IBM ThinkPad X31 April 28, 2003 System Program Service Diskette BIOS Version : 1QET34WW (1.03) Diskette Version : 1.03 ====================================================================== Notice: ------- - This BIOS version will only work with Embedded Controller Program Version 1.01 (or higher). Please get an additional package, Embedded Controller Program Version 1.01 (or higher), and update Embedded Controller Program in the system with it if necessary. - If you should update Embedded Controller Program as well as the BIOS, update Embedded Controller Program first. - This program is language independent and can be used with any language system. What This Diskette Does ----------------------- This System Program Service Diskette updates the system program (BIOS) stored in the ThinkPad system to fix problems, add new functions, or expand functions as noted below. This release supports the following system: - ThinkPad X31 To determine if you should update the system program, refer to the Summary of Changes section. To update the system program, refer to the Updating System Program (BIOS) section. Released Versions ----------------- Where: - Diskette version - BIOS version (BIOS internal ID) 1.00b - 1.00b (1QET31WW) Initial Release for ThinkPad X31 1.01 - 1.01 (1QET32WW) Problem fixes 1.02 - 1.02 (1QET33WW) Problem fixes 1.03 - 1.03 (1QET34WW) A function enhancement and problem fixes Summary of Changes ------------------ Where: n.nn : Diskette version x.xx : BIOS version bbbbbbbb : BIOS internal ID which is for administrator purpose. (New) New Function or Enhancement (Fix) Correction to existing function <1.00b - 1.00b (1QET31WW)> NOTE: This BIOS version will only work with Embedded Controller Program Version 1.01 (or higher). - (New) Support for ThinkPad X31. <1.01 - 1.01 (1QET32WW)> NOTE: This BIOS version will only work with Embedded Controller Program Version 1.01 (or higher). - (New) The design of Access IBM Predesktop Area screen, which is shown after pressing the "Access IBM" button, is changed to prevent the system from going into suspend or hibernation mode. (This is to avoid some problems.) - (Fix) On the model with IBM Security Chip installed, selecting some items in IBM BIOS Setup Utility may cause system hang if the IBM Security Chip option in IBM BIOS Setup Utility is set to Enabled. - (Fix) Some of the memory controller settings are changed. <1.02 - 1.02 (1QET33WW)> NOTE: This BIOS version will only work with Embedded Controller Program Version 1.01 (or higher). - (New) Pressing F11 key at power-on time can run IBM Product Recovery program, as well as pressing the Access ThinkPad button. - (Fix) (Windows 98) If the system goes into suspend or hibernation mode while it accesses the HDD so often, resuming normal operation from the mode may fail. - --- Processor family value in SMBIOS for Intel Pentium M processor is changed. <1.03 - 1.03 (1QET34WW)> NOTE: This BIOS version will only work with Embedded Controller Program Version 1.01 (or higher). - (New) Function to disable the option ROM of internal Ethernet adapter card, in order to expand usable memory area by DOS. (This can be done by disabling the Internal Network Option ROM option under Config and Network in IBM BIOS Setup Utility.) - (Fix) (DOS) The screen becomes blank or white when Korean DOS environment starts up (with loading mshbios.com). - (Fix) Screen expansion (HV expansion) is always enabled if a power- on password or hard disk password is set. - (Fix) Some of Item Specific Help messages in IBM BIOS Setup Utility are incorrect. 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 port replicator, turn off the computer and detach it before proceeding. (Except the ThinkPad UltraBase X3 option. You can attach the option and use the diskette drive option in it.) - 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, not the diskette drive in the ThinkPad UltraBase X3), 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 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 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 F1 key. The IBM BIOS Setup Utility menu will be displayed. If a password prompt appears, type the correct password. 5. Press F9 key to load default configuration. 6. Select Yes. 7. Press F10 key to save default configuration and exit. 8. Select Yes. After the initialization has been completed, the system restarts automatically.
