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