This has nothing to do with the legacy bios standards. The cpu starts
executing at 0xffff0 after reset, no matter what the firmware is. It's
the same for uefi and coreboot.
But, yes, mentioning the reset vector is reasonable, it you don't know
that x86 detail it isn't obvious indeed. Sending v2 in a moment.
cheers,
