  ** Notes in general **

  * Refer to "license_en.txt" about the user license agreement.

  * When Windows(R) BitLocker(TM) function is set to "Enabled", install the
    System ROM after making the function "Disabled". Then make the function
    "Enabled" after install and reboot of the system. If you install the system
    ROM without making the function "Disabled", you may need the recovery
    password when you boot the system.

  * To meet firmware dependencies, you can update iLO7 firmware by latest
    Starter Pack. 
    You can download latest update module(s) from the following web site.
