  1. Download the flash file from the Hewlett Packard support site (http://www.hpe.com/info/hpesc).
    After finding your server, set the filter to Independent OS to display ROM files.
  2. Copy the file to a USB or iLO virtual media.
  3. Attach the media to the server.
    If updating remotely through iLO, attach the media to your workstation.
  4. Boot the server to System Utilities > Embedded Applications > Embedded UEFI Shell.
    The UEFI Shell screen appears.
  5. Press any key to acknowledge that you are physically present.

  6. If an administrator password is set, enter the password, and then press Enter.
    The Shell> prompt is displayed.
  7. Display the file system mappings, and then get the file system volume name for the USB or virtual media. 
    Shell>map -r
    The mapping table is displayed.
  8. Change the working directory to the USB or virtual media.
    For example, if the USB volume name is FS0:, then enter 
    Shell>FS0:
  9. List the devices in the server with firmware. 
    FS0:\>fwupdate -l
  10. Flash the firmware. 
    FS0:\>fwupdate –d BIOS -f <filename>
    You can press the TAB key to complete the filename.

The installation is complete.
