Presumably this means everyone else's 100-series boards will do the same.
As was expected.
Yeah, I debated whether it was worth posting (especially since the topic line alone pretty much says everything in the article,) but decided the question comes up enough in Kaby Lake threads that it was worth having an official "yes" to point to.
Do I get this right?
If you buy an "old" motherboard with the new Kaby Lake CPU, you'll need a BIOS update. But you won't be able to update the BIOS without a working CPU. So this will make you effectively need to buy a Skylake CPU first to get the desired BIOS version on the motherboard?!
Unless some (newer revision) motherboards come with the new BIOS that supports Kaby Lake out of the box.
That's what happened last time around, some mobos allow you to update with a USB stick others will be updated from the manufacturer.
This is exactly what I expected, but for all Kaby Lake (LGA1151) motherboards, not just MSI motherboards. It was predicted quite a while ago that LGA1151 motherboards with Intel 100 series chipsets will likely be compatible with Kaby Lake after a BIOS update, even though Intel is expected to release new 200 series chipsets (like the new Z270 chipset) alongside their Kaby Lake release.
