Please do not ever change more than a single thing at a time. You
waste not only your own time, but also that of those who help you.

Try changing only the SATA setting before moving on to anything else.

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

Hi Peter,

Thanks for your message.

I certainly did not mean to waste anyone's time.

The SATA setting that I was initially looking to enable was already set this way in the default file. Presumably it's only disabled if you don't enable CMOS settings in the nconfig. As I never came across any documentation that discussed enabling CMOS settings for this board, I had previously not enabled them. Therefore I think there is much that could be improved in the documentation to help people new to coreboot trying to set this board up. I am hopeful that I may be able to put some time to helping with this in the coming months, as a thank you for all the help I have received so far.

As the default SATA setting already appeared correct, I modified the 3 additional settings that Taiidan had already indicated worked (memory_speed_boost, 1394 controller and SATA ALPM) so in my mind I was only adjusting one additional setting, the memory voltage. I thought this was fairly sensible as my RAM is definitely 1.35V.

I would value confirmation that it is safe to run the Crucial CT16G3ERSLD4160B RAM I have in this board at 1.5v.

Kind regards,

Pete
