  AFAIK there is just no official statement of Intel about Pentium
III, IV and M CPUs. That may also be because they want(ed) people
to buy newer machines. Nonetheless I would be in wonder if
nobody at all had ever tested these CPUs for Spectre and
Meltdown. The issue itself wasn´t discovered by Intel either.
