I do not understand that paragraph. Could you please elaborate how you
figure out that the SATA controller is not running in AHCI mode anymore
after powering off.

In coreboot since some months AHCI mode is the default mode and
therefore everything should work out of the box. Even if you selected
NATIVE (IDE mode) only loading the payload like GRUB or SeaBIOS would
take a little longer. Afterward for example the Linux kernel switches to
AHCI mode anyway [1].

I do not even know if the vendor BIOS ships these ROMs. But
`bios_extract` would be the way to go to check.


Thanks,

Paul
