Thanks for that tip...I figured the checksum error was referring to something in grub's directory - not the ZFS checksums. Luckily, I have a spare 15G partition on my main drive. I installed into that, and I can boot just fine. It looks like my spare drive was the culprit.
Now I can move on to learning my way around OpenSolaris. ;) Thanks for the help! - Richard -- This message posted from opensolaris.org
