This chapter tells you how to update the BIOS by either using the Intel Express BIOS Update utility
or the Iflash 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 D945GCZ 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.
