3.6 BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on

the Intel World Wide Web site:

• Intel® Express BIOS Update utility, which enables automated updating while in the

Windows environment. Using this utility, the BIOS can be updated from a file on a

hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from

the file location on the Web.

• Intel® Flash Memory Update Utility, which requires booting from DOS. Using this

utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash

drive or a USB hard drive), or a CD-ROM.

Both utilities verify that the updated BIOS matches the target system to prevent

accidentally installing an incompatible BIOS.



NOTE

Review the instructions distributed with the upgrade utility before attempting a BIOS

update.
