I got the same board with an E8400, 2GB with the F6 bios and did a clean install with Chamelion RC4 and the retail dvd. Everything works, even the onboard graphics in 64-bit mode except for sound. (only1024 though). Got an ATI HD4650 available that i can try, but i am not sure if i can install this card after the install of OS 10.6. Any hope? I also got a G41M-ES2L board. Is this a better board for running Snow? Could anyone point me to any guides with regards to dsdt etc. I have no clue what this is or what i should do to after the install process so that i can f.ex boot from the HD.
