This package updates the basic input/output system (BIOS) on ThinkCentre A52 (type 8153, 8154, 8155, 8156, 8157, 8158, 8159, 8160, 8161, 8162, 8163, 8164, 8165, 8166, 8167, 8168, 8169, 8170) and ThinkCentre M52 (type 8099, 8110, 8111, 8112, 8113, 8114, 8115, 8116, 8211, 8212, 8213, 8214, 8215, 9210, 9211) 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.
