Maximus Formula II + 4870 Snow leopard KP - Help!

Hi,

 

I've been following this tutorial on installing snow leopard on my Maximus formula II + 4870 and 2GB Ram:

 

http://www.insanelymac.com/forum/index.php...p;mode=threaded

 

Basically I followed the tutorial, edited my boot.plist to GraphicsEnabler=yes for my GPU as suggested on various threads, so now using a mac laptop and external HD I installed a retail mac version onto the portable hard drive, made the edits to it following the tutorial via the mac laptop. Plugged it into my desktop booted it all up with various different attempts eg.

 

x32 -v

-v

-x

arch=i38x (something like that can't remember)

 

Whenever it goes to boot too the white loading screen it Kernel panicks with:

 

System uptime in nanoseconds: 186... some other numbers to follow.

 

I'd REALLY apreciate some help, being trying to get this up and running for hours now, I did previously a few months ago (before I went back to win7) have 10.5.6 running via iaktos and it was required to patch my bios if that's relevant. Only really interested in getting SL running now due to all the updates not being released for 10.5 anymore.

 

Well cheers, hopefully someone can help me.

PC EFI 10.1 this is very old try this This Chameleon and its latest greatest AKA PC EFI 10.xxx

 

And if you already can get OS X (10.5.7) running its very very easy to configure an install off an already running one.... Simply install and prep your USB pen drive for SL 10.6.x with Chameleon its very simple tonymac USB PEN drive

 

Try [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] also should get you booted with your HD4870

 

-x so you can get the correct kext's installed for your HD4870 or you will either get a garbled screen that you can't do nothing on or you will KPanic

 

Make sure you have items below if your going to boot off your HDD. Green check. Extensions.mkext is created using Kext Utility ITS located here under TOOLS and so are a lot of great kexts

Thanks very much for your help, really appreciated.

 

I'm going to re-install a fresh copy of the snow leopard DVD onto the hard drive, and then from scratch install just the updated chameleon loader you sent me a link to.

 

Then work on it from there and see what happens. If anyone else has got a maximus formula II board working I would really appreciate the help! :D

 

EDIT - FIRST ATTEMPT

 

Well I re-installed SL to my external HD, booted it up using macbook laptop. From there I uploaded the DSDT.aml in the tutorial too the root, installed the new chameleon boot loader you linked me too. Didn't paste any of the extra kexts suppled though.

 

I then edited the boot.plist so that it's GraphicEnabler=yes.

 

From there plugged the hard drive into my desktop PC, booted up and loaded the chameleon boot loader, I then tried to boot with -x32 -v -x and just -v, both kernal panicked with the following errors:

 

-x32 -v -x... KP = IOAPIC: Version 0x20 Vectors 64:87

 

-v... KP = Using PCI-Root-UID Value: 0

 

Don't know how to get around these errors, I currently have no extra kexts installed like I previously did on the last install. If I can't get it fixed soon I might just install 10.5.7.

arch=i386 in your com.apple.Boot.plist ... make sure it spelled exactly like "com.apple.Boot.plist". Yes, with the capital "B" its case sensitive. In the pic its not spelled correctly for some reason, forget why.

 

 

<key>Default Partition</key>

<string>hd(0,2)</string>

<key>EthernetBuiltIn</key>

<string>Yes</string>

<key>Graphics Mode</key>

<string>1920x1080x32</string>

<key>GraphicsEnabler</key>

<string>Yes</string>

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string>arch=i386 cpu=1 -x -v</string>

<key>Timeout</key>

<string>2</string>

 

What kext's are in your Extra/Extensions folder?
