Thread: [GUIDE] OS X Lion on ECS 945GCT-M2 Mobo

In this short guide I will explain you how to install Mac OS X on old Elitegroup ECS 945GCT-M2/1333 (v1.0a) motherboard with Pentium Dual CPU which are 100% compactible. Check my signature for my full system spec!

For this guide, I will use OS X Lion distribution - iAtkos L2 (search on google for download).
After you downloaded iAtkos L2, burn it to DVD with CDBurnerXP .
Now you have successfully burned iAtkos L2 to DVD!
*Here starts booting & installation*
- Put DVD in your CD/DVD drive and restart your PC.
- Press F8 and select CD/DVD drive to boot from it.
- When you see small countdown bar of iAtkos L2 install press F8 and type in cpus=1 to prevent some issues during installation and slap ENTER on keyboard to proceed(not necessary, but I did it).
- After few minutes Language selection should pop out, choose your language and click on the arrow (which means "Next")
- Go to top menu and go to "Utilities", than "Disk utility".
Select your Hard Disk, click "Partition" and for "Volume scheme" set "1 partition".
Name it "OS X Lion" and for "Format" select "Mac OS Extended (Journaled)" and click Apply.
- Close Disk Utility.
- Click "Continue".
- Click "Agree".
- Now, select your "OS X Lion" disk and click "CUSTOMIZE". See this picture below to see what patches/drives you will need.
CLICK HERE TO SEE CUSTOMIZE OPTIONS
- Now click "Install".
- After about 30 minutes installation of OS X should be done, click "Restart" or wait 10 seconds, it will restart automatically.
- Now you should see Chameleon Bootloader, it will countdown 5 sec. till it starts OS X. After countdown, you should see Apple logo. (if you stuck at Apple logo, at Chamelon countdown thing press any key and type -v to boot with verbose mode to see what is problem.)
- After Apple logo, Apple account setup should pop-out (select country,timezone,account name, etc...)
- You are at desktop of your freshly installed OS X Lion!

Now you should search kexts for audio, graphics card...
After you all got ready, enjoy your OS X !
Feel free to update to 10.7.4!

For network, You have to delete IONetworkingFamily.Kext from S/L/E (make backup of it) and install modified IONetworkingFamily.Kext with KextUtility.

Manwex:

I have the ECS 945GCT-M V2 with a 1088 FSB.
Core 2 Duo E6400.
Runs Snow Leopard.

Have you tried to load Mountain Lion yet?

Thanks

Sure, it runs pretty good, I didn't had any crashes or kernel panics.
I made small video few months ago, you can watch it here:

Hey:

Thanks for getting back with me.
I am stuck trying to boot to install.

Can you share with me what bios you have
and what changes you made to get running?

Also, what method did you use to run ML?

Thanks Man

I have default BIOS, nothing updated. Just make sure you set Disable Execute bit to Enable in BIOS.
I installed OS X ML using Niresh12495's distro. I suggest you to wait for iAtkos ML (it is coming this month) and install it on your PC.

Tried your guide for iATKOS L2 but keep experiencing shutdown while installing to the hard drive.
I get to 13 minutes left then suddenly the machine dies. Thought it was overheating but it runs
Window 7 just fine.

Any ideas?

Have you tried to boot iAtkos L2 with -v npci=0x3000 cpus=1 boot flags ?
I never had shutdown while installing.

Hey:

I was having an overheating problem with the Mobo. Fixed that and
have a good basic Lion install.

Thanks for your help!
