OS X on x86

Howto here

Copy of text:

This
is the most simple guide to installing Mac OS x86, it looks longer
because its very simple if you can browse the internet and check e-mail
you can do this! I made this guide so that more people are able to do
this without asking 100 questions during the process by following other
guides. This will work on ANY x86 cpu with SSE2 or SSE3 and heres a screenshot for some motivation :p

The Instructions in green are for Native installation on your computer and blue for VMWare installation.
So for native installation follow everything except blue and for VMware
follow everything except green, just to make things clear.

Warning:
If you choose to install it native on your computer, there are less
chances of it working since every computer is different and this OS is
intended for one specific OS so I recommend installing it on VMWare
first.

Before you begin:
– Make sure you have a SSE2 or SSE3 capable cpu, download this Tool to find out -=> CPU-Z
If you only have SSE2 and not SSE3 then only x86 binarys because for
ppc binarys you need Rosetta which requires SSE3. It is still worth
installing since everything included in the OS works except for iTunes.
– You need Windows XP and around 12gb of free space / A spare IDE hard disk with atleast 6gb space

– You will also need these things
1) VMWare 5
2) UltraISO (has to be full version and no older than 7.6)
3) Stuff.zip (contains patches)
4) PearPC
5) HD Image
6) Darwin8.01 (rename this to .iso instead of .iso.gz after downloading)

Instructions:
1) Unzip PPC folder from PPC.zip and edit ppc.cfg file in notepad and
edit the first few things like it says in there and unzip the HD Image,
it will unzip and become 3gb and put it in folder PPC, the one you just
extracted.
2) Get a hold of Mac OS Tiger x86 Developer Kit Install DVD I assume
you have the actual DVD (obtained legally) and a .dmg file for it and
this is why you will need to install UltraISO to convert it. After
installing go to Tools > Convert and select Standard ISO and convert
it. If ISO format does not work later on use .img format.
3) After configuring ppc.cfg and checking it again, right click on
ppc.exe and click “Create Shortcut” then right click in that shortcut
and in the Target box at the end type this after ppc.exe: ppc.cfg
then press OK and double click it to open. Select the CD Rom boot
option (probably 2) then go through setup and make sure you do not
select Developer tools, printer drivers and fonts so that you can fit
in the 3gb image. Finish the install after reboot, open shortcut to
ppc.exe again and finish the installation until you boot properly to
the desktop and then just shut it down.
4) Install VMWare 5 and
create a new (File > New > Virtual Machine) and select these
optoins ( Custom > New > Other for both > Select ram size you
want > Bridged Networking > Buslogic >New Virtual Disk > IDE > 4.0Gb and check Allocate Space Now and Finish Use
a physical hard disk > Select which Disk you want to use (if you
don’t know which is which, right click on My Computer, click Manage,
click Disk Management and check there) also make sure you use the
entire disk thats why it must be a spare HD > select filename>
Finish ). Now in the Devices section double click on CD-ROM (IDE
1:0) so you can edit it and check Use ISO Image and use the Darwin ISO
file (make sure you rename it to .iso) then press ok.
5) To
Install Darwin Press green Play icon on the top, after you see big
VMWARE logo press Escape and select CD-ROM to boot from it. Now wait
until it asks you to select things and selec them like this:
1 to install it on first HD

2 to partition the HD manually
y to initialize the partition table
Type the commands below:

auto hfs
update
write
quit
Then just type Y or Yes and follow through until it gives you an error
and reboots, when it does press Escape and select CD-ROM again and do
the following:

1 to install it on first HD
3 to use the existing partitions
Then press Y or Yes again and follow through and finish the
installation. After the installation select reboot and before it starts
press Stop icon on the top in VMWare.
6) Now double click on CD-ROM (IDE 1:0) and select Stuff.iso included
in Stuff.zip and press ok then start your VMWare by pressing Play icon,
let it boot then enter the login as root and then your password and type the following commands (watch carefully for spaces):
cd ../..
mkdir mnt
mkdir stuff
mount -t cd9660 /dev/disk2s0 /mnt (if this gives an error try disk1s0 or disk3s0)
cd mnt
ls (make sure you see CoreGraphics, ditto, oah750d)
cp -RLv CoreGraphics /stuff/ (only copy this if you do not have SSE3 capable cpu)
cp -RLv ditto /stuff/
cp -RLv oah750d /stuff/
After these steps type reboot and click on Stop icon before it boots again.
7) Now remember the HD Image you had before in PearPC, move that to
where you have your VMWare 4.0Gb HD Image. Look for the file with name
of the VMWare HD Image not the 4.0Gb one but the 1Kb one, I named mine
Tiger and the file is called Tiger.vmdk.
Now make a copy of this file and change its filename to anything not
too long. Edit that file in notepad and change only ONE line that looks
like
RW 8388608 FLAT “Tiger-flat.vmdk” 0
change this to
RW 6290928 FLAT “Tiger.img” 0
Make sure that if yours is not called Tiger.img you put that in there. Then save that file and go back in VMWare.
8) Now double click on CD-ROM (IDE 1:0) and select the Darwin ISO again
and press OK. Then click on “Edit Virtual Machine Settings” and click
on Hard Disk and click Add at the bottom (click Next > Hard Disk
> Use existing virtual disk > Select the new .vmdk you made few
mins ago > Finish). Now go start VMWare again by pressing Play icon
and let it boot and login to your root password.
9) At the command line type the following commands (watch carefully for spaces):

cd ../..
cd stuff
cp -RLv oah750d /Volumes/Untitled/usr/libexec/oah
(The
following ONE command is not required if you have a SSE3 capable cpu,
but all the ones below that are required no matter what)
cp
-RLv CoreGraphics
/Volumes/Untitled/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreGraphics.framework/Versions/A/

mount -t cd9660 /dev/disk2s0 /mnt (if this gives an error try disk1s0 or disk3s0)
cp -RLv /mnt/System/Library/Extensions/ApplePS2Controller.kext /Volumes/Untitled/System/Library/Extensions
cp -RLv /Volumes/Untitled/System/Library/PrivateFrameworks/Bom.framework /System/Library/PrivateFrameworks
./ditto -rsrc /Volumes/Untitled /
cd ..
DiskUtil repairPermissions /
mv /var/db/netinfo/local.nidb /var/db/netinfo/local.nidb.bad
rm /var/db/.AppleSetupDone (do not worry if this gives you an error)
reboot

Now everything is done and after reboot it should work properly. Before you reboot, make sure you make that spare HD your main one so you can boot from it. Enjoy! If theres any problem e-mail me or talk to me on irc.r-type.ca #OSx86.xplode also join #OSx86 (which is the main channel).
