Re: [Bug 3187] FaultTolerantWriteDxe defect will cause NVRAM not recovered after number of WorkSpaceRefresh().

HI Gaoliming,

The DupCodeChange is for simulating user force power off the system.
So I just use the CMOS to record the temporarily flag to ensure the code will not enter the infinite loop to reset the system.

Best Regards,
Marlboro.
