Version 1.58 -------------------------------------------------------------------------------- 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 1.58 [Important updates] - Enhancement to address security vulnerability, CVE-2022-34301, CVE-2022-34302, CVE-2022-34303 [New functions or enhancements] - Updated the Diagnostics module to version 04.27.000. [Problem fixes] - Fixed an issue where CPU clock may become low after resuming from sleep state, if Intel PTT is disabled in BIOS Setup. - Fixed an issue where system does not wake up from sleep state by User Presence Detection. - Fixed an issue where system may hang at POST if Fingerprint Reader function is disabled in BIOS Setup. -------------------------------------------------------------------------------- DETERMINING WHICH VERSION IS INSTALLED There are two ways to check the UEFI BIOS version and BIOS ID.
