OK, well scratch what I said last time. The machine did boot, but the reason Trident said it couldn't find a Deneb board was because I hadn't reseated it fully in the card slot after setting the "No ROM" jumper. I also realized that there were no green LED's on on the Deneb.
So I reseated the card fully and rebooted. Now the machine won't boot at all. The No Rom jumper is in place, the top two LED's on the Deneb are lit ("FPGA booted" and "Zorro II mode"), but absolutely nothing happens, no disk activity or anything. It won't even boot from DF0.
I did the L-R mouse button boot and ran the Expansion Board Diagnostic. This is what I got:
Board Number Manufacturer Product Status
1 514 81 Working
2 514 3 Working
3 4626 23 Working
4 3643 18 Working
4 3643 19 Working
5 513 1 Working
The Deneb is board no. 4, mfr. 3643. According to the Deneb manual, this should show up as Products 18 and 20. I'm seeing 18 and 19. Is this (part of) the problem?
The current configuration, looking from the front is
Slot Board
1 empty
2 A2088
3 Deneb
4 Xsurf
5 A2091
6 empty
CPU A2630 with DKB2632
If I pull the Deneb out, it boots normally. Any ideas? I'm starting to wish I had just left the fool thing alone. At least before I reflashed the ROM, it was working.
Update: After about a dozen reboot attempts, I got it to boot off the Emergency OS 3.9 floppy, with the jumper removed on the Deneb. But now when I click on Trident, I get an error "Failed to load version 3 of Poseidon.library". All I can do then is click "Cancel". What's that all about?
Update 2: OK, I figured out how to assign the libs: so Trident was happy. Now in Trident I click to the Controllers panel and see Unit = 0, Online = No, and Product = unknown until online. So I click on the "Online" button at the bottom of the window and I get an error:
"Failure poseidon.library Opening DEVS:USBHardware unit 0 failed deviceInit failed to open(-1)".
This message is repeated three times. Now what?
Update 3: Just for laughs, I tried running Luciferin again. This time I get a pop-up error
"Your Deneb card has the ROM-OFF jumper set and thus the Flashrom contents are currently "DEACTIVATED" until you remove the jumper. This is only an information."
But I removed the jumper one or two reboots ago! This is shall we say, slightly mystifying.
