1 /** @file 2 This file declares the hardware-device class GUIDs that may be used by the 3 PEIM that produces the Virtual Block I/O PPI. 4 5 These GUIDs are hardware-device class GUIDs that would be imported only by the 6 Virtual Block I/O PEIM. This virtual PEIM imports only the actual Block I/O 7 PPIs from the device-class ones listed here and published a single instance of 8 the Block I/O PPI for consumption by the File System PEIM. In the parlance of 9 the Framework DXE software stack, this Virtual Block I/O PEIM is actually 10 embodying the functionality of the partition driver. Thsi Virtual Block I/O 11 PEIM has to multiple the multiple possible instances of Block I/O and also know 12 how to parse at least El Torito for CD-ROM, and perhaps Master Boot Record(MBR) 13 and GUID Partition Table(GPT) in the future. 14 15 Copyright (c) 2009 - 2010, Intel Corporation.
