[coreboot] Removing Absolute BIOS (a commercial backdoor) from a Home Computer

Hello,

I would like to run coreboot on my home computer to disable Absolute BIOS. I
didn't want it but had little choice when I got my new Lenovo PC.

I see the download page on your site, but I am not really sure how to make
coreboot work on my computer as the download doesn't appear to have an
executable, but various components that are implemented according to specific
steps which I don't want to screw up and brick my new computer. XD

Please advise and thank you in advance!

Best,

Keith Krohn
