Startup Menu / F10 Setup BIOS Flashing
The HP Business Desktop systems provide a BIOS upgrade option through both the Startup Menu and the F10 Setup utility using the "Flash System ROM" feature. Reboot the PC and press the Escape key to display the Startup Menu. Use the arrow keys to select Utilities, and then select the Flash System ROM option. Alternatively, reboot the PC and press F10 to access the BIOS Setup utility. In the File menu, select Flash System ROM. Either method requires that removable media be present (USB storage or data CD) that contains the BIOS binary image file in the root directory. The binary image file can be found in the DOS Flash folder and is namedxxx_MMmm.binwhere "xxx" is the BIOS family, "MM" is the major version number, and "mm" is the minor version number. To create a CD for updating the BIOS, use a blank CD-R or CD-RW disk on a system with a CD-RW or DVD+RW drive, and write the binary to the disk using any CD-burning software (Windows 7 and Vista support burning data CDs without additional software). If a BIOS Setup password has been set, the password will be required before being able to access the "Flash System ROM" menu. The user is notified when the process is completed. The new BIOS code will not take effect until the PC is restarted.
