Does the same apply to the 3132? The motherboard in your sig uses a 3112/3114, a PCI model, but the 3132 is a newer and is on PCI-E. Silicon Image offers official OS X drivers for the newer 3132 based PCI-E cards, but didn't for the older 3112/3114 models.

I can't find a single account of someone running a burner off a 3132 based card but figured it would work because of how widely recommended that chip is for OS X.

Also, I have read in several places that nforce4 SATA burning doesn't work, but those accounts were from a few months ago. I don't think it should work. Are you running an SATA burner on your nforce4 SATA ports?

I will probably avoid the headache and just get an IDE model, the only issue is cable clutter affecting airflow, and not being able to reuse the drive in a newer system. Annoying, but not a dealbreaker.
