fontace Posted February 22, 2008 Share Posted February 22, 2008 I know that there are lots of posts about installing and upgrading Leopard, but I wanted to contribute... Here are the main specifications of my machine: Gigabyte GA-946GMX-S2 (with latest BIOS version "F4") Chipset: Intel 946GZ / Intel ICH7 LAN: Realtek RTL8110SC Gigabit Audio: Realtek ALC888 [*]Intel Core 2 Duo E6300 @1.86 GHz [*]2 GB DDR2 667 Kingston [*]MSI GeForce 8600 GT Fanless (256 MB) [*]Seagate 250 GB SATA And here are the steps that I follow to get a fully working Leopard 10.5.2!!! Note: I recommend to boot with the flag "-v" because the system will not be able to reboot after the upgrade to 10.5.2 and until the replacement of "AppleACPIPlatfrom.kext" at the end. You will have to power off manually at each reboot when the message "MACH Reboot" is displayed. Installation of Leopard 10.5.1 with the Kalyway release, using GUID partition and Vanilla kernel Backup of one system file from "/System/Library/Extensions": AppleACPIPlatform.kext Restore of the factory settings with the Kalyway package Upgrade to 10.5.2 with the official update by following this tutorial Reboot Installation of the graphics update from Apple Reboot Installation of the NVIDIA drivers with NVInstallerv33 Reboot Restore of the previously saved ".kext" with "Kext Helper b7" + the attached "AppleSMBIOS.kext" from version 10.5.2 Patch of "AppleHDA.kext" with the great AppleHDAPatcherv1.20 from Taruga, using the attached "ALC888" codec dump Repair of file permissions with Disk Utility from Utilities Reboot... FINAL! Everything is working great with my config, including power management: sleep, restart and shutdown are even faster than under Windows Vista! Cheers! P.S.: It may also work for other Gigabyte motherboards, but I do not have AHCI on mine so you might have to backup other ".kext" files from the initial setup and restore them after the upgrade at point 10... alc888_dump.txt AppleSMBIOS_27_Default.zip Link to comment https://www.insanelymac.com/forum/topic/89391-fully-working-leopard-1052-with-a-gigabyte-motherboard/ Share on other sites More sharing options...
Charlie78 Posted February 22, 2008 Share Posted February 22, 2008 Great walkthrough. I wonder, is this applicable on the DS3P and DS4 motherboards as well?

fontace Posted February 23, 2008 Author Share Posted February 23, 2008 Yes, it might also work for other Intel-based Gigabyte motherboards.

Acidfever Posted February 23, 2008 Share Posted February 23, 2008 On my P35-DQ6 i did have some troubles with ACPI (reboot always works but shutdown is unreliable). But all the other stuff works great with 2 minor tweaks. 1. You need to install the Realtek AL889a kext 2. You need to download realteks retail ethernet driver for OSX. But besides this 100% working with Vanilla kernel (installed 10.5.2 with original updater (not from apple update), didn't use Kalyway's Combo updater but the method described here at the forum). Very happy with it and it is truly stable (have removed windows completely).
