At least Windows 10 supports the Legacy BIOS, and most likely 12 will too. As long as they are making a 32-bit version of Windows they're still caring about the "legacy" PCs and we shouldn't be worried. Also, it's hard to imagine a coreboot'er who would be running 12 natively - not inside some virtual machine.

Hello! (Incidentally all of you are getting this because Google Mail delights in sending things out as reply-all.) I'm currently an observer in this set of circumstances but as it happens Stefan you are very right. My older laptop used a BIOS that was more suited to an earlier and even uglier release of Windows(!) and this one is using EFI and behaves strangely sometimes.
Oh and I was able to run Windows 8 and Windows 8.1 for a while on the older one. Slowly of course but those versions ran.
Let's see what does work..

if you boot windows 12 would you need tianocore?
Need is a harsh word, but the simple answer to a simple question is yes, you do.
You can use SeaBIOS, but Windows does not officially support legacy BIOS since at least Windows 7, so whatever works today might stop working tomorrow.

Yes, I would think so. But in case we are still on topic: It won't help you to boot Windows (unless you also implement UEFI services in your LinuxBoot and use a UEFI GRUB).
To chainload something for Windows I would currently go either one of these ways:
coreboot -> LinuxBoot -> SeaBIOS -> Windows loader coreboot -> LinuxBoot -> tianocore -> Windows loaderI think SeaBIOS already has an option to build a multiboot image. In either case you could also (in theory) pack either into a bzImage and feed that to kexec.
