I have posted a tutorial that follows my steps for a flawless Lion 10.7 fresh install here. I invite any of you to add comments or suggestions. If you have any photos that would make this tutorial better that you would like to offer, I will happily add these along with any additional information you feel is necessary.

tutorial looks good man, i'll probably have to use it as my hard drive with all my information on it died today...this month has been a bad one for my computing

you're awesome. thank you very much!

Thanks slayer. The only thing that doesn't appear to be working is sleep. I honestly found this out by mistake today when I accidentally clicked the sleep button and it wouldn't come out of it without hitting reset. It's not a feature I will use, but I would like to get it working. I just haven't looked into it yet.

xxxslayeriiixxx, I want to start getting speedstep and native power management working, but I am concerned about just jumping to Airwalk's SL method and using it for Lion. After reading Airwalk's post about power management and comparing it to my tutorial, it appears I need to do the following steps:

1. Downgrade my BIOS to E758_SZ2Z (I've already obtained those but not flashed yet).
2. Remove NullCPUPowerManagement, OpenHaltRestart, and PlatformUUID from /S/L/E folder (I already have the rest of the required kexts in use).
3. Add ssdt-1.aml and ssdt.aml to my /Extras folder.

After that, it gets a bit fuzzy. I'm not sure what to do about the smbios, boot.plist, and dsdt files. I'm currently using Airwalk's DSDT so I should be fine there. The smbios and boot.plist files you included have a lot more stuff in them, but from my minimal understanding, I don't believe it is all necessary. Here is what my files currently have in them and I have included my system specs at the bottom to see if you can help me.

Updating EVGA X58 bios...
 

Hey Guys,


It's been sometime since my bios has been updated. Curious if you guys had any suggestions for updating my bios without losing my install and my Overclock settings. Cheers

Snow Leopard 10.6.8
Intel Core i7 2.66 O/C @ 3.39
Ram 6GB
EVGA X58 Bios: SZ2S

my motherboard died and evga sent me a new board with the updated bios...i'm going to attempt to get my install back up and running this weekend and will report back

*you should be able to create a profile to backup your bios settings

So recently I tried installing SL on my computer again. I installed it from my brother's Hackintosh and then, after booting into the iAtkos L2 boot loader, I was able to actually boot right into SL.

None of my stuff worked. I installed a Realtek kext, and 1 minute later my internet was alive. Then I went and installed Chameleon 2.1 and was able to somehow inject the code for my GTX 560 (which supposedly isn't supported).

I restarted everything and then came back to find out the EFI inject worked (it started at 1920x1080, and loaded the gray Apple screen at 1080) but then it never started. I rebooted with -v and then had this error:

ACPI_SMC_PlatformPlugin --- something about Realtek RTL8139 (if I'm not mistaken) at the end.

Upon rebooting, my BIOS had been reset.

I keep trying to reinstall SL onto the hard drive using the same method as before, but I keep coming to the same damn KP.

What am I doing wrong here?

No one knows what's going on? I thought for sure that by the time I got back from vacation I'd have an answer and be able to install it again :(

Dammit! I had it installed again (except that I could not get it to work with my GTX 560) I installed Chameleon 2.1 and after rebooting, I got the most annoying goddamn error ever.

ACPI_SMC_PlatformPlugin::start blahblahblah.

FML. I can't properly install Snow Leopard or Lion anymore, and no one knows what's happening.
