1. Go to the Intel World Wide Web site: http://support.intel.com/support/motherboards/desktop/ 2. Navigate to the D845HV or D845WN page and click the Express BIOS Update utility file for the D845HV or D845WN board’s BIOS. 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.)
Flash Memory Update Utility With the Intel Flash Memory 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.
Updating the BIOS Recovering the BIOS It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails. The following procedure uses recovery mode for the Setup program. See page 37 for more information on Setup modes.
