3. Flashing the BIOS

To make OSX work on this laptop, you'll need to flash your BIOS. This can be done in windows vista, or with a USB stick.
We'll flash is using a USB stick, since some of you might not have vista.
So, format the USB stick to FAT format and copy over the BIOS file ( don't forget to extract it first!).
Then boot your laptop, hold F4 and you'll get into Asus Easy Flash Utility.
Use arrows to select your BIOS file, press enter to select it.
Make sure you have enough battery left, and don't power off the laptop until flashing the BIOS is complete.

4. Configure the BIOS to boot from DVD

Get into boot selector screen by pressing esc during Asus Logo Screen (quiet boot)
Select your DVD drive in the boot selector menu, then hit enter to boot into your install DVD.

5. Install iAtkos

Just burn the image to a dvd using your favorite ISO burning tool, burn it at a lower speed to be sure the image is burnt correctly.
Boot the laptop with the dvd, wait till installer shows up.
Go to Utilities > Disk Utility and partition your disk the way you want to, make sure MBR ( Master Boot Record ) is selected in options, but it is by default.
> Close Disk Utility, and the installer will show up.

Select:

- Patches > Remove AppleIntelCPUPowerManagement driver and thermal kexts

Don't select a bootloader, it won't work. You need the Zephyroth rev2 for the MBR. ( unless there's a better way? )

6. Install a Bootloader

As you might have noticed, your laptop now has a working OSX install but it can't boot into it without the install dvd inserted.
To fix this, you boot the Zephyroth rev2 disc.

In installer, select Bootloader -> Single Boot -> MBR ( efi v8 ) and UNCHECK all other options, don't install anything else!

7. Update to 10.5.2

Use Kalyway Combo Updater 10.5.2, after installing it will reboot a few times and stay in bootscreen for a long time, don't panic.

8. Install graphics update

Download the Leopard Graphics Update 1.0 from apple.com
Click here to Download
Install it and reboot, this will take a while but the GMAX3100 works perfectly. (no Natit needed)

9. Go Vanilla

Install vanilla kernel ( not the patched one ), then simply reboot and you're in 9.2.0.
Vanilla Kernel 9.2.0

10. Airport & Time Machine Update

To get the 9.2.2 kernel, install the Airport and Time Machine Update from apple.com
Click here to Download

11. Bluetooth, Battery, Nvidia 8400m GS, and Audio fixes

After updating, install the bluetooth, battery and Audio drivers.
Download Kext Helper b7 and use it to install the kexts.

Install powermanagement.bundle by copying it to /System/Library/SystemConfiguration/ directory.
Then reboot, and battery should be working again.

12. Yet to be fixed

DiaboliK is working on a newer driver for the nVidia 8400M GS ( the Speed mode ).
Webcam isn't working yet, no news about that. (It's a Sonix usb webcam if anyone has any clues)
WiFi driver isn't ready yet, but there's hope. ( watch The iwidarwin project )
Altho you can purchase a Dell Truemobile 1500/1505 and yor WiFi will work perfectly.
