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.
