Yonghong:
Below logic is incorrect. Index is the byte offset, not date type offset. So,
you should set Index = sizeof (EFI_FIRMWARE_VOLUME_EXT_HEADER) as the first
value, and use the below statement to access it.
(((EFI_FIRMWARE_VOLUME_EXT_ENTRY *)(ExtHeader + Index)) ==>
(((EFI_FIRMWARE_VOLUME_EXT_ENTRY *)((UIN8 *) ExtHeader + Index))
Thanks
