-Module Name:
-
- BlockIo.h
-
-Abstract:
-
- Block IO protocol as defined in the EFI 1.0 specification.
-
- The Block IO protocol is used to abstract block devices like hard drives,
- DVD-ROMs and floppy drives.

- RemovableMedia - TRUE if the media is removable; otherwise, FALSE.
- MediaPresent - TRUE if there is a media currently present in the device;
- othersise, FALSE. THis field shows the media present status
- as of the most recent ReadBlocks() or WriteBlocks() call.
- LogicalPartition - TRUE if LBA 0 is the first block of a partition; otherwise
- FALSE. For media with only one partition this would be TRUE.
- ReadOnly - TRUE if the media is marked read-only otherwise, FALSE. This
- field shows the read-only status as of the most recent
- WriteBlocks () call.
- WriteCaching - TRUE if the WriteBlock () function caches write data.
- BlockSize - The intrinsic block size of the device. If the media changes, then
- this field is updated.
- IoAlign - Supplies the alignment requirement for any buffer to read or write
- block(s).
- LastBlock - The last logical block address on the device. If the media changes,
- then this field is updated.
