Hi,
I have an Asus KGPE-D16 motherboard I am trying to get working with Coreboot
and use with Qubes 4. It has a single AMD 6386 CPU and 128Gb DDR3 ECC RAM.
I have successfully cloned the git repository and built the coreboot.rom.
However when I flash it on to the board and then run the Qubes installer it
complains that there is an “Unsupported Hardware Error” and I get the text
"This hardware lack features requred by Qubes OS. Missing features:
IOMMU/VT-d/AMD-Vi , Interrupt Remapping”
If I install Fedora and run dmesg, AMD-Vi and the IOMMU all appear to be fine.
I have tried flashing the board with an older version of Libreboot and can
confim this proceeds through the Qubes 4 installation without issue. However, I
wish to use a recent version of Coreboot for support of a Pci-E SSD and to
ensure I am running the latest microcode updates.
Can anyone offer me some guidance please?
Is it possible I am not selecting the right options when I do “make nconfig”
before building the rom?
Kind regards,
Pete
