Hi man i've problem to start snow leopard with this card, i've found one method that i think may work but links are dead, this is that i've found:

 

Firstly, delete all ATI related kexts from /S/L/E. They're all kexts starting with "ATI" and also natit.kext.

For my Sapphire HD4850 Dual Slot, I've installed the kexts in this sequence (after deleting all ATI kexts):

1. MacOSX_10.5.6_radeon_hd_48x0_drivers.pkg http://osx86.radeonhd.eu/?file=8&sort=2

2. Patched framebuffers for 48x0 and 3870x2.pkg http://rapidshare.de/files/47144314/patched_files.zip.html (from #radeonhd channel in irc.osx86.hu)

3. Natit.pkg http://rapidshare.de/files/47140358/Natit.pkg.html

 

Install them in that sequence and only reboot after installation of 3rd package (Natit.pkg).

 

It's VERY IMPORTANT that you delete the ATI related kexts from /S/L/E folder before installing those packages. For some reason, if I install them without deleting the kexts from /S/L/E before, I couldn't boot (black screen) to Leopard. I think there's some kext (that is not part of the packages) conflicting with the patched ones. First Question: how about ati kext to delete?? which files??

 

Second Question: where can I find that files?? Link are deads!!!

 

Thanks a lot...

This one worked for me... follow in the right order...

 

Based on Article- http://www.insanelymac.com/forum/index.php?showtopic=155477

 

Boot with -s, and do the following commands:

/sbin/mount -uw /

cd /system/library/extensions

rm -r ATI*

rm -r natit.kext*

Reboot with -f -v.

 

Run the installation package 7_radeon_hd_48x0_drivers.pkg

Install ATY_Motmot.kext with Kext Helper (important)

Reboot -f -v

 

If you have the bug - Bouncy Screen.

Downloaded Package Natit_no_powerplay_4800_4600.pkg and install it.

 

 

If you have the bug - Black Screen during Change of resolution.

Downloaded Natit_with_4850_bios_inside-1.pkg, install, reboot.

 

Driver worked perfectly.... ofcourse I spent like 2 days finding the right driver.... I would have gotten alot more sleep if I found this post earlier!! it even recognized my Monitor and has the name displayed perfectly, and also probably have the right driver/settings for it because the font is nice and crisp.

 

Hope it works for you. Good luck.
