Default How does the Skylake fix work?

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?

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?

Judi replies, "You are on the other side!"

Just add it to the long list of other things that you have never heard of,

Such as getting a job, meeting a woman.

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.

I've read in MB BIOS update instructions that it fixes X to do with the CPU, but I always assumed that was a motherboard fault where it didn't work with new types of CPU etc.
