+MISC_SUBCLASS_TABLE_FUNCTION (
+  MiscSystemManufacturer
+  )
+/*++
+Description:
+
+  This function makes boot time changes to the contents of the
+  MiscSystemManufacturer (Type 13).
+
+Parameters:
+
+  RecordType
+    Type of record to be processed from the Data Table.
+    mMiscSubclassDataTable[].RecordType
+
+  RecordLen
+    Size of static RecordData from the Data Table.
+    mMiscSubclassDataTable[].RecordLen
+
+  RecordData
+    Pointer to copy of RecordData from the Data Table.  Changes made
+    to this copy will be written to the Data Hub but will not alter
+    the contents of the static Data Table.
+
+  LogRecordData
+    Set *LogRecordData to TRUE to log RecordData to Data Hub.
+    Set *LogRecordData to FALSE when there is no more data to log.
+
+Returns:
+
+  EFI_SUCCESS
+    All parameters were valid and *RecordData and *LogRecordData have
+    been set.
+
+  EFI_UNSUPPORTED
+    Unexpected RecordType value.
+
+  EFI_INVALID_PARAMETER
+    One of the following parameter conditions was true:
+      RecordLen was zero.
+      RecordData was NULL.
+      LogRecordData was NULL.

+{
+  STATIC BOOLEAN  Done = FALSE;
+
+  //
+  // First check for invalid parameters.
+  //
+  if (*RecordLen == 0 || RecordData == NULL || LogRecordData == NULL) {
+    return EFI_INVALID_PARAMETER;
+  }
+  //
+  // Then check for unsupported RecordType.
+  //
+  if (RecordType != EFI_MISC_SYSTEM_MANUFACTURER_RECORD_NUMBER) {
+    return EFI_UNSUPPORTED;
+  }

+  // Is this the first time through this function?

+    //
+    // Yes, this is the first time.  Inspect/Change the contents of the
+    // RecordData structure.
+    //
+    //
+    // Set system GUID.
+    //
+    // ((EFI_MISC_SYSTEM_MANUFACTURER_DATA *)RecordData)->SystemUuid = %%TBD
+    //
+    // Set power-on type.
+    //
+    // ((EFI_MISC_SYSTEM_MANUFACTURER_DATA *)RecordData)->SystemWakeupType = %%TBD
+    //
+    // Set Done flag to TRUE for next pass through this function.
+    // Set *LogRecordData to TRUE so data will get logged to Data Hub.
+    //
+    Done            = TRUE;
+    *LogRecordData  = TRUE;
+  } else {
+    //
+    // No, this is the second time.  Reset the state of the Done flag
+    // to FALSE and tell the data logger that there is no more data
+    // to be logged for this record type.  If any memory allocations
+    // were made by earlier passes, they must be released now.
+    //
+    Done            = FALSE;
+    *LogRecordData  = FALSE;
