Version 2.24 -------------------------------------------------------------------------------- WHAT THIS PACKAGE DOES This package provides the ISO image file of UEFI BIOS which is compatible with CD/DVD/BD writing software to create the CD/DVD/BD for the UEFI BIOS update. Hereafter the CD/DVD/BD for the UEFI BIOS update is called as "BIOS Update CD". The BIOS Update CD can boot the computer disregarding the operating systems and update the UEFI BIOS (including system program and Embedded Controller program) stored in the ThinkPad computer to fix problems, add new functions, or expand functions as noted below. For that purpose, it is necessary to have the CD/DVD/BD writing software (with CD/DVD/BD creation function from the ISO image file) prepared separately. Also, the following type of CD-RW, CD-RW & DVD Combo, DVD, DVD Multi, BD or other optical drives should be prepared. (Hereafter these drives are called as "optical drive".) - USB This program is language independent and can be used with any language system. -------------------------------------------------------------------------------- CHANGES IN THIS RELEASE Version 2.24 [Important updates] - Security fix addresses LEN-8324 System Management Mode (SMM) BIOS Vulnerability and some security fixes. (Note) If the UEFI BIOS has been updated to version 2.24 or higher, it is no longer able to roll back to the version before 2.24 for security improvement. [New functions or enhancements] - Updated the Diagnostics module to version 2.09.09. - Updated the CPU microcode.

To use it, change the option to Enabled. (The UEFI BIOS version 2.11 or lower enabled it.) - In case that your computer has been registered by ThinkVantage Hardware Password Manager with the UEFI BIOS version 2.09 (GMET61WW) or earlier, you should deregister your computer from ThinkVantage Hardware Password Manager before updating the UEFI BIOS to version 2.10 (GMET62WW) or higher. Consult your IT administrator or the manual of ThinkVantage Hardware Password Manager about how to deregister the computer. - Be aware that the OS Optimized Defaults option in the Restart menu of ThinkPad Setup should not be normally changed. Lenovo recommends to use the factory default setting for it, as follows. OS Optimized Defaults - For Windows 10/8.1/8 64-bit Preload models [Enabled] - For Windows 7 [Disabled] To install Windows 7, the OS Optimized Defaults option should be [Disabled]. If the OS Optimized Defaults setting is changed, Setup Default by the F9 key will not load the same default configuration, as follows. Furthermore, by the condition of Operating System installation, the computer may not be booted due to the setting change. If your computer runs satisfactorily now, you have no need to change the OS Optimized Defaults option. If you need to change the setting, consider well the effect of the setting change. Affected Setup menu items : "OS Optimized Defaults" setting [Disabled] case [Enabled] case - Security - UEFI BIOS Update Option - Secure RollBack Prevention [Disabled] [Enabled] - Secure Boot - Secure Boot [Disabled] [Enabled] - Startup - UEFI/Legacy Boot [Both] [UEFI Only] - UEFI/Legacy Boot Priority [Legacy First] (Not shown) - CSM Support [Yes] [No] By the OS to be newly installed, you need to change the OS Optimized Defaults option, and load default configuration. 1. Enter the ThinkPad Setup menu by following steps in [Checking On ThinkPad Setup] in the DETERMINING WHICH VERSION IS INSTALLED section. 2. Select Restart, then select OS Optimized Defaults and press Enter. 3. Select the following setting and press Enter. [Enabled] (for Windows 10/8.1/8 64-bit) [Disabled] (for Windows 7) 4. Press the F9 key to load default configuration. 5. Select Yes. 6. Press the F10 key to save default configuration and exit. 7. Select Yes. The computer will be restarted automatically. - Lenovo recommends to install the USB 3.0 driver for Windows (Version 1.0.4.225 or higher) prior to updating the UEFI BIOS. Because the UEFI BIOS requires the modification in the USB 3.0 driver to fix USB 3.0 related issues. (Caution) If both the Secure Boot option is Enabled and UEFI Secure Boot in the Main menu of ThinkPad Setup is shown as Off, restoring Factory Keys is needed. Do the following to restore Factory Keys. 1. Enter the ThinkPad Setup menu by following steps in [Checking On ThinkPad Setup] in the DETERMINING WHICH VERSION IS INSTALLED section. 2.
