Updating BIOS on systems with bitlocker enabled
CAUTION: If BitLocker is not suspended before updating the BIOS, the next time you reboot the system
it will not recognize the BitLocker key. You will then be prompted to enter the recovery key to progress
and the system will ask for this on each reboot. If the recovery key is not known this can result in
data loss or an unnecessary operating system re-install. For more information on this subject, please
