Disk I/O 2 protocol as defined in the UEFI 2.4 specification.
The Disk I/O 2 protocol defines an extension to the Disk I/O protocol to enable non-blocking / asynchronous byte-oriented disk operation.

| typedef EFI_STATUS(EFIAPI * EFI_DISK_CANCEL_EX) (IN EFI_DISK_IO2_PROTOCOL *This) |
Terminate outstanding asynchronous requests to a device.
| This | Indicates a pointer to the calling context. |
| EFI_SUCCESS | All outstanding requests were successfully terminated. |
| EFI_DEVICE_ERROR | The device reported an error while performing the cancel operation. |
| typedef EFI_STATUS(EFIAPI * EFI_DISK_FLUSH_EX) (IN EFI_DISK_IO2_PROTOCOL *This, IN OUT EFI_DISK_IO2_TOKEN *Token) |
Flushes all modified data to the physical device.
| This | Indicates a pointer to the calling context. |
| MediaId | ID of the medium to be written. |
| Token | A pointer to the token associated with the transaction. If this field is NULL, synchronous/blocking IO is performed. |
| EFI_SUCCESS | If Event is NULL (blocking I/O): The data was flushed successfully to the device. If Event is not NULL (asynchronous I/O): The request was successfully queued for processing. Event will be signaled upon completion. |
| EFI_WRITE_PROTECTED | The device cannot be written to. |
| EFI_DEVICE_ERROR | The device reported an error while performing the write operation. |
| EFI_NO_MEDIA | There is no medium in the device. |
| EFI_MEDIA_CHNAGED | The MediaId is not for the current medium. |
| EFI_OUT_OF_RESOURCES | The request could not be completed due to a lack of resources. |

| typedef EFI_STATUS(EFIAPI * EFI_DISK_READ_EX) (IN EFI_DISK_IO2_PROTOCOL *This, IN UINT32 MediaId, IN UINT64 Offset, IN OUT EFI_DISK_IO2_TOKEN *Token, IN UINTN BufferSize, OUT VOID *Buffer) |
Reads a specified number of bytes from a device.
| This | Indicates a pointer to the calling context. |
| MediaId | ID of the medium to be read. |
| Offset | The starting byte offset on the logical block I/O device to read from. |
| Token | A pointer to the token associated with the transaction. If this field is NULL, synchronous/blocking IO is performed. |
| BufferSize | The size in bytes of Buffer. The number of bytes to read from the device. |
| Buffer | A pointer to the destination buffer for the data. The caller is responsible either having implicit or explicit ownership of the buffer. |
| EFI_SUCCESS | If Event is NULL (blocking I/O): The data was read correctly from the device. If Event is not NULL (asynchronous I/O): The request was successfully queued for processing. Event will be signaled upon completion. |
| EFI_DEVICE_ERROR | The device reported an error while performing the write. |
| EFI_NO_MEDIA | There is no medium in the device. |
| EFI_MEDIA_CHNAGED | The MediaId is not for the current medium. |
| EFI_INVALID_PARAMETER | The read request contains device addresses that are not valid for the device. |
| EFI_OUT_OF_RESOURCES | The request could not be completed due to a lack of resources. |
| typedef EFI_STATUS(EFIAPI * EFI_DISK_WRITE_EX) (IN EFI_DISK_IO2_PROTOCOL *This, IN UINT32 MediaId, IN UINT64 Offset, IN OUT EFI_DISK_IO2_TOKEN *Token, IN UINTN BufferSize, IN VOID *Buffer) |
Writes a specified number of bytes to a device.
| This | Indicates a pointer to the calling context. |
| MediaId | ID of the medium to be written. |
| Offset | The starting byte offset on the logical block I/O device to write to. |
| Token | A pointer to the token associated with the transaction. If this field is NULL, synchronous/blocking IO is performed. |
| BufferSize | The size in bytes of Buffer. The number of bytes to write to the device. |
| Buffer | A pointer to the buffer containing the data to be written. |
| EFI_SUCCESS | If Event is NULL (blocking I/O): The data was written correctly to the device. If Event is not NULL (asynchronous I/O): The request was successfully queued for processing. Event will be signaled upon completion. |
| EFI_WRITE_PROTECTED | The device cannot be written to. |
| EFI_DEVICE_ERROR | The device reported an error while performing the write operation. |
| EFI_NO_MEDIA | There is no medium in the device. |
| EFI_MEDIA_CHNAGED | The MediaId is not for the current medium. |
| EFI_INVALID_PARAMETER | The write request contains device addresses that are not valid for the device. |
| EFI_OUT_OF_RESOURCES | The request could not be completed due to a lack of resources. |
