Hi Ryan,

	Thanks, but I'm not sure if FreeBSD even booted. I had 
EXPECTED it was a case of it just sitting at a prompt waiting for
an FSCK, but when I cabled to the serial port, I couldn't get it to do
anything. I also don't see any post crash evidence that it attempted
to boot. So oddly it was in some state where it wasn't under its BIOS
control, and it wasn't under FreeBSD control. I didn't know if there was
some magic key sequence (ALT, SHIFT, HOP ON LEFT FOOT, D) that might have
told it to tell me what it was doing at the current moment. Unfortuantely
I had to reboot so if there was its lost now. :-/ A quick google
turns up http://www.webweaving.org/watchdog/ to answer your query
about a FBSD/Soekris watchdog. I'm installing it now.

		Thanks, Tuc
