They both need IOMMU disabled in the BIOS in order to boot. The Sabertooth will work with the nouveau driver but the proprietary NVidia driver won't work as the NVidia card is detected as a AMD Radeon. I learned later that the Sabertooth BIOS says Windows, other boards have Windows and Other OS's support. I took this up with the Asus Tech Support dummies but they seemed like dumb dummies rather than smart dummies (Tm Amdahl). The Gigabyte board works with both the nouveau and the proprietary NVidia driver. I suspect these quirks are due to incompatibilities in the BIOS for these new motherboards. Any comments or recommendations on Linux compatible motherboards with modern chipsets. Intel a better solution that AMD perhaps? Regards Sid. -- Sid Boyce ...
