This package provides the ISO image file of BIOS which are compatible with CD/DVD writing software to create the CD/DVD for the BIOS update. Hereafter the CD/DVD for the BIOS update is called as "BIOS Update CD".
The BIOS Update CD can boot the computer disregarding the operating systems and update two sets of the BIOS (including system programs and Embedded Controller program) stored in the ThinkPad computers to fix problems, add new functions, or expand functions as noted below.
For that purpose, it is necessary to have the CD/DVD writing software (with CD/DVD creation function from the ISO image file) prepared separately.
Also, any one of the following type of CD-RW, CD-RW & DVD Combo, DVD, DVD Multi or other optical drives should be prepared. (Hereafter these drives are called as "optical drive".)
