Right. Upon powering on, to get the system to boot normally, I hit the F12 key which brings up a box that lets me choose either my hard disk or my optical drive to boot. When I do not hit F12, I get the LBA errors and the "ZFS: i/o error - all block copies unavailable" error shown in previous posts to this thread. If I boot into the non-F12 broken state and leave the system alone, it appears to try and boot twice and gets the same LBA errors and the same ZFS error. Again, if I install FreeBSD off an installation CD and use sysinstall to install a typical UFS-based system it boots without any trouble at all, F12 or not, leading me to believe that there's some sort of difference between the plain bootloader and the ZFS-enabled bootloader with respect to the way they interact with the BIOS. Another oddity I noticed is that if I change the SATA mode in the BIOS to "IDE Native" mode, the hard drive activity light stays on, even when the system is booted and is sitting idle. If I change it to "AHCI", I do not see this. I doubt this has any relation to ZFS, but it was just an interesting observation.
