Help! Triple Boot Xp Ubunt OSX? {Nex To OSx}

[Gavlar]

Hey, Im completely new to the OSX scene.

I would like to install OSX on my spare 50GB partition on my HDD.
So far I have dual booted XP and Ubuntu using the Ubuntu GRUB Bootloader.

Im on an AMD Phenom II x4 CPU with ATI Radeon HD 4800 Series graphics card. (ask if you need further specs)

I would like to install OSX (Leopard or Snow leopard) and triple boot it with my XP and Ubuntu. However, since im completely new to the OSX scene I have no idea how to go about this :/

I understand that OSX isnt normally compatible with AMD or ATI but you can get it working?

Please could someone direct my to a download of an installer DVD image and instructions on how to install it?

Also, could someone inform me how to edit the GRUB Bootloader, or, could someone inform me how to scrap the GRUB Bootloader and use another one in order to Triple boot XP, Ubuntu and OSX.

Thanks alot in advance,
Gavin

I have the same problem with the new Grub2 and I can't triplee boot WinXP,Ubuntu and Zephyroth's Mac 10.5.2 Rev2 for AMD.The grub2 added the Mac's menuentry but when I try to boot it it gives me just kernel panics whatever I try to do.I tried to edit the grub.cfg file in every possible way but with no any success.But when I restore the EFI in MBR I can boot very well in WinXP and Mac,but no Ubuntu then(even with Grub2 installed in its own partition).I guess the only way is to downgrade to the grub legacy in Ubuntu and to chainload the Mac's entry manually in the boot/grub/menu.lst,like in the old fashion way.

So,I have to install chameleon bootloader in my Mac version who doesn't have it by default?

Installed chameleon v2.0 RC1 but no Ubuntu in the boot menu.Chameleon RC3 and Netkas' PC-EFI don't work on my system.I didn't try yet chameleon v2.0-RC4.Maybe the last one can see the Grub2 and ext4 filesystem now.:(

^_^So far I tried with Grub2 and Grub-legacy(0.97) from Ubuntu to boot Mac too in all the possible and impossible ways and still nothing.Purely and simply I can't multiboot on my old system,I just can't have them all together.
It's for the first time when I give up for something.I'll try later when I'll buy a new system for me.:mad:
Edit:Finally got it with Grub2 adding this entry in the grub.cfg file by grub custom_d40 file:
menuentry "MacOSX". {
insmod hfsplus
set root=(hd0,8)
multiboot /boot
}
By this entry it starts the Mac's bootloader first,in my case chameleon2rc1 from where I can boot the Mac now.
