c9a4a977 1/** @file\r
2 This file declares the hardware-device class GUIDs that may be used by the \r
3 PEIM that produces the Virtual Block I/O PPI.\r
4\r
5 These GUIDs are hardware-device class GUIDs that would be imported only by the\r
6 Virtual Block I/O PEIM. This virtual PEIM imports only the actual Block I/O \r
7 PPIs from the device-class ones listed here and published a single instance of\r
8 the Block I/O PPI for consumption by the File System PEIM. In the parlance of\r
9 the Framework DXE software stack, this Virtual Block I/O PEIM is actually \r
10 embodying the functionality of the partition driver. Thsi Virtual Block I/O\r
11 PEIM has to multiple the multiple possible instances of Block I/O and also know\r
f22f941e 12 how to parse at least El Torito for CD-ROM, and perhaps Master Boot Record(MBR)\r
c9a4a977 13 and GUID Partition Table(GPT) in the future.\r
