Thought I'd Chime in seeing as I stumbled upon this post and would like to help...
8930-A41 Model. 15'4. x3100.
Bought off ebay for £50.00 as it was a Celeron and could be upgraded easily to T9300 2.5 6MB Cache with Middletons Bios.
My steps were simple.
Perform the Middleton Bios Upgrade, Install T9300, install SSD and 2X4gb ddr2 667.
Iatkos Lion: This was preferred as it had already support for my touchpad in the install screens and could perform a base install of 10.7.2.
Keyboard + Mouse and Working Wireless.
I ensured the defaults were checked but made sure the boot option was set to 32bit with a 32bit TSCSync.
No sound, ethernet, wireless or graphics options set as I knew this machine was fussy and had my own to put in place.
We Just want to get through the install and to the desktop....
You will be without ethernet, sound and keyboard+mouse. Get a wired usb keyboard and mouse.
You may have a really laggy experience first boot, the goal of this is to get the extensions in to repair the lag and get past the quirks of a bare system with no support as of yet.
Get to the desktop install 10.7.5 and reboot…
Ok now copy my Tools folder to Utilities...
(I hope you have a working wireless for this part)
Run Champlist in tools to update Chameleon. Nothing more.
Copy Contents of Extra folder to Extra, or make Extra folder in your HDD if not there.
Delete AppleHDA.kext from your HDD's S/L/E
Now open Tools in the Utilities folder, run Kext Wizard.
Install contents of System/Library/Extensions to your HDD's /S/L/E.
Dont Close Kext Wizard.
Now install ps2.pkg in working mouse folder.
Back in Maintenance Wizard section of Kext Wizard:
Make sure repairing Extra and S/L/E is all checked and run and wait.
Once done run applejack installer and reboot into single user mode:
type in command line:
applejack auto reboot
reboot into a working R61 10.7.5 system.
What Doesn't work (So Far).
Sleep. < Need to research unloading possible problematic kexts.
Display Brightness (But I think I can fix this).
My System is a very basic model as I know bluetooth is an issue in osx86 and didnt want to have an always on device draining battery. I have a usb dongle in my ultrabay and that suffices my needs. This model has no fingerprint reader. The Wireless card is a swap out from an old macbook pro core2duo.
I am pretty sure between us all we could make this work easy enough, I am happy on mine at present and have not really had any big issues. I am just currently trying to stop the tap to click behaviour thats all
Included is some apps to help through the installer and later on perhaps.
Happy Hackintoshing R61'ers!
