Installation README


This package updates the basic input/output system (BIOS) on
ThinkCentre A53 (type 8701, 8702, 8970, 8973, 8980, 8983, 8992,
8995, 9276, 9277, 9286, 9287, 9378, 9387, 9628, 9635) systems.

BIOS is programming that controls low-level hardware operations,
including interactions with diskette drives, hard disk drives,
and the keyboard. The BIOS is stored on a chip. Your computer
uses flash BIOS, which can be updated through a program on a 
flash diskette so that you do not have to replace the BIOS
chip to update the BIOS.

Note: Make note of any settings you have changed in the BIOS
Configuration Utility. These settings may have to be re-entered
after updating the BIOS.
