DG41rq, I've just got this working pretty well with a pcix video card. I'm running 10.6.4 using the tonymac multibeast. I used a acl662.kext and one of the voodoo hda's. I found them both on insanelymac.com I think. (It was very late) If you use the multibeast make sure to select the realtec networking instead of intel networking. I still cant get my core 2 duo recognized properly. It thinks it is a core 2 solo. I wish I could get the mobo to make the mac sound on boot. I keep looking at the different intel mobo utilities. Maybe after I get a time machine disk. Good luck CFI
