Master - SM : Secondary Master Example listing: Boot priority order: <-- Startup devices candidate group 1: USB FDD: 2: ATAPI CD0: 3: USB CD: 4: IDE HDD0: 5: PCI LAN: 6: USB HDD: 7: IDE HDD1: Excluded from boot order: <-- Not to be startup devices group. : IDE HDD2: : ATAPI CD1: Priority for booting USB devices If you attach two or more USB devices of the same type to the computer (for example, two USB CD-ROM drives or two USB diskette drives), the computer starts the devices in accordance with the boot priority order specified for the USB connectors. If you are attaching your computer to a ThinkPad Dock II or a ThinkPad Mini Dock, the boot priority order for the USB connectors is as follows: 1. USB connector1 on the ThinkPad Dock II or the ThinkPad Mini Dock 2. USB connector2 on the ThinkPad Dock II or the ThinkPad Mini Dock 3. USB connector3 on the ThinkPad Dock II or the ThinkPad Mini Dock 4. USB connector4 on the ThinkPad Dock II or the ThinkPad Mini Dock 5. Lower USB connector on the ThinkPad computer 6.
