You are mixing up multiple installation methods, therefore chaos will ensue.

I have a Release 1 board and a Release 2 board. Both work with the guide at the front of this thread. The guide at the front doesn't talk about iBoot or Multiboot, so don't use them here. Start at the beginning and work through the first post in this thread. It does work as I have done it on a number of occasions.

If you want any help, start at the first post, download the various files in the links and work your way through each step in order. if you find yourself stuck on a particular step, then ask for help. But do follow the steps in the first post. You do not need to look at any other post to get the OS installed.

Things you need to know:

1. State exactly what you have done to get it working based on the steps in the first post. Do not mix kexts up from other installation methods and hope it will work, it may but then again it may not and nobody has any idea what state your install is now in. I repeat the install instructions do work for both revisions of the G31M-ESL board. The more information you give, the more chance of somebody helping you. Whining doesn't help.

2. Ignore peripheral issues like sound and graphics, get a base install working first. You say you have the R2 release board therefore you will NOT get ethernet working on the MB, disable it in the bios and get a supported ethernet card. I have ethernet cards that work in the PCI slot and the PCI-E slot. The Ethernet cards are cheap $5-$15 range. You're saving hundreds of dollars on a mac, get a supported ethernet card and don't try to get some obscure manufacturer to work.

2. Sleep is a major pain and I have never got it to work. I remove the sleepenabler.kext and you will need to remove it to get the updates to work. Do not do updates until you have a stable system, if it's not stable for 10.6.0 it will NOT be stable at 10.6.4.

3. Sound can be a pain on both R1 and R2 boards, I use an external USB sound card, the iMic to get around this problem.

So go to step 1 on the first post, download the files and work your way through it line by line. When you don't understand ask, but as many people will state, the instructions do work.
