| // Follow UEFI 2.4 spec: |
| // To prevent name collisions with possible future globally defined variables, |
| // other internal firmware data variables that are not defined here must be |
| // saved with a unique VendorGuid other than EFI_GLOBAL_VARIABLE or |
| // any other GUID defined by the UEFI Specification. Implementations must |
| // only permit the creation of variables with a UEFI Specification-defined |
| // VendorGuid when these variables are documented in the UEFI Specification. |
| // |
| // Note: except the globally defined variables defined below, the spec also defines |
| // L"Boot####" - A boot load option. |
| // L"Driver####" - A driver load option. |
| // L"SysPrep####" - A System Prep application load option. |
| // L"Key####" - Describes hot key relationship with a Boot#### load option. |
| // The attribute for them is NV+BS+RT, #### is a printed hex value, and no 0x or h |
| // is included in the hex value. They can not be expressed as a #define like other globally |
| // defined variables, it is because we can not list the Boot0000, Boot0001, etc one by one. |
