Communicating

is
used
to
communicate
the
status
of
such
an
erratum
fix
so
that
BIOS
or
system
software
can
determine
the
necessity
of
applying
the
workaround
.
Under
these
circumstances
,
the
erratum
workaround
references
the
specified
bit
to
enable
software
to
test
for
the
presence
of
the
erratum
.
The
erratum
may
be
specific
to
some
steppings
of
the
processor
,
and
the
specified
bit
may
or
may
not
be
set
on
other
unaffected
revisions
within
the
same
family
.
Therefore
,
software
should
use
the
CPUID

extended
model
,
model
,
and
stepping
as
the
first
criteria
to
identify
the
applicability
of
an
erratum
.
Once
defined
,
the

of
the

will
persist
within
the
family
of

If
CPUID Fn0000_0001_EAX is 00600F12h (OR-B2), then D18F4x164 is 0000001h. If CPUID Fn0000_0001_EAX is 00600F20h
(
OR-C
0), then D18F4x164 is 0000003h.
