    Default Radeon 7500 Graphics card, please help!

    Hi,
    I have an IBM R50 with a ATI Mobility Radeon 7500 Graphics card. My computer recognizes the card, but it doesn't give me quartz extreme.
    When I go into system profiler under "Graphics/Display" This is what it says:

    __________________________________________________

    Radeon Mobility 7500:

    Chipset Model: Radeon Mobility 7500
    Type: Display
    Bus: AGP
    VRAM (Total): 32 MB
    Vendor: ATI (0x1002)
    Device ID: 0x4c57
    Revision ID: 0x0000
    Displays:
    Color LCD:
    Resolution: 1024 x 768 @ 60 Hz
    Depth: 32-bit Color
    Core Image: Software
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Quartz Extreme: Not Supported

    If you could help me get QE working so I could use my dvd player, imovie, idvd, chess, etc... that would me AMAZING!
    Please help me figure this out.

    Thanks a ton,

    -David

    Follow the instructions below:


    1. First, you need to download the file pack Here. Extract it as-is on the desktop somewhere.

    2. Open a terminal.

    3. Do this: sudo rm -r /System/Library/Extensions/ATI*
    This removes the old drivers.

    4. Drag and drop all the files from my Extensions folder you just downloaded into yours, authenticating when prompted.

    5. Hit the back button in the finder, and open the Frameworks folder.

    6. do this in the terminal: sudo rm -r /System/Library/Frameworks/OpenGL*

    7. Drag and drop the new OpenGL file into Extensions.

    8. Now it gets tricky: You need to duplicate some of the instructions from the original 7500 pack I got these files from (unfortuately, the original pack's instructions are incomplete)

    "Instructions:

    1. Run the Installer Package. Do NOT reboot yet.
    2. Open Terminal and enter in the following

    ioreg -l

    1. Locate AGP in the output. It will most likely be listed as AGP@1, but your machine may differ. You will see "compatible" = <"pcixxxx,xxxx","pciclass,xxxxxx">

    The first set is the item you should note.
    Enter the following at Terminal:

    sudo nano /System/Library/Extensions/AGPGart.kext

    Locate:

    <key>IONameMatch</key>
    <array>
    <string>pci8086,2561</string>
    </array>

    Change this to reflect the information you got above.

    cntrl-o, enter, cntrl-x

    Now enter the following at the Terminal prompt:

    sudo chown -R root:wheel /System/Library/Extensions/AGPGart.kext
    sudo chmod -R 755 /System/Library/Extensions/AGPGart.kext

    Now enter the following at the Terminal:

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

    Add the following in the middle somewhere after the Kernel key, but before a Quiet Boot or Boot Graphics key.

    <key>Kernel Flags</key>
    <string>-f</string>

    cntrl-o, enter, cntrl-x

    Now open Disk Utility to be safe (this stepp is not required, but highly recommended) and run Repair Permissions on your disk."

    9. Now that you've done all that, there' still one more step, which I learned from 7500-working.doc, found on these forums.

    "First, open up a terminal session and go to the location of those temporay files, and tweak the contents of the AGPGART package. Go to AGPGART.kext/Contents/Info.plist and edit it as root. (sudo nano Info.plist) ??We want the kernel to recognize the 855PM GART interface as the AGP GART. ?Look for the line beneath IONameMatch that reads pci8086,2561. It should now be pci8086,3341. (Thinkpad T30 or Dell C640 users with the i845MP should use pci8086,1a31 instead.??Save it. (Use Ctrl-X, y to save and exit)"


    Once all this jazz is taken care of, it's time to make doubly sure the permissions are right.

    10. Do this in terminal:

    cd /System/Library/Extensions/
    sudo chown -R root:wheel *.kext?sudo chmod -R 755 *.kext?sudo chown -R root:wheel *.plugin?sudo chmod -R 755 *.plugin
    cd /System/Library/Frameworks/?sudo chown -R root:wheel OpenGL.Framework?sudo chmod -R 755 OpenGL.Framework

    reboot!

    I hope this can help you!

    Hi,
    First off, I really apreciate your help so far.

    Ok, so, I downloaded the zip file and got to step 7 and realized a problem..
    There is nothing in the "Frameworks" folder and in the "Extensions" folder there is only one file caled "Radeon Tool".
    The instructions tell me to "Drag and drop the new OpenGL file into Extensions." and since nothing in that folder is there.... No can do

    Please let me know if im doing something wrong... or what I need to do to get this working.

    Thanks!

    -David

    hmmm.... I followed all of the steps and it screwed my computer. I had to reinstall mac
    Maybe it has something to do with the fact that im running 10.5.1 and he had 10.4....?

    Anyone more ideas? I have searched all over the web trying to figure this out...and I still can't get it. and since i'm a newbie to this whole hackintosh thing, I need to get instructed on a somewhat easy-to-do basis...

    Any help is GREATLY apreciated,

    Thanks!

    -David
