I was reading that in order for kaby lake to be supported on 100 series chipsets, a BIOS update is required.

Wikichip also displays that Sunrise Point is still supported but with a BIOS update : https://en.wikichip.org/wiki/intel/microarchitectures/kaby_lake

What specifically would this BIOS update do to allow for a kaby lake CPU to be supported. Or indeed in the general case, what would a BIOS update do specifically to make a chipset compatible with the CPU.

I have heard BIOS updates update microcode in the MSROM but that's probably not the only thing. There are many tutorials on google about how to update the BIOS but not many about what it actually does.

  • Maybe something about how it sets up the onboard GPU (which did change from SKL), or maybe things about configuring power-management. – Peter Cordes Jan 27 '19 at 21:53
  • I have a new suggestion. Perhaps the device and function numbers of the components on die have changed on kaby Lake and the bios needs to alter its way of configuring – Lewis Kelsey Mar 13 '19 at 06:40
