ATI Radeaon X1800 PCIe

[shlee76]

Hi All,

 

I am new user in Mac OS.

I have installed OS X 10.6, all devices are working fine except the Graphic X1800 driver is working only on 1024*768 resolution.

 

How can I change to 1920*1200, which driver should I use?

Please help.

 

Best regards,

shlee76

Hi, I haven't specifically got a x1800 snow leopard machine but I ran an x1800 card for many years in Tiger and Leopard. I usually just had to add my device ID to the ATIRadeonX1000.kext

 

I was trying to find a tutorial for adding a device id to a kext but can't find a definitive one.

 

roughly:

 

- you are going to have to find out what your device ID is. sometime OS X will show U this under system profiler, sometimes U have to install OSX86 tools, U can use Windows and dxdiag to get device ids... U can google it and find what is best for U.

 

-drag your System/Library/Extensions/ATIRadeonX1000.kext

kext out onto your desktop.

 

-right click on kext and "show contents"

 

- open the "Contents" folder

 

- right click on Info.plist and open with TextEdit

 

- in the section that looks like this....

 

<key>IOPCIMatch</key>

<string>0x71461002 0x71421002 0x71091002 0x71C51002 0x71C01002 0x72401002 0x72491002</string>

 

add your string

 

- save and close the text document

 

- use kext helper to install back to S/L/E

 

- check permissions and clear caches and reboot.

 

Don't take my word for it. do a search for "add device ID to kext" , and read more. it has to be done right and U have to understand what you are doing.
