So there is a new driver - never heard about ahci ;) Is it sufficient to boot 8.0-RC1 livefs? It looks like ahci is not included in GENERIC so I have to load the module in the 2nd bootloader I guess. Something else like disabling the old ata driver? Or will the new driver be used automatically. I was not sure about the man page what "this one" means (the ataahci or the ahaci?): AHCI hardware is also supported by ataahci driver from ata(4) subsystem. If both drivers are loaded at the same time, this one will be given precedence as the more functional of the two.
