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

Maybe try installing a SATA drive to test things?

Worse case maybe disabling the SATA controller would fix it? as you say
you don't need it.

I hope timothy pearson sees this and replies as he would know what to do
to fix it.
