| 2 | SMM Fault Tolerant Write protocol is related to EDK II-specific implementation of FTW,
|
|---|
| 3 | provides boot-time service for fault tolerant write capability for block devices in
|
|---|
| 4 | EFI SMM environment. The protocol provides for non-volatile storage of the intermediate
|
|---|
| 5 | data and private information a caller would need to recover from a critical fault,
|
|---|
| 6 | such as a power failure.
