This package updates the basic input/output system (BIOS) on ThinkCentre A58 and M58e systems.

Note: This BIOS update is NOT for ThinkCentre A58 (type 5441, 5473, 5597 and 5894)

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.
