(Hi, Dan ... this probably needs to go over to questions@freebsd.org, where more experience folks will see it, so I'm redirecting the CC there...) Ouch! I hope your disk can recover. Once you get this grassfire out, be sure and check your backup strategies.... The *only* command you can enter isn't even really a command, it's simply the answer to the question "where the heck is /boot?" which is something the system desperately needs to know. IIRC (and who knows, it has been a little while since I saw this one, thank Deity) it gives you a hint or two about what to do. The usual boot device is /dev/ad0s1 (for IDE drives) or /dev/da0s1 (for SCSI) and the filesystem type is normally ufs (but that could vary, ufs2 for example). Once you get in, you will want to fsck and attempt to remount your slices; you probably won't have access to a lot of normal tools (for at least two reasons I can think of: one being that some of them are on the /usr partition, and the other being that $PATH is not set, so even stuff in /bin and /sbin will *say* "not found", just call 'em by the full path /sbin/fsck, /sbin/mount, etc.) If everything fscks clean, try rebooting again to return to multi-user (normal) mode. Good luck. Kevin Kinsey
