Get it from the coreboot website + check signature.

I would set it to load your disk .cfg file otherwise you would have to
do so via configfile (ahci0,msdos1)/grub2/grub.cfg or what not when it
boots to the rescue shell.

Asus KGPE-D16 with latest coreboot errors with Unsupported Hardware on Qubes 4 install missing IOMMU?

[petecb]

Well the good news is that I have now got this board to work with Coreboot v4.6 with the CMOS options and SeaBIOS! :-)

The bad news is that this obviously means a bug has crept in on the way up to 4.8 that prevents this board from working properly whenever the CMOS options are enabled. :-(

Thanks to everyone who provided help and suggestions during this journey (especially Taiidan!), it is a relief to finally have my new system up and working.

Kind regards,

Pete
