We left off part 1 with a running system. Complete parts were assembled and a guest OS, either Windows or Linux, was installed to test the system components and make sure everything was running. Now on to OS X.

The ex58 chip set is not supported under Leopard 10.5.0 and our installation DVD is 10.5.0 so we can not just install leopard as we did previously with our EP45 build. Here we need a different route. First let us gather our parts.

Steps:

First we connect the hard drive we want to install leopard on to our working Mac system. You can accomplish this by directly connect to any available SATA port or to the USB to eSATA dongle to your laptop. Open up disk utility from Applications/Utilities and select the disk you have connected. Then Click on the Partition tap and select your desired partition scheme. For our drive we selected 1 Partition.

Put a name for it and make sure it says Mac OS Extended (Journaled) in the format drop down menu.
Now click on options and button and make sure that the GUID partition option is selected and then click OK. Click Apply and Disk Utility will start format the drive according to our selections.

Now we need to install Leopard on our fresh new drive. We start by inserting our Leopard DVD into our working Mac laptop or desktop and it should pop up a windows with an icon that says Install OS X. Fire up terminal from Applications/Utilities and type the following: Note that each line is separate.

cd /Volumes/Mac\ OS\ X\ Install\ DVD/
cd System/Installation/Packages/
open .


A finder windows will pop up with lots of packages to choose from.
We need only one, the OSInstall.mpkg. Double click on that file and it will start the Mac OS X Installer. We go through the option we want and when you get to the destination part we simply select the hard drive we prepared earlier. About 20 minutes later we have Leopard 10.5.0 installed on our fresh drive. Now we find the Combo updater we downloaded and double click on the dmg file, and run the installer but also making sure to select our fresh drive as our destination.

Final steps:
After the OSX installer and the combo updater we now have 10.5.7 or 10.5.8 depending on your selection installed and ready to boot. If you remember correctly, our build used eVGA Nvidia GeForce GTX275 and so we need to install the correct drivers for it. Navigate you browser to the Nvidia’s site to download these drivers or to eVGA’s site. We used these ones here from eVGA. Double click to mount the dmg and install the drivers.

Now we shutdown the mac and remove the hard drive and install it in our build machine. We also plug the EFIX(tm) Module in the first USB header. Booted up the machine and went into bios to set the EFIX(tm) to boot first and we have a working Mac.

Problems:
The X58 chipset and the core i7 for some reason run the clock fast when booting with EFIX(tm) version 1 but not with version 1.1. So if it is 9:00 pm in about 2 minutes real time it would be 9:04 and not 9:02 so time is twice as fast. This messes up a lot of programs like Growl and QuickTime.

In Part 3 we get rid of EFIX(tm).
