LegacyBbs.c When CSM uses EFI_SEGMENT and EFI_OFFSET to call CSM16 function, some CSM16 use es:[offset + 0xabcd] to get data passed from CSM32, offset + 0xabcd could exceed 0xFFFF which is invalid in real mode. So added NORMALIZE_EFI_SEGMENT and NORMALIZE_EFI_OFFSET to keep offset as small as possible to avoid this issue during CSM16 function call. 2012-03-01 11:16:42 +00:00
