The intel powered board was bricked by my turning off the TCP chip in the bios. So I am back to screwing with the pi's, plural as I bought spares. I had a spare that would boot hanging out in the air, and put a fresh install of an image dated Apeil 10th. Booted right up as soon as I fixed the video and networking stuffs. So I fired up synaptic, and had it update everything but the kernel. Died on wolfram engine, server disappeared. I took that out of the list and it completed the rest of the update AND REBOOTED JUST FINE. Shut down, moved the sd card to the pi I'd been fighting with, no boot. Swapped out the pi for another, booted right up. So that one I took out is marked with an MM. Now I need to recover my lcnc configs I saved off a card that wouldn't boot. But first, some din-din, its past time I fed the missus, me too since all I've had is coffee so far. Progress, I think. With a different pi, I'll re-test the OSHPark based interconnect cables before too long. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
