I put a note in the wiki (flashrom).

there was talk about the Gigabyte 570SLI board with pads for DUAL BIOS.
Would be interesting to know whether the secondary soldering pads are
functional or not.
If booting from PCI expansion ROM can be made possible, it may be quite
handy for some LinuxBIOS developers who like to fall back to
manufacturer std BIOS without much hassle (unplug the PCI card). --Q
