Just out of interest, how does a hardware bug in a CPU get fixed by a software BIOS update? Isn't the bug a physical misconnection in the circuits?

Microcode updates.

So the bug was in the firmware of the CPU, not the physical circuitry?

I've never heard of or done a CPU firmware update. Are they included with motherboard BIOS updates?

Yes, the manufacturer of the MB releases a BIOS update to correct the
issue. For this particular errata, Intel has given the MB manufacturers
the information needed to do this.
