8.1i EDK - DCR routines DcrOut and _DcrIn read and write incorrect values from the registers


The DcrOut and _DcrIn DCR routines read and write incorrect values from the registers.


To work around this issue, change the optimization level for the drivers as follows: 


1. Inside of XPS, select Project from the pull-down menu. 

2. Select Software Platform Settings. 

3. Bring the middle tab forward. 

4. In the extra_compiler_flags entry, insert "-g -O0". 


A fix for this problem is included in EDK 8.1i service pack 1.
