After reading all that GREEK, which gave me a headache,
It looked to me like the OS is lost, confused, FUBAR, or just having a real bad day, which in turn makes me think Hard Disk, somewhere in the initial 10GB of a drive.
David, it could be a BIOS setting, but I think it's improbable (low odds). When that happens with these, they like to not boot at all until you go in and fix 'em.
I would look to see if you have a failing/failed drive somewhere in that mess and hope your OS is not hosed.
-AND-
David, wasn't the old v2 OS prone to confusing itself by not deleting things it should? I can't remember, but that is your department (punt).
