  21. Before trying to rely upon CPUID, a program must properly detect and sometimes
    22. 

  22. enable the instruction. In particular, the program must detect the presence of
    23. 

  23. a 32-bit x86 processor, which supports the EFLAGS register. Next -- if it is a
    24. 

  24. Cyrix or a NexGen processor -- the CPUID instruction may have to be enabled. Then
    25. 

  25. the program must try to toggle the ID bit in the EFLAGS register, to determine
    26. 

  26. whether the instruction is supported or not. Note that the program may face one
    27. 

  27. of the early Intel P5 processors: they do neither return a vendor ID string
    28. 

  28. nor the maximum supported standard level (when level 0000_0000h is queried).
    29. 

  29. Finally, notice that some chips support a partially programmable CPUID
    30. 

  30. instruction -- thanks to those idiot programmers who hard-coded "GenuineIntel"
