- // =======================
- // Author: Benjamin Jurke
- // File history: 27.02.2002 - File created. Support for Intel and AMD processors
- // 05.03.2002 - Fixed the CPUID bug: On Pre-Pentium CPUs the CPUID
- // command is not available
- // - The CProcessor::WriteInfoTextFile function do not
- // longer use Win32 file functions (-> os independend)
- // - Optional include of the windows.h header which is
- // still need for CProcessor::GetCPUFrequency.
- // 06.03.2002 - My birthday (18th :-))
- // - Replaced the 'rn' line endings in function
- // CProcessor::CPUInfoToText by 'n'
- // - Replaced unsigned __int64 by signed __int64 for
- // solving some compiler conversion problems
- // - Fixed a bug at family=6, model=6 (Celeron -> P2)
