i can make a guide but Snow is not publicly released yet plus still waiting for a better audio kext on 64bit other than voodoo.. im using stock applehda now + legacyhda (e/e) but i have no audio feedback if i change the volume, the rest are fine though..

not an expert too so maybe we should just let the old timers guide us here and we should just follow

It would be awesome if you would. Even though the GM may not in fact be final, the same steps would most likely apply, no?

Anyway, I just tried installing again with the kexts you specified (minus voodoo) and this time it wouldn't even boot past the Apple logo. Just keeps spinning.

dsmos
nullcpu
openhaltrestart
platformuuid
decrypt

All 64-bit versions as far as I know. Not sure what I'm doing wrong :/

Didn't patch DSDT for CMOS fix, haven't yet figured out how but it should still boot without it from what I've read.

i made one here, tested it a few times and it works perfect

full 64bit plus /s/l/e untouched..

I Think Ive found the solution for sleep on 10.5.7+ You need to disable Paragon NTFS.

Anyone willing to help? I posted a video on youtube displaying what I am encountering.

G31M-ES2L Motherboard
Intel Pentium D Chip (also tried P4 630)
2GB DDR2 800MHz Memory
IDE Hard Drive & DVD Drive on same cable (hdd is master, dvd is slave)
nVidia Quadro FX Graphics (PCI Express)

I boot from Boot 132 and insert retail 10.5.6 (back up copy, burned with transmac on a PC) and then the PC reboots. Tried -v flag without luck,

I have done a lot of reading, but there is a great chance my mind is garbled from all the different places I have been getting my info.

Here is the video: http://www.youtube.com/watch?v=yqW-EbrhUxU

I havent got this board yet but the dsdt.aml you attached will i be able to use that on my machine, or will it need re compiling?

Thank you for this guide, very nice.

The uploaded files and the efi partition mounter made it very painless.

I used it to update the drive I pulled from my d945gclf2 for this new board.
The only issue I ran into was no sound, but then my 10.5.6 install probably had some baggage. I solved it by removing HDAEnabler from EFI partition and S/L/E. By just using AppleAzaliaAudio.kext and AppleHDA.kext in S/L/E it gives me headphone sound from back connector, it appears as "HD Audio Output" device in sound preferences.

I like this board so far, my graphic card hasn't arrived yet, but with the onboard video I'm only using 35 W (at the wall outlet) while writing this and I peaked 70w when really pushing the cpu so I'm hoping my picopsu will be up for the job.
(I'm into the low noise, low heat aspect mostly)
Next step SL :-)

G31m ES2l
E6300 2.80 GHz SLGU9
Samsung HD502HI 500GB (1 platter ecogreen)
PicoPsu 120wi

edit:

Installing the graphic card (7300gt 256mb) and higher res added about 15w to idle, oh well...

I was going to post a bunch of crap, but i'll save it for a thread elsewhere.

The bottom line question, has anyone worked with Rev. 2 of this board? I'm about to buy all of my hardware. I am left to assume I will most likely receive rev2 which has the AR8131 LAN. I don't want to buy a different NIC to make ethernet work, or I'd rather just buy a different motherboard.

Anyone know if there is a workable driver for this new chip? Thanks.

I got "Invalid Argument" error when I tried to execute the EFI-Partition-Mounter script ... help ... seems that I'm missing something in mount_hfs command line but not sure what ... tkx!

For all of you using the Gigabyte GA-G31M-ES2L, I have been running this board for awhile. Attached is legacy audio for Leopard and Snow Leopard and some tools. In the zip is a folder called HDA, in that folder is 2 other folders, one for Leopard and one for Snow Leopard and 1 file dsdt.aml. You can use either the dsdt.aml or the HDAEnabler.kext (don't use both) along with the HDA.kext. I use the dsdt.aml for my sound which just injects audio information (layout-id, and pin configurations) and the HDA.kexts injects the proper layout information for your on-board audio to work. HDAEnabler.kext does the same thing as dsdt.aml, it just injects it in a different place in the IORegistry. put the dsdt.aml file in /Extra and the HDA.kext and HDAEnabler.kext (only if you don't want to use my dsdt.aml file) in /Extra/Extensions. rebuild the /Extra/Extensions.mkext using MKextTool and reboot if your using leopard. if your using Snow Leopard, follow the above directions except run Kext Utility app in the tools folder instead of MKextTool and then reboot. You should now have line out, front headphones, line in and mic working. Don't forget to remove all of your other sound kexts (AppleAzailia, Voodoo etc. before you run Kext Utility).
