What if the ME firmware does not complete the update process? The ME retains a recovery image of the current firmware during the update process. If for any reason the ME cannot successfully complete the update, the ME will continue to function properly with the current firmware image. Can the ME firmware be restored to a previous version after updating? The ME firmware cannot be regressed to a previous version after successfully completing the update process. The ME firmware can only be updated to a newer image. Summary HP's Business PC BIOS provides update methods to allow the user or administrator to manage the BIOS upgrades and ME firmware in a flexible manner. HPQFlash offers a familiar, Windows application interface that allows the user to confidently update the BIOS and processor microcode. Setup-based-flash and recovery provides a convenient, local upgrade method which is not dependent on the PC operating system. The Flashbin utility provides a traditional DOS upgrade operation for local or remote situations. Administrators can use the remote management capabilities of such tools as SSM and Altiris to deliver enterprise wide upgrade ability. Regardless of the BIOS flash method, business PC products provide a high degree of upgrade reliability and offer failure safe recovery. We are confident that HP will remain the premier provider of comprehensive BIOS upgrade solutions in the industry.
