Sorry, that's 'hint.ahci_disabled', not 'boot.hint.ahci_disabled'.

On my system with ICH7 I have to use this, otherwise my SATA ports won't show up - AHCI tries probing and fails (some memory range reservation error), but NATA never takes over. We certainly should avoid these situations. Is there a way to pass attachment to NATA if AHCI can't figure it out?


Relevant pciconf output:

NATA doesn't attach as AHCI because this chipset doesn't support AHCI (and NATA can somehow check for that).
