Y'all might think about hosting a forum where it's much easier to find threads pertaining to problems. The mailing list archives are semi-searchable, but looking through reams of threads is a bit more challenging than looking through forums posts where you can quickly scan through threads.

Sorry to hear you're somehow stuck with a non-booting system.

The goal is to find the UFS /boot partition where loader.conf is located.
>From what I've read you have a legacy bios system, so probably no EFI partition, that means the partition you're looking for is probably da0s0a (if my guess was wrong, you can give da0s1a a try).
You can mount that one with "mount /dev/da0s0a /mnt" for example and edit the loader.conf that's in there.

You can also join us on #dragonflybsd on EFnet, that could be easier to help you.
Hope you can end up with a booting system again.
