+ ControllerHandle - The handle of a controller that the driver specified by

+ that that the caller is requesting, and it must match one
+ of the languages specified in SupportedLanguages. The

+ DiskIo.c
+
+Abstract:
+
+ DiskIo driver that layers it's self on every Block IO protocol in the system.
+ DiskIo converts a block oriented device to a byte oriented device.
+
+ ReadDisk may have to do reads that are not aligned on sector boundaries.
+ There are three cases:
+
+ UnderRun - The first byte is not on a sector boundary or the read request is
+ less than a sector in length.
+
+ Aligned - A read of N contiguous sectors.
+
+ OverRun - The last byte is not on a sector boundary.

+ Routine Description:
+ Read BufferSize bytes from Offset into Buffer.
+
+ Reads may support reads that are not aligned on
+ sector boundaries. There are three cases:
+
+ UnderRun - The first byte is not on a sector boundary or the read request is
+ less than a sector in length.
+
+ Aligned - A read of N contiguous sectors.
+
+ OverRun - The last byte is not on a sector boundary.
+
+
+ Arguments:
+ This - Protocol instance pointer.
+ MediaId - Id of the media, changes every time the media is replaced.
+ Offset - The starting byte offset to read from.
+ BufferSize - Size of Buffer.
+ Buffer - Buffer containing read data.
+
+ Returns:
+ EFI_SUCCESS - The data was read correctly from the device.
+ EFI_DEVICE_ERROR - The device reported an error while performing the read.
+ EFI_NO_MEDIA - There is no media in the device.
+ EFI_MEDIA_CHNAGED - The MediaId does not matched the current device.
+ EFI_INVALID_PARAMETER - The read request contains device addresses that are not
+ valid for the device.
