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:

Great! Finally got it to work! I must say I'm quite impressed by how fast it works. Of course it is nowhere the speed of a real Mac but knowing how difficult PPC emulation is I expected it to perform a lot worse. Can't wait for the next version :)

Here's a screenshot:

hehe, monkey island!

Howd you get american flag there :o

i tried the kevin rose config file and it gives me the same message:

D:\pearpc>ppccfg.osx (this is what i put in)

'ppccfg.osx' is not recognized as an internal or external command, operable program or batch file

and then when i type...

D:\pearpc>ppc ppccfg.osx

ppccfg.osx: I/O error: No such file or directory

usage: ppc configfile

why am i the only one having this problem???

Hmm.. anyone have a link to a 6GB hard drive image? I have tried the one on the offical site, but everytime I try to use it, it gives me a: "[iO/IDE] <Error> invalid format <filesize isn't a multiple of 516096>"

[evacsoul]

You left out the extension after pci_ide0_slave_image = "Mac OSX 10.3 CD 1" ... it should point to the .iso file

you also need to comment out the networking stuff- change it to

#pci_3c90x_installed = 0

#pci_3c90x_mac = "de:ad:ca:fe:12:34"

try that

Well, it works. OS X Running Windows Running OS X :p

[Kayle12]

Hi,

Do you think it will run OKAY on my computer. (Mac OS 10.3 Panther)

I have a copy of it and I want to try it.

AMD XP 2400+ (2.00GHz)

512 Ram

40GB HD

What do you think?

Is it very hard to get to work?

Thanks

Kayle

[ProtoPunch]

this itself has renewed my interest in getting a mac.

I think everyone here would wish OSX ran on pc :p

this owns so bad, I feel like running down to the local compusa and getting a copy of panther (I won't :p)

[Keitero-sama]

Glad I own an old beige G3. (Slow 300MHz w/ 96MB of ram and OS X 10.1)

[Redestium]

Well, it works. OS X Running Windows Running OS X :p

Nuts nuts... :blink: :blink: :p

[jedavis1]

thanks for yourr help jon, but everytime i attempt to run the config file from the run dialog, it gives me this message:

D:\pearpc>ppc ppc configfile (this is what i type in)

usage: ppc configfile (this is what it tells me)

and when i type in:

D:\pearpc>ppc ppc_configfile

ppc_configfile: I/O error: No such file or directory (this is what it tell me if i type in anything except the first example)

i'm not really sure why i won't run the file, the name of my configfile is "' ppc_configfile'' (with the space mark in the file name) . it's in the pearpc folder along with a .bat file with the same name. any ideas? :wacko:

You did it correctly when you typed: "ppc ppc_configfile"

The problem is that you in your sample:

D:\pearpc>ppc ppc_configfile

You are on the D: drive but in the sample of the ppc_configfile you posted earlier, you have this line:

#Master Device

pci_ide0_master_installed=1

pci_ide0_master_image="C:\pearpc\macosx_6gb_unjournaled.img"

pci_ide0_master_type="hd"

You have your image listed as in the pearpc folder on the C: drive. You need to make sure that they all point to the correct drive and location:

[phalanx126]

sorry about the confusion, but i changed it to D in my new config as well. i tried evacsoul's suggestion and i managed to get the PPC screen, but then i get this message:

[CPU/MMU] new pagetable: sdr1 = 0x00300003

[CPU/MMU] new pagetable: sdr1 accepted

[CPU/MMU] number of pages: 2^15 pagetable_start: 0x00300000 size: 2^18

[iO/PROM] <Error> Can't open boot file

right before i get the last line with the error, PPC shows only one bootable partition, labeled:

"1. partition 2 of 'disk0' (Apple_HFS_Untitled_2/Apple_HFS)

i pick this as my choice and then i get the error...

[unrealism]

Did I hear the words Speed Boost?? How... How... :D :D

[okt00]

@Kayle12 I am running an AMD 1800+ with 512mb of ram and it works fine, nice and fast too! well quick enough for me!

[Emon]

Well, it works. OS X Running Windows Running OS X :p

dude .. I tried that way before u did .. :p

Hmm.. anyone have a link to a 6GB hard drive image? I have tried the one on the offical site, but everytime I try to use it, it gives me a: "[iO/IDE] <Error> invalid format <filesize isn't a multiple of 516096>"

I got that error for a while. What is the exact filesize of your disk image when you get that error?

When I recieved that error, I found that my 6gb images were only extracting to ~4 gigabytes (hence, the faulty disk geometry). I checked the disk the PearPC was on and found out to be a Fat32 drive.

A Fat32 drive will only support filesizes up to ~4gb in size, hence the whole disk image could not be extracted and used.

I converted my drive to NTFS and it created the whole 6gb drive file that worked perfectly.

@Kayle12 I am running an AMD 1800+ with 512mb of ram and it works fine, nice and fast too! well quick enough for me!

Yeah, ram is my achille's heel when it comes to speed I can do something about.

My whole system only has 256mb which is fine for Windows XP, but a Mac sitting on top of it really sucks down the MB.

;)

[nmbr6]

Okay I tryed the premade 3gb image and it did not work. It installed completly but it said I didnt have any bootable partitions. So back to the start.

I am now using the 6gb image and using darwin.

Is it supposed to sit at "The following Devices are available for installation" without showing anything or am I running into more problems?

If so how long have you guys been waiting?

@Kayle12... I'm running an OCed 600 MHz Celeron (to about 750 MHZ) with 384 MB ram and it runs decently for me. I mean, I really can't complain. Performance right now primarily deals with the architecture of the program itself, and it's lack of support for many of the instructions (altivec etc.) inherent to a PPC processor. Albeit you probably shouldn't try to run it on a crappy system (OK so I'm a hypocrit ;) ). Your system is not crappy! Give it a few months, a few years even perhaps, and performance will increase. I wish I could hop onto the dev. team myself... Anyway, you should be fine with your config. ESPECIALLY if you open up the Task Manager and give it a higher processor priority, and increase the ram size in the config file. While this kills other system performance... it makes OSX go visibly faster. GL with the install.

[Redestium]

With the amount of excitement that is pushing this and the fact that anyone can jump on board and help development I think this is going to be one wild ride. :)

[colordeficiency]

:yes: I'd love to see where this goes and what will IBM or Motorola do bout it.

Use teh nightly optimized builds. much better.
