The device handle and ROM image base can be used by consumers to determine which option ROM failed. Due to the black-box nature of legacy option ROMs, the amount of information that can be obtained may be limited.
The data header identifying the data. DataHeader.HeaderSize should be sizeof (EFI_STATUS_CODE_DATA), DataHeader.Size should be sizeof (EFI_LEGACY_OPROM_EXTENDED_DATA) - HeaderSize, and DataHeader.Type should be EFI_STATUS_CODE_SPECIFIC_DATA_GUID.
The handle corresponding to the device that this legacy option ROM is being invoked.
The base address of the shadowed legacy ROM image. May or may not point to the shadow RAM area.
