This package is for use with systems that are not AMT capable. 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.
