    Hmm, good question.  I'd always thought that the text string was 
    actually loaded into the CPU by BIOS, but I just checked the spec, and 
    that doesn't seem to be true.  (Maybe it is true for AMD processors, I 
    really don't know anymore.)  Regardless, as I see it, we've always tried 
    to make our own determination.
 
 
 my reading of the intel or amd manual a month or so ago said that
 the bios is expected to load 48 chars for the cpuid string.  i don't
 recall which off hand, but i think intel.
 
 
 .mrg.
