OS X 10.4.8 on T60

Finally, I got Tiger run on my T60. (Intel Core 2 duo 2.0G 1G, 100G HD, ATI x1400, SoundMax card. IPW3945 INTERL PRO 1000 )

so far, only need to find driver for IPW3945, everything works fine.


here is little work for Graphic Card and Sound card.

Graphic X1400

Edit /System/Library/Preferences/SystemConfiguration/com.apple.Boot.plist , add two lines

Graphics Mode
1400x1050@60
below
Boot Graphics
Yes

and edit System/Library/Extensions/ATIRadeonX1000.kext/Contents/Info.plist, adding Dev ID of your card (7145 for X1400)
IOPCIMatch
0x71451002
to enable CI/QE support

SoundMax card

Delete AppleHDA.ket
install azaliz.audio.pkg
edit /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/Info.plist
change IOHDAudioCodecVendorID value to 0x11d41986
edit /System/Library/Extensions/AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist
change IOPCIPrimaryMatch value to 0x27d88086.

and then fix permissions, clear kext cache
sudo diskutil repairpermissions /
sudo rm /System/Library/Extensions.*
sudo kextload AppleAzaliaAudio.kext
sudo kextcache -k /System/Library/Extensions/

reboot you should got 1400*1050 resolution and sound card work.
