| 23 | // To prevent name collisions with possible future globally defined variables, |
| 24 | // other internal firmware data variables that are not defined here must be |
| 25 | // saved with a unique VendorGuid other than EFI_GLOBAL_VARIABLE or |
| 26 | // any other GUID defined by the UEFI Specification. Implementations must |
| 27 | // only permit the creation of variables with a UEFI Specification-defined |
| 28 | // VendorGuid when these variables are documented in the UEFI Specification. |
| 29 | // |
| 30 | // Note: except the globally defined variables defined below, the spec also defines |
| 31 | // L"Boot####" - A boot load option. |
| 32 | // L"Driver####" - A driver load option. |
| 33 | // L"SysPrep####" - A System Prep application load option. |

| 37 | // defined variables, it is because we can not list the Boot0000, Boot0001, etc one by one. |
