/** @file
|
||
|
|
This file declares the hardware-device class GUIDs that may be used by the
|
||
|
|
PEIM that produces the Virtual Block I/O PPI.
|
||
|
|
|
||
|
|
These GUIDs are hardware-device class GUIDs that would be imported only by the
|
||
|
|
Virtual Block I/O PEIM. This virtual PEIM imports only the actual Block I/O
|
||
|
|
PPIs from the device-class ones listed here and published a single instance of
|
||
|
|
the Block I/O PPI for consumption by the File System PEIM. In the parlance of
|
||
|
|
the Framework DXE software stack, this Virtual Block I/O PEIM is actually
|
||
|
|
embodying the functionality of the partition driver. Thsi Virtual Block I/O
|
||
|
|
PEIM has to multiple the multiple possible instances of Block I/O and also know
|
||
|
|
how to parse at least El Torito for CD-ROM, and perhaps Master Boot Record(MBR)
|
||
|
|
and GUID Partition Table(GPT) in the future.
