+  The entry point of PE/COFF Image for a PEIM.

+  If _gPeimRevision is not zero and PeiServices->Hdr.Revision is less than _gPeimRevison, then ASSERT().
+
+  @param  FileHandle  Handle of the file being invoked. 
+  @param  PeiServices Describes the list of possible PEI Services.
+
+  @retval  EFI_SUCCESS   The PEIM executed normally.
+  @retval  !EFI_SUCCESS  The PEIM failed to execute normally.
