ATI Radeon drivers?

[idumych]

I have an ATI Mobility Radeon 7500, and although the video quality in quicktime is pretty darn spiffy, I can’t get VLC to work, and Apple DVD player has serious artifacts in the video. I figured out by reading the forums and wiki that this is because I don’t have a real driver installed for my card, and therefore open gl isn’t working. I saw an article on the wiki that said there is a way to get the ktext files for the radeon from OSX 10.1.1, but the article also said this was outdated info and Radeons were supported in 10.4.3. I installed from an unknown DVD with Maxxus’s cracks and OSX 10.4.4, and I still don’t have support. Would someone be willing to send me the necessary ktext files? If you have them on a website please PM the link to me, otherwise my email is idumych AT gmail DOT com.

Thanks a buch, I appreciate your patience and insight.

Here is a log of every install action I have taken, for troubleshooting purposes.

 

First, I installed the OS on my hard drive from a cracked DVD. It is Mac OSX 10.4.4 with Maxxus's patches.

 

Then I installed the Radeon 7500 pack PGK. It installed successfully. I saw in the readme that I should not reboot yet, so I wont.

 

I run ioreg -l and look for the AGP

 

I found the AGP entry and checked the "compatible" part:

 

"compatible" = <"pci8086,1a31","pciclass,060400">

 

Then I entered "sudo su" because I'm too lazy to type sudo all the time

 

I used nano to edit AGPGart.ktext, but realized it's a folder. I assume they meant /System/Library/Extensions/AGPGart.kext/Contents/Info.plist

 

I found the following section , and edited it to match my AGP

 

<key>IONameMatch</key>

<array>

<string>pci8086,2561</string>

</array>

 

I changed the value to

 

<key>IONameMatch</key>

<array>

<string>pci8086,1a31</string>

</array>

 

, which matches my card, and saved the modified file.

 

I then ran the following commands:

 

chown -R root:wheel /System/Library/Extensions/AGPGart.kext

chmod -R 755 /System/Library/Extensions/AGPGart.kext

 

After than I ran the next command:

 

nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

 

I changed the kernel flag to -f and saved the file.

 

The next step in the readme is to reboot, but I saw in the radeon package post that I need to swap the callisto.ktext with the 006 build, so I did so. I think I ought to change the CallistoHAL file to reflect my card's device ID, but I'll just stick to the instructions for now.

 

I repaired permissions as suggested and rebooted.

 

I changed the pcimatch string to

 

<string>0x1a311002&0xffffffff</string>

 

this reflects the value I used in the driver, let's see if this does the trick.

 

After rebooting, there is still no QE. I'll try changing the CallistoHAL to use my Video Card's dev id instead.

 

changed the string to: <string>0x4c571002&0xffffffff</string>

 

even after changing the file, there is still no QE support.

 

I also noticed that if I try to change the resolution it causes massive video distortion and system lockup.

 

I checked to make sure that CallistoFB is set as the fb provider in the driver ktext I have, and it is, so I've run out of ideas.

I changed the pcimatch string to

 

<string>0x1a311002&0xffffffff</string>

 

this reflects the value I used in the driver, let's see if this does the trick.

This pcimatch has the value 1002 whereas the previous one had 8086.

 

1002 is ATI - your video card

8086 is Intel - some controller card, probably for AGP

 

I really believe that 0x1a311002 should reflect your video card device id ---> 0x4c571002, not some hybrid of some AGP controller card and video card ids.

 

Also, the "&0xffffffff" is used to specify a range of device id's instead of just one. If you are hardwiring the info.plist for just your card, you can remove that.

 

<string>0x4c571002&0xffffffff</string> ---> <string>0x4c571002</string>

Thanks as always, ramjet, I'll try that tonight.

Ok, I tried it, and it didn't work. Now my system is totally inoperable, I just get the apple logo stuck on the screen and a mouse cursor
