Couple of hours more on it and now it works!!!
I've used a great guide from sk1nhd33t about installing SL on GA-G31M-ES2L.

http://www.infinitemac.com/f57/guide...or-g31m-t3672/

I'm fine tuning it but same problems of you about restarting/shutting down after sleep (with NullCPUPowerManagement and SleepEnabler)

TBH I never had any success with USB drive booting SL on the gene. I tried pretty much the same steps and it would always hang for me also. In my experience SL installer needs to be run from inside target Leopard environment, although posts in this forum seem to suggest otherwise. I've also been saving a draft guide in my blog for this rig, will try to publish it soon.

Posted a little and simple guide to install SL on osx86 wiki HCL::
http://wiki.osx86project.org/wiki/in...CL_10.6.1#Asus

sweet thanks for the post on the wiki, it helped alot, finally got it running.

Some news:
- NullCPUPowerManagement.kext
- OpenHaltRestart.kext
- Sleepenabler.kext
I've installed an hardware monitor application and the system run smooth at 3.4ghz with cpu max temp 66 degrees when in full load. In this condition the only thing doesn't work is the wake up after sleep (one time works and one not)
Without the three kexts up all works fine but the max temp in load is over 80 degrees... and the system low down its frequency (drop down performance)
Is there a way to solve my stop problem? I can't image to restart and shutdown the system every time I need it...

When I was outfitting my MBP with an optical bay SSD, I had to disable hibernation. Otherwise, my system wouldn't wake properly and I would have to do a hard shut down and reboot. After executing "sudo pmset -a hibernatemode 0" in the terminal, this stopped happening. This kills hibernation, something I very rarely need and can work around.

I don't know if these kinds of settings are taken for granted in the OSx86 community but I am yet to see that anywhere. I'm sure it has been tried and tested, but I just though it may help if otherwise.

My 2¢...

krofa.

p.s. I am also shopping for a mobo and came accross this post when I was searching for the Rampage II Gene...

I managed to upgrade my Gene setup to 10.6.2 without any problems via the instructions on Netkas's site. I just replaced my version of SleepEnabler.kext I was using with the one he posted. I upgraded to FakeSMC 2.5 and PC EFI 10.5. Everything works great, but still no sleep after a restart .

Asus Rampage II Gene Rev 904: Intel Core i7 920 3.2GHz, 6 Gb DDR3 RAM, Apple OSX 10.6.1 Snow Leopard

I also have the restart after sleep problem with my Asus Rampage II Gene based hack.

I have done some brief tests replacing OpenHaltRestart.kext with Master Chief's OSXRestart.kext (http://www.insanelymac.com/forum/ind...owtopic=199048).

Restart after sleep works with this setup but now the computer doesn't shutdown fully. I suspect that there are further changes needed with the DSDT and/or kexts in order for shutdown to work with OSXRestart.kext.

Hi JDC1001:

This question has nothing to do with the subject, but could you tell me what Video card do you have with this mobo? I'm looking to install this mobo in my Gateway FX6800 with the stock ATI HD4850 512MB 2dvi.

Thanks,

I also been trying to figure out how to install OSX on this motherboard:
I got
- Intel i7 930
- Asus Rampage Gene II (BIOS 0904)
- WD Black 750 GB Sata HDD (1 Partition GUID) -- Plugged in to SATA 1 Port
- Sata DVD-RW DL drive -- Plugged in into SATA 3 Port
- 6 Gig DDR3
- Visiontek 4870 512MB Video Card
- USB Caddy with 80 GB HDD on it.

I also own a macbook pro to format the hdd and restore disk image to the 80GB HDD.

I tried the guide from this page: http://www.insanelymac.com/forum/ind...owtopic=194312
but every time i tried installing, always stuck at Waiting for Root device (when i use -v cpus=1 busratio=20), if i just let it run, it stuck at the spinning wheel.

Any help ? maybe BIOS Settings ?

PS: I also tried booting using Empire EFI (latest version), and using myHack boot, but still never could get into the OSX Installation page.

Also, just to make sure, for the DSDT.aml, I can just copy and paste to the "restored OSX" and don't need special way to patch/install it.

Thanks
