Hey all, followed the directions and installed Snow Leopard on my G31M-S2L (not the G31M-ES2l); had initial problems because I have an ATI-4850 and the boot loader doesn't support the graphics chip, so I had to install with the -x fix. Someone should ask them to include the new boot file from netkas.org which supports more recent graphics cards.

Nevertheless, got it installed, and got graphics working with ATI4800Controller.kext (after making changes to ATI4800Controller.kext). Installed 10.6.3 -- reinstalled the new sleep enabler, graphics didn't work again so I had to revert to drivers from 10.6.2. I have a external sound card via USB (creative X-MON) so everything works fine.

I was a bit confused with the DSDT file because the changes mentioned couldn't be found in my personalised dsdt file. I moved it to /Extras anyway.

Now, my only problem, my SL hard drive sometimes randomly just reads and I can't do anything on my computer. For example, I'll be surfing with google chrome with minimal apps open, and the red light on my computer will blink for a minute or so. In that time period I can't do anything. I'm using a SATA hard drive, with S.M.A.R.T turned on, partition map type is MBR shared with a Windows 7 partition.

Has anyone experienced this? I've run iDefrag, but I still have the problem. I have 4 GB of physical ram which I think is sufficient to run SL. I'd appreciate any help!
