The SCSI ndrv Extension is configured exactly the same as the 54M30 one, with the right Type and a valid cfrg resource, yes. I'll look into the PCI DDK. Perhaps it will be simpler to just generate a driver based on that, and tweak it for the 1.1.20.1 ROM's PCI slot enumeration.

Game over, man!

Oh, I thought I had posted that here before. Here is what the relevant sections look like: /Devices/device-tree/bandit name bandit 62616E64 697400 ?ESB FFFFFFFF...

Well, actually, it looks like the SCSI ndrv is not working after all. I checked and the SCSI controller is indeed not showing up in TattleTech or Apple System Profiler. Notably, the Cirrus Logic video, which is also PCI connected but the ndrv does work, is not actually being treated as a PCI...

I appreciate your careful consideration. I am hopeful we can come to a better understanding of how the hardware functions. What @Mr. Macintosh did is notable in that we can see the steps the AI took to patch the binary, so we can reverse-engineer its conclusions (and streamline the process)...

What did you use for a HAL?

Interesting. The transcript is very helpful and it's impressive it got that far, even though it's (as expected for an AI thrashing around on the data set) a bit prolific. Thank you for posting it. I think the next step is to create a patched VENEER with what the AI did (and also to catalogue...

Apropos of nothing, but nice Octane. :)

Ethernet extension is done except for making a nice icon. We no longer need the nvramrc, though @joevt's 0 to my-self did get it working. Last stop is to extract the SCSI driver and then polish up everything.

That is very promising, but we really need a full transcript of what you're doing, or it will be tricky to replicate.

I'm not sure what the wiring is (I can buzz it out if you really want), but it's just an off-the-shelf Mac serial MiniDIN-8 to DE-9 null modem. There are tons of sellers on eBay.

That indeed looks like a full register dump, but what command did you use to generate it? Do you have the full transcript of what you did? I want to make sure we're capturing the right information. I use a PL-2303 USB-to-serial dongle (an old iConcepts PDA adapter; it works with pretty much...

Yes, I'm booting it from external SCSI, but I'm out of town for a couple days - I will check for you when I get back.

No, we have this part. We need the full register dump. Thank you for trying it, though - proves it's not just my hardware, but what ROM did you do this with?

No, actually, now that you've explained it, it sounds like you're zapping PRAM on each reboot, and that would also work because it sets the device settings back to the defaults. But it's obviously inelegant, ergo the NVRAM fixer. I'd be interested to see what Apple System Profiler comes up...

7.5.3 is ... a choice :) I suppose you could get 7.5.2 on there, though nothing earlier than that, of course. But I ran into fewer problems with 8.x and 9.1. I'm not sure I understand the question. The problem seems to be that Mac OS sets the Open Firmware input and output devices to the...

OK. Might do a belt and suspenders approach if that works (nvramrc *and* INIT, so that way one or the other will set the property). I have no idea where the ttya setter is, only that it's not Startup Disk (for that matter, the string doesn't even appear anywhere in either fork). I'm also not...

Yes, if you reset the PRAM, it will come up (though your settings will be whacked, of course). You can also change it from the serial port and restart. In my case, before I wrote up the NVRAM fixer, I just keep the PRAM battery out entirely. If the system gets wacky, I shutdown as cleanly as I...
