Ok, I'm glad the .txt extension issue got sorted out, let's see what's up with other ones.
bamacken, please just try re-downloading the image, it looks like your one is corrupted. I'll post md5 sums for all the image & firmware files in a short while.
@Fish, the bzImage and other files you see in the "spi" directory along with the Flash090.cap and CapsuleApp.efi ones are intended for those who want to build the firmware (cap or bin file) themselves. If you've already upgraded successfully using Flash090.cap - you won't really need these.
EDIT: And one more thing, a question. Fish, with this said
I'm going to have to wait for Intel to release the formal build for those of us whome can't build the image from scratch.
Looks like AlexT script would have setup the missing Linux build procedure steps, but I am not sure how to run it and it will definitely require additional information or instructions that I don't have.
what's your end goal? I could probably help you with an advice if I knew what you're trying to achieve.
