This library identifies the firmware boot media device.
|
|
The firmware boot media device is used to make system initialization decisions in the boot flow dependent
|
upon firmware boot media. Note that the firmware boot media is the storage media that the boot firmware is stored on.
|
It is not the OS storage media which may be stored upon a different non-volatile storage device.
