Thanks for confirming the md5sum and the suggestion.  It also fails boot
to level 1.  I used rescue to turn on /etc/default/bootlogd but nothing
gets logged to /var/log so I guess it doesn't get that far.  I would
have liked to know where it fails, since it does boot rescue CDs.  I am
giving up assuming it is the motherboard.
