Subject: OS X on older Macs (instructions) Date: Saturday, April 7, 2001 7:36 AM From: Gary Hi tom; A very interesting read. http://homepage.mac.com/RyanRempel/OldWorld/Instructions.html Regards. Gary ----------------------------------------------------------------------------- Subject: More info on OS X for 6400 type machines Date: Monday, April 9, 2001 10:18 PM From: steve Tom, I thought you'd find this interesting. It's part of a discussion by people who want to get Darwin support working on the Alchemy-type machines. I don't have my 6360 anymore so can't mess around with it, but someone may want to give it a shot. The Alchemy file I sent is a set of OF patches pulled off an OS X disk, further back in the discussion I think Josh said it bombs out in the window manager when booting. You might also have to use Ryan Rempel's patched kernel (for 7300-9600 Macs). Have fun :).

That's what the OpenFirmware patch looks like. Apparently the same thing is in the newer Startup Disk program (a.k.a. control panel). You may have to hack that to recognize the 6400 series machines and apply the included patch though. I'm not sure how that works exactly. The guy (James) he's talking to (in the message below) would probably have more info on that. This would probably only work on Darwin at the moment, though it may also work with OS X. Once the OF gets stuff started anyway there's some hope the rest of it can be worked out. > Message: 15 > Date: Mon, 9 Apr 2001 14:06:46 -0400 (EDT) > From: James > To: Josh > cc: > Subject: Re: darwin and old(old)world Mac > > On Mon, 9 Apr 2001, Josh de Cesare wrote: > >> The patches have been released but they are probably not >> ready for prime time.

If you personally are interested in it you should check out the darwin-development list archives from Apple's site. There's an ongoing discussion about getting Darwin (or X) to boot on OldWorld machines. If you aren't, then you might want to post a link to the list archives and let one of your readers follow it up. As I said, I no longer have one of those machines to try it out on or I'd see what could be done. It doesn't sound horribly complicated, at least for Darwin. What there isn't is a one-shot tool to do what would need to be done, maybe once one of the guys working on it there figure it out they'll share the love with the rest of the world. FWIW the machines being discussed are a 5400, C500 and a 6400 (maybe one of the PowerComputing clones too). The engineer at Apple who worked on the patches didn't have time to finish them but says they mostly work. You can probably ditch the patch I sent you though, if you have OS X then you have a copy of it.
