You will need:

1. SSE2/SSE3 enabled processor: Download WCPUID application and run it. See if your processor is supported.
2. Mac OSx86 'Deadmoo' image: If you can find it, then you can install it. Google for torrent and pheNIX. Find the Marklar-Tiger.dmg. A .dmg file is a disk image of Mac OS X.
3. DVD Burner and DVD ROM
4. UltraISO: Download it from here. Trial version works for us.
5. A Patch :) - Google for Generic_OSx86_Install_DVD_Patcher_Release1.rar and download this file.
6. Partition Magic (or any other partitioning software)
7. Windows bootable disc: Your Win XP installation CD works and we need this just to be on the safe side.


Creating the DVD:
After downloading the DVD image, convert the .dmg file into an .iso file using Ultraiso. Launch Ultraiso, go to tools, select convert. Find the .dmg file and save it as an .iso file.

Unrar the patch file (point 5 - see above) and Marklar-Tiger-patch-release1 file inside the original rar file. Run ppf-o-matic3 and select the newly created .iso file and select Marklar-Tiger-patch-release1.ppf file in the Marklar-Tiger-patch-release1 folder. Click on the Apply button. Now you have a patched version, that should install on most hardwares although you would still need SSE2/SSE3 enabled processors.

Now burn the .iso file onto a blank DVD.

Creating Partitions:
Make sure you have two partitions and also make sure that the Mac OSx86 partition has more than 6 GB in it. If you already have this setup and Win XP installed, then you can proceed to the installation step. Otherwise, you can google for creating two partitions using Partition magic. This is basic stuff and anyone should be able to do it.

Installation:
Insert the burnt DVD in your DVD ROM. Make sure your BIOS is able to boot from DVD before a hard disk. Now you will be presented with a boot menu, that looks something like this:

Press enter to proceed. After the spining ball, you should see the Mac OS X installation setup.

Click on Utilities in the top menu and select Disk Utility. This would show you two partitions in it. Select the non-WinXP partition and format it as Mac OS Extended (journaled) - PLEASE NOTE: Make sure you select the correct partition. If you don't (and in some cases, even if you do) you might lose all stuff on the hard disk, so be very CAREFUL. Don't blame me, if you lose data or if your computer starts acting wierd.

Once you have completed the formating of the partition, you can quit Disk Utility (press alt-Q on the keyboard). Now you will be back in the setup. Now you can simply do a next, next, next to complete the installation. Advanced users can choose not to install printer drivers by clicking on the customize button during the setup. Once, your installation is complete, your computer would reboot.

Boot from the Mac OSx86 DVD again and hit enter at the boot menu. When the Mac OS X setup starts again, goto Utilities (in the top menu) and select Startup Disk. It would show three disks - Win XP Partition, Mac OSX Partition and the DVD Drive (your options might differ). Select the Win XP partition and reboot the computer. Remove the Mac OSx86 DVD and let your computer boot normally. Now, your computer would boot into Windows XP. Login with an administrator account. Goto Start menu --> Run --> Type "compmgmt.msc" and hit enter. In the left hand column, under the storage menu, select 'Disk management'. Now right-click on your WinXP partition (most probably C drive) and select 'Mark partition as active'. The last step allows you to boot to Windows XP without a bootable disk.

Now go to 'Start Menu' --> Run --> type 'cmd.exe' and hit enter. Now type the following:
1. c: [hit enter]
2. cd \ [hit enter]
3. debug.exe [hit enter]

Now paste the following:

Now close the command-prompt window and open up C:\boot.ini in notepad. At the end, add this line:
c:\CHAIN0="Apple Mac OS X x86"
Save and close the file now.

Now you should have a dual-booting machine with Win XP and Mac OS X on it. When you will boot your machine, you will be presented with two operating systems. Note: If you select 'Apple Mac OS X x86', it will give you another boot menu. In this boot menu, you will have to select Mac OS X again, otherwise it would move back to the first boot menu.

If this breaks your computer somehow, please don't blame me. This set up worked perfectly for me and in most cases it should work for you too. If you are stuck and need help, google the error message or the problem you are encountering. You will find a lot of information at osx86project.org and their wiki site. If everything fails, drop me an email and I can try to help you out. If the problem is trivial and easy to solve, I might not reply to your email. I do welcome feedback.

PS: You will find some more screenshots and photos below, in my last post.

And this time, I was successful in installing Mac OS X on my work IBM Thinkpad R50e - hence, a Mactel (Mac - intel). It is a dualboot machine with Win XP and Mac OS X. I, originally, had Win XP and (K)Ubuntu on this machine, but for the sake of science, I decided to put OSx86 on the (K)Ubuntu partition. I am attaching some screenshots for interested parties. Feast your eyes, ladies and gentleman:



























I will write more about once, I have more time.
