Ack, my apologies. Forgot about that. Yeah, you will need to do it from the loader prompt if you want to test it. Unless you are booting off of gmirror or have /etc/fstab configured with something else that will automatically be found, you will have a problem. But from the loader prompt it should be... load /boot/kernel/ahci.kp show rootdev If rootdev shows any thing other than shows boot device as ad, rewrite it as ada, using the set command. See loader(8). This will get it to boot, although it will error and drop to single user mode as /etc/fstab contains the old stuff. Just manually mount everything and continue. At this point it should be up and running and able to test it out.
