So I went through the following steps to get updated to 10.5.6. I'm currently on 10.5.5 using medevil's nforce kext named AppleNForceATA.kext.

 

1. Downloaded UInstaller and installed PC EFI v9 with the options selected:

-set boot timeout to 5 seconds

-set native resolution to my monitor's native resolution

-Install PC EFI v9 Chameleon Edition 1.0.12

-Apply Ethernet EFI String (time machine fix)

-Apply EFI String for video card (selected NVidia 8600GTS 256MB)

2. Downloaded voodoo 9.5.0 version 1.0 kernel and installed it with the default options selected

3. Rebooted and system came up fine

4. Downloaded 10.5.6 Desktop Delta Update

5. Opened up terminal and backed up 10.5.5 extensions

# sudo -s

# mkdir -p /1055extensions

# cp -R /System/Library/Extensions/* /1055extensions/

6. In the terminal now run this command and let it run

# while sleep 1 ; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext ; done

7. Started install of 10.5.6 and waited for it to finish. Didn't press restart yet.

8. Went back to the terminal I had opened and pressed ctrl+c to stop it from running.

9. Edited /System/InstallAtStartup/scripts/1 and took out /System/Library/Extensions/Dont Steal Mac OS X.kext replacing with /System/Library/Extensions/dsmos.kext

10. Copied over seatbelt.kext from 10.5.5 extensions but backed up new one first in terminal so I can mount dmg files in 10.5.6 again

# mkdir -p /1056extensions-original

# cp -R /System/Library/Extensions/seatbelt.kext /1056extensions-original/

# cp -R /1055extensions/seatbelt.kext /System/Library/Extensions/

11. Backed up /System/Library/Extensions/AppleAHCIPort.kext

# cp -R /System/Library/Extensions/AppleAHCIPort.kext /1056extensions-original/

12. Then edited /System/Library/Extensions/AppleAHCIPort.kext/Contents/Info.plist and took out the section for the MCP79 chipset since if I leave that in, it doesn't use the AppleNForceATA.kext and the result is that it can't find the root drive.

12. Then exit terminal and press the restart button on the 10.5.6 install window.

 

The end result is that it does load the proper kext, the AppleNForceATA.kext but then I get one warning of phy has been reset but it does find the boot drive. Then I get an error message of data underrun error I think is what it said and it doesn't go past that.

 

Anyone know how to fix this?
