REASON FOR CHANGE

To implement changes under "Details of Change."

IMPACT OF CHANGE

This system BIOS update is required for the HP EliteBook 8540p Notebook PC and the HP EliteBook 8540w Mobile Workstation, and it is required to support new Intel K-0 stepping processors. HP highly recommends users do not revert back to system BIOS versions earlier than F.0A. Flashing a BIOS version prior to F.0A after updating the BIOS version to F.0A will cause the system to not boot and will render the system board useless.
