for ThinkCentre(R) 8086, 8087, 8088, 8089, 8090, 8092
Version 2DKT12A
Installation README


This package updates the basic input/output system (BIOS) on
ThinkCentre 8086, 8087, 8088, 8089, 8090, and 8092 systems.

BIOS is programming that controls low-level hardware operations,
including interactions with diskette drives, hard 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.
