I honestly can't remember where I pulled this document from, so I cannot give credit to the source. I think I may have edited it anyway. But this has been really helpful for me.
Also PRAM Doctor really is a great tool. Not only can you view ALL PRAM/xPRAM settings, but you can also directly edit them in there. So in this case, get your PRAM setup like you want, then go into PRAM Doctor and capture the settings. |

Where can I find a copy of that? |

PRAM Doctor is part of this combined download. You can mount this in an emulator like Basilisk then scrape out the program from there. There are three pages, and on each page you can hold down Command-Option to modify the values. Then you can "write" the value back to PRAM.

What I also found out: "Pram Doctor" is not suitable. Maybe it's way too old. Sometimes the saved PRAM data contains strings from system menus or even displayed text. So I ditched that app for comparison etc. I have run into this issue with PRAM Doctor as well. Trying to remember the details, but it might have been on a PowerBook 540c perhaps? But generally for my other 030s and 040s it has worked pretty well. |
