I just installed them (didn't uninstall anything first) on my Maxtor Diamond Max 200GB drives last night, set up in a stripe array. I did not install the nVidia IDE driver or the network drivers. NCQ was still disabled after install. Enabled it through device manager, have had no issues so far. Still running with 1002 BIOS, since I had the disappearing drives with other versions.
Have had no sound issues, but haven't really checked that yet. I did notice I got a new nVidia mixer. I'll make sure my sound is ok later. I also have a Plextor 716A burner, which someone reported they ahd troubles with. Haven't burnt anything with it yet, I'll have to give it a try.
