| One other thing you could try is a cold start (CTRL+PAUSE+RESET). It will wipe all your 102’s memory, but maybe it will help?
Royce Sent from my iPhone I had checked the connectors and pins before I wrote, and I was even going to check for continuity on each pin but that's going to take a while and be error prone with 40 pins. The connector on the underside of the DVI has the snap-in latches which are engaging. I can't push any further and I haven't bent any pins. The cable is new from Gregory (Arcade Shopper), so I don't have a lot of reason to suspect it.
Besides trying two different 102s I've also tried batteries and wall power for the 102s, and I even upgraded one to max out the RAM just in case I was missing a memory requirement.
The DVI unit itself was pristine on the inside when I first looked at it. I'll have another peek inside to check the connector; perhaps it experienced some trauma and there are broken traces on it. But I really don't want to look for problems where they are unlikely or fix things that are not broken .. I've learned that every time I disturb something there is risk involved.
Is there anybody in the Seattle area (northern suburbs) with a known good cable? If I can eliminate the cable as a possibility then there is only the DVI connector, as the rest of it seems to function normally.

When I had this issue, it turns out I hadn’t snapped the connector in fully on the underside of my M100. I would disconnect it and ensure no pins became bent and flattened out. If the pins look good, carefully replace the connector and snap it firmly into place.
When making my cable, to figure out the location of pin 1 on the M100 and the DVI, I think I used a multimeter and the pin outs in the various manuals to look for ground pins which gave some insight into the orientation of the connectors.
Seeing “please wait” followed by a Microsoft copyright is a very good sign that your boot disk was successfully read.

That goes into the IDE ribbon cable, which is connected to the DVI also using the orientation in the pictures from the Wiki.
