Running Mac OS X on x86 PC!

[S.MULLA]

a new emulator called PearPC seems to be able to run OS X on x86 machines:

Release date should be this weekend, if I'm informed correctly (V 0.1.1).

I know that the installation without a booatble partition ist possible, but I do not think, that you can reboot OS X after Installation, becaue PPC does not 'see' the partition.

[Starman]

This is what I don't understand.

Disk Util should do everything necessary to get the hard drive to be bootable. There shouldn't be a NEED for Darwin. Think about it this way - if you popped a blank hard drive into your Mac, you'd use Disk Util in order to get it ready, right? So why do we need Darwin? We shouldn't.

That said, I'm going to download Darwin and create a new image and see what happens when I get home tonight.

I reinstalled OS X again last night, but the Finder is crashing at all... Is there anyone ho has solved this problem?

What OS are you installing? I have 10.2 installed and actually have not crashed at all. I even got Office X to install and run (pretty slow)

[ataxy]

for those having problem booting 10.3 after installation someone as found a solution here

[KlyX]

@jedavis: I installed 10.3... I have no 10.2 around here. So I have to try it with an 10.3.

I agree. As a few people have said before, in the config file, uncomment the line that says the hard drive image is "hd". I booted into OS 10.2's installer after doing so, used Disk Utility, and without rebooting continued on and it saw the hard drive and installed.

:D

[Starman]

I'm downloading Darwin at work. I have some Mac development to do today so I can leave it up and running to try all this out.

Dont waste your time with darwin.

[SintaX]

How well would OSX perform on a dual cpu machine such as Dual-Xeon or Dual-Opteron ? Or maybe even 4+ =]

I do find this very interesting too, quite a breakthrough I have to say.

[ataxy]

Dont waste your time with darwin.

if you want to install 10.3 you will need darwin to redo you partion setup ounce you are done installing or else you hd partition will appear as unbootable

[KlyX]

Right, that's what I'm saying the hole time... maybe this is not so for Jaguar, but for panther...

[HaraldBluetooth]

Anyone who has got the network working?

I have a motherboard with built in Ethernet (nforce2). What drivers should I use (I use Linux)?

[Starman]

Dont waste your time with darwin.

Well I already wasted time WITHOUT it and my drive won't boot.

well the people at the offical forum have found a way to get the macosx to boot if it has not booted after the install and yes it does require darwin to do what is required i

here it is

OK Its working now. Luckily you dont need to reinstall OSX from scratch. It worked for me, but Im not sure (but a little confident) that it will work in all the cases, so if you doubt please make a backup copy of your current hard disk image just in case.

This is the way I fixed it:

1.- Download darwin (yes, Im sorry)

2.- Start pearpc using the installed OSX hd image as master and darwin iso as slave.

3.- Once darwin has stated drop to a shell by typing "shell"

4.- Enter the "pdisk" commands

5.- As in the normal installation select type "e"

6.- Enter "/dev/disk0" as the name of the device.

7.- If you want to see how your partitions are mapped enter "p".

8.- Use r to swap partitions, you have to set the map partition as the first one (Im pretty sure that it already is the first one) and the OSX partition as the second one (it was placed third in my installation).

9.- Finally enter "w" in order to write the partition table.

10.- Now its fixed, and it will boot without problems. Just boot with the OSX disk 2 in you slave because the installation continues :)

Anyone who has got the network working?

I have a motherboard with built in Ethernet (nforce2). What drivers should I use (I use Linux)?

READ BEFORE POST!

http://pearpc.sourceforge.net/netsetup.html

something interesting in "Plans" section of the site

Altivec support (JITC-X86 via MMX and SSE?).

Improve JITC-X86 (add FPU support, independent tb/decrementer, etc). Exploit the i386 MMU.

i think that means right now it's emulating equivalent of 286sx, and if you remember DX systems were about 2x faster

[jedavis1]

you can also do the same thing by booting with this command but ounce you are done wipe it out

prom_env_machargs = "-s"

Where did you get the parameters that work here? Are they just standard unix/linux commands line switches?

TIA for the info.

What Custom Install things do I install? Only the Essential System Software?

[daheffer]

WooHoo! OK. Thanks for all the help with this. I have it installing now. I have followed the whole Dawrin mantra, but I did it a** backwards. I installed OS 10.3, used DiskUtil, and installed most of the way. Then I decided to restart the install proces because while I was sleeping, it gave that error about the graphics. So I setup the partition map with Darwin, but didnt install Darwin. Now I am in the process of reinstalling 10.3 without all those damned options. Off to work while this installs, hopefully I get a chance during lunch to pop my head in and check on it. Thank you everyone for the help! :D

[Elliott]

Wow, butchered installations, but at least you'll all have the ability to say you're running Panther on XP. :p

[okt00]

Anyone have a direct link to the Darwin file needed?

Thankyou! I have been looking for quite a while.
