Thanks for this instructions.
I am going to try it this week.
But as I never endeavor something like this before I have one question.
Does it work with any network card?
Is there a kind of generic driver that will be used?

Regards

a lot of network card its native suport!
rtl81xx,, gigabythe AppleRTL8169Ethernet.kext,AtherosL1cEthernet.kext, ,,AppleIntelE1000e.kext

you just need to install one of this driver

and for the wifi card its litlebit different but its same

post a good picture of the screen on boot; use this boot flag-v

when the usb key satrt type space keyboard and type the boot flag, after hit enter


and try this boot flag to one by one
respecte the space
-f -v PCIRootUID=1 npci=0x3000 GraphicsEnabler=yes
-f -v cpus=1 USBBusFix=Yes npci=0x2000
-f -v PCIRootUID=1 npci=0x3000 GraphicsEnabler=no
-f -v -x GraphicsEnabler=No cpus=1 npci=0x2000
-f -v -x GraphicsEnabler=yes cpus=1 npci=0x2000

I tried every one of them and the error is the same:
This photo is the first phase with graphicsenabler=no => http://s17.postimage.org/hwiezlsxq/IMG_2618.jpg
With graphicsenabler it shows that it recognizes 580gtx
The first page of the second phase is the same in everyone => http://s17.postimage.org/9pqf812v2/IMG_2617.jpg
And the error that it shows me and everyone too is => http://s17.postimage.org/3m8uo4cla/IMG_2614.jpg
and after that it shows => http://s17.postimage.org/okf0m7cfy/IMG_2615.jpg
and right after that the computer restarts

And i changed the BIOS configuration to AHCI, anything else i should change? because i saw people change HPET and i couldnt find it on my BIOS page
