Get information on CPU

/ * * Get CPU information with assembly EAX = 0 calls CPUID EBX, EDX, ECX Return to CPU OEM information EAX = 0 calls CPUID EAX 8--11 indicates a few 86 3 -------- 386 4 -------- 486 5 -------- Pentium 6 -------- Pentium Pro Pentium II 2 -------- Dual Processors

Detection is a P6 purchase frame EAX = 1 cpuid if Al = 1, is Pentium Pro Pentium II
