Id pd.cpp constructor, the Mtrr::init(); have to be commented out.
According to the Intel Architectures Software Developer’s Manual, not all CPUs may implement MTRR. (Chapter MTRR Feature Identification).
Looking at the Mtrr:init() code, there seem to be a feature check missing. If you adhere to the Intel manual documentation, you should be able to implement and test this check.
