Ouch. If they're not true Ultra-2 boards, it's unclear whether that
patch is appropriate. The README file says it's for Ultra 2 only.

A true Ultra-2 would have required that you shift jumper J2003 in order
to update the firmware. Otherwise it's write-protected. Because of the
position of that jumper, it's often necessary to remove peripheral
boards first to gain access; I assumed you had done so, which accounts
for the question I asked.
