3 Updating the BIOS

This chapter tells you how to update the BIOS by either using the Intel Express BIOS Update
utility or the Intel

®

Flash Memory Update Utility, and how to recover the BIOS if an update fails.

Updating the BIOS with the Intel

®

Express BIOS Update

Utility

With the Intel Express BIOS Update utility you can update the system BIOS while in the
Windows* environment. The BIOS file is included in an automated update utility that combines
the functionality of the Intel Flash Memory Update Utility and the ease-of use of Windows-based
installation wizards.

To update the BIOS with the Intel Express BIOS Update utility:

1. Go to the Intel World Wide Web site:

http://support.intel.com/support/motherboards/desktop/

2. Navigate to the D845GLVA page, click “[

view

] Latest BIOS updates”, and select the

Express BIOS Update utility file.

3. Download the file to your hard drive. (You can also save this file to a diskette. This is useful

if you are updating the BIOS for multiple identical systems.)

4. Close all other applications. This step is required. Your system will be rebooted at the last

Express BIOS Update window.

5. Double-click the executable file from the location on your hard drive where it was saved. This

runs the update program.

6. Follow the instructions provided in the dialog boxes to complete the BIOS update.

Updating the BIOS with the Intel

®

Iflash BIOS Update

Utility

With the Intel

®

Iflash BIOS update utility you can update the system BIOS from a floppy disk or

other bootable media. The utility available from the Web provides a simple method for creating a
bootable flash memory update floppy that will automatically update your BIOS.

Obtaining the BIOS Update File

You can update to a new version of the BIOS by using the BIOS update file. The BIOS update file
is a compressed self-extracting archive that contains all the files you need to update the BIOS. The
BIOS update file contains:

•

New BIOS files

•

BIOS recovery files

•

Intel Flash Memory Update Utility

You can obtain the BIOS update file through your computer supplier or by navigating to the
D845GLVA page on the Intel World Wide Web site at:

http://support.intel.com/support/motherboards/desktop/
