Installation README


This package updates the basic input/output system (BIOS) on
3000 J100 (type 8255, 8256, 8456, 8457) and ThinkCentre E50
(type 8469, 8474, 8708, 8709, 8710, 8711, 8776, 8777, 8778, 8779)
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.
