Okay. Drives are installed, and on my nForce4 Ultra SATA controller. My Mainboard BIOS identifies them properly. Firmware is listed as 1.09. Nero 22.214.171.124 recognizes them fine. Wrote a full dvd with my current Verbatim media (MCC 03RG20) at 8x, (V for Vendetta, if anyone wanted to know), which plays back fine on the same drive and scans just fine with Nero CD/DVD Speed. I really only bought two so I could go entirely SATA, I normally have one playback ROM drive and one writer, but they both seem to work fine.
I don't have a lot of fancy testing equipment, but at least I can say you don't need an Intel chipset for them to work properly. I haven't tried booting off them yet but I have no reason to think that they won't.
