F4x164 Fixed Errata Register
Communicating the status of an erratum requiring a workaround within a stepping of a processor
family is necessary in certain circumstances. F4x164 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 revisions of a processor, prior to the definition of a bit may
not be affected by the erratum. Therefore, software should use the stepping as the first criteria to
identify the applicability of an erratum. Once defined, the definition of the status bit will persist
within the family of processors.
