| 16 | Abstract:\r |
| 17 | \r |
| 18 | Load File protocol as defined in the EFI 1.0 specification.\r |
| 19 | \r |
| 20 | Load file protocol exists to supports the addition of new boot devices, \r |
| 21 | and to support booting from devices that do not map well to file system. \r |
| 22 | Network boot is done via a LoadFile protocol.\r |
| 23 | \r |
| 24 | EFI 1.0 can boot from any device that produces a LoadFile protocol.\r |

| 49 | Routine Description:\r |
| 50 | Causes the driver to load a specified file.\r |
| 51 | \r |
| 52 | Arguments:\r |
| 53 | This - Protocol instance pointer.\r |
| 54 | FilePath - The device specific path of the file to load.\r |
| 55 | BootPolicy - If TRUE, indicates that the request originates from the \r |
| 56 | boot manager is attempting to load FilePath as a boot\r |
| 57 | selection. If FALSE, then FilePath must match as exact file\r |
| 58 | to be loaded.\r |
| 59 | BufferSize - On input the size of Buffer in bytes. On output with a return\r |
| 60 | code of EFI_SUCCESS, the amount of data transferred to \r |
| 61 | Buffer. On output with a return code of EFI_BUFFER_TOO_SMALL,\r |
| 62 | the size of Buffer required to retrieve the requested file.\r |
| 63 | Buffer - The memory buffer to transfer the file to. IF Buffer is NULL,\r |
| 64 | then no the size of the requested file is returned in \r |
| 65 | BufferSize.\r |
| 66 | \r |
| 67 | Returns:\r |
| 68 | EFI_SUCCESS - The file was loaded.\r |
| 69 | EFI_UNSUPPORTED - The device does not support the provided BootPolicy\r |
| 70 | EFI_INVALID_PARAMETER - FilePath is not a valid device path, or \r |
| 71 | BufferSize is NULL.\r |
| 72 | EFI_NO_MEDIA - No medium was present to load the file.\r |
| 73 | EFI_DEVICE_ERROR - The file was not loaded due to a device error.\r |
| 74 | EFI_NO_RESPONSE - The remote system did not respond.\r |
| 75 | EFI_NOT_FOUND - The file was not found\r |
| 76 | EFI_ABORTED - The file load process was manually cancelled.\r |
