In Topic: [How To] Install Leopard Retail DVD on ASUS P6T Deluxe LGA 1366 (core i7)

07 June 2009 - 05:53 AM

ok i thought i had everything going 100% or so it seemed

well i thought the mouse stuttering was just due to my wireless kb/m but alas it wasnt
and that was just the domino effect, i use a Line6 Toneport for audio as well as guitar modeling
and whenever any audio gets used whether it be youtube, guitar pro, itunes, etc it has a horible stuttering lag clip whatever you want to call it. is this a usb issue? ive done alot of searching to only have no avail. im running a Asus Rampage II Extreme, dont have the riser sound card (bought open box, just the board). and ive been using on my windows installs. i could even live with the stuttering mouse (but would be nice to fix) but the usb sound is a big problem :( does anyone have any ideas?

I was able to get 10.5.7 working on my Asus Rampage II Extreme Core i7 920 system with some help for your guide.

You're right, much of it is outdated and a 10.5.7 Core i7 guide would be useful to a lot of people. I suppose I could write one and host up some files. The thing that bothers me though is that everyone wants to know exactly what to type, but they don't want to know why they have to type it. I don't know if I want to get into the business of spoon feeding a step by step guide to people who don't want to learn.

That issue aside, here is a basic overview of what I've done. If anyone has successfully installed with your guide should be able to follow this.

1) Setup your bios as described in the guide. It is crucial that you disable hyperthreading and activate only 1 core.

1) Boot from v3 slimbuild image available in this thread, and install with a Leopard retail disc. I used the disc I bought the day Leopard was released, and is version 10.5.0. Anything up to ~10.5.5 should work. There is an incompatibility with the seatbelt.kext on the slimbuild boot image and 10.5.6. More about that in a bit.

2) Leopard will "fail" install at the very last moment due to not being able to activate the installation partition. Ignore this and reboot with the slimbuild disc, this time booting from the hard disk partition instead of your Leopard disc. i.e. bt(0,0)/mach_kernel.voodoo busratio=20 -v -f rd=disk0s2.

3) Finish installation. Now you've got a Leopard desktop. At this point I modified the kext in /S/L/E/IONetworkingfamily.kext/Content/Plugins/AppleYukon2.kext/Content/Info.plist as stated in your guide.

Note: You do not *have* to boot with -f. I had problems getting the kext change to be noticed by the system. In order to fix that you can use the touch command. Touch updates the last modified time of the file/directory. There is a process running in OSX that recognizes when this folder has been changed and automatically rebuilds the kext cache for you. This can be accomplished with 'sudo touch /System/Library/Extensions'. You may also want to touch the actual AppleYukon2.kext as well just to be sure. 'touch /System/Library/Extensions/IONetworkingfamily.kext/Contents/Plugins/AppleYukon2.kext'

4) Download combo updaters from apple.com for both 10.5.6 and 10.5.7. This is necessary because I installed from the 10.5.0 installation DVD. The 10.5.7 updater requires that you are already running at least 10.5.4. If you installed from a newer installation DVD than I did, you could theoretically skip straight to the 10.5.7 combo updater.

Important: Once you download the combo updaters, mount both disk images and copy the combo updater .pkg file out of them and into a safe place. Remember that seatbelt.kext incompatibility with 10.5.6 I mentioned earlier? If you don't do this you'll just get a kernel panic every time you try to mount the 10.5.7 updater image from 10.5.6.

5) Install the 10.5.6 updater and reboot. Boot from the slimbuild disc again. The first time you boot the system will do some things, and then reboot on it's own. A lot of people refer to this as a failure, but it's part of the combo updater process. My genuine Mac Pro does the same thing when being updated. It's just part of the process.

Reboot the second time and you should be back at the desktop. It might take a while to boot at this point, and you won't have any network interfaces again. This is because the 10.5.6 updater overwrote your kext changes to AppleYukon2.kext.

From here you have a few things left to do and the order doesn't matter too much;

5b) Run the dsdt patcher as described in the guide. In order to get it to work, I had to use the -f flag. i.e. 'DSDT\ Patcher -f', then 'DSDT\ Patcher -f Debug/dsdt.dsl'. Copy the dsdt.aml file to /DSDT.aml and you're done.

5c) Re-patch the ethernet Yukon2 kext if you need to download something.

5d) Install the 10.5.7 combo updater.

6) Install Chameleon 2 RC1 431. This is a point-click-ship affair, all you have to do is double click the icon and hit continue a couple times. Chameleon creates a directory called /Extra off your root. The only thing that really *has* to be there to boot the vanilla 10.5.7 kernel (which is what you want) is the dsmos.kext and the injector kexts automatically installed by Chameleon. You can experiment with different kernel extensions from the EFI_Pack attached to this guide.

I myself am using;

a) the 3 injector kexts installed by Chameleon
B) dsmos.kext
c) AppleSMBIOSEFI.kext

7) Reboot your computer and enable all cores + hyperthreading in the bios. This time boot from Chameleon, just hit enter on the Apple option.

7a) You'll need to re-patch your Yukon2 kext for networking again since the 10.5.7 updater overwrote your changes. Use the touch method to update the cache and/or reboot.

7b) Install the AppleHDA.kext as per the guide for sound. You can use the touch method described earlier to bring up audio without even having to reboot.

7c) If you have problems with kexts or getting hardware to work, go to the /Extra/com.apple.Boot.plist and add the flags -v -f to the flags section of the file. This will force chameleon to boot with -v -f when you select normal bootup. Remove those options once you have things working the way you want.

That's about it. I could go more in depth if necessary, or create a new thread I suppose with more detailed information. I learned a lot of things along the way that people might find useful. It's probably a good idea to get it documented before I forget it all.


thank you thank you thank you thank you!
