Ahhrgh! Well, thanks for letting me know. I knew about the power
sequencing chain and the cables and stuff, but where the heck should
one get those jumpers from? I was hoping there was some jumper of
dip-switch on the inside that would let me override this. May be
I should cut one of the cable that I do have and just cut the two
wires short? Would that make a functional jumper? Or has anyone
gotten a box of those and could give me one?
