So, let me just expose my ignorance here, does Coreboot provide an interface
like a traditional, proprietary BIOS which allows the user to configure
different settings?  Settings like boot order?  Because I guess I don't
understand the purpose behind the whole discussion.

I would have expected Coreboot to work it's way down a prioritized list
looking for boot media (MBR in x86).  Is it accurate to replace the words
"boot media" above with "payload"?  Is MBR code (be it FILO, GRUB, whatever
Windows' bootloader is called) a payload?



I wish I had a Kryptonite cross, because then you could keep both Dracula
AND Superman away.
