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.

It's been a long day, I should have thought of that. 0 > list-partitions scsi/sd@2,0 # Start Size Name Type CPU Sigs 0 1 2 Volume 01 00000001 0000003F Apple Apple_partition_map...

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...

So are you saying that adding 0 to my-self before opening the device should be enough?

A reminder that ANS Open Firmware seems to take the input device and output device literally. If they are set to the serial port, video is never initialized. If they really want this, the solution is just not to run the NVRAM fixer. This is in Startup Items - it's a regular application, so it...

Welcome.
