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.

When I used Rinkya, and granted this was a few years ago, they were indeed the importer of record because they were the purchaser of record. Stuff arrived and went to them, and tariffs/duties on anything over the de minimis exemption had to be paid to them (I had to do this once or twice). They...

Unfortunately, not quite that simple. The problem with the 1.1.20.1 ROM is that it does not support the internal SCSI nor the internal video for MacOS (they work in AIX), and it does not properly enable the onboard MACE Ethernet. Also, Mac OS will treat it as a generic PowerSurge system and...

Where did you find a replacement?

Doesn't it transfer through the US, though? I thought their warehouse was States-side.

Status update on the 1.1.20.1 extension pack. Besides the already working ndrv for the video (the SCSI controller will be extracted the same way), I now have a working hack of Boot Variables that fixes the console between reboots. This goes in Startup Items and undoes whatever is messing with...

I just don't import anything anymore unless they explicitly ship direct and say they cover the tariffs.

Excellent!

How do you mean? I'm just going to buy the 64C Ultimate - I'm not recasing the 64U I already have.
