- Backup original dsdt to /dsdt/originaldsdt in the IORegistery
- Added kernel patcher, removes the CPUID check panic in the kernel. Forces _cpuid_set_info to
return Penryn / cpuid model 23
- Implemented SPD memory automatic detection and injection,seems to work really great ...
- Factorized code to prepare a dynamic memory detection algorithm ...
- Optimized smbios table address search
