Revision : 01 -------------------------------------------------------------------------------- Software name BIOS Update CD (ISO image file for bootable CD) Support models ThinkPad T420, T420i Operating Systems Microsoft Windows 8 32-bit, 64-bit Microsoft Windows 7 32-bit, 64-bit Microsoft Windows Vista 32-bit, 64-bit Microsoft Windows XP Professional SP3 Refer to marketing materials to find out what computer models support which Operating Systems. Version 1.52 -------------------------------------------------------------------------------- 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, any one of the following types 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".) - ThinkPad internal - USB This program is language independent and can be used with any language system. -------------------------------------------------------------------------------- CHANGES IN THIS RELEASE Version 1.52 [Important updates] - Security fix addresses LEN-22133 Speculative Execution Side Channel Variants 4 and 3a (CVE-2018-3639, CVE-2018-3640).
