Flash BIOS update - bootable diskette version
for ThinkCentre A35 8139-21G and 8139-A1G systems
Version F2
Installation README


This package updates the basic input/output system (BIOS) on
ThinkCentre A35 8139-21G and 8139-A1G 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.
