Not properly tested yet, but I bought a DDW-082 w/B370. I have a P4 VIA P4PB ultra mobo(looking to replace it). When I flashed it the 082 was the only CD drive connected(secondary master,cs[computer select] but jumpered to "master" if I had to do it again), also a sony 3.5 floppy and a memory card/stick drive and a Maxtor 120G 7200rpm.
I downloaded a zipped file. I unzipped the file by right clicking on it and chose the proper utility. After double-clicking the B373 flash ran itself, a lot like loading a device driver. Quick and easy.
Everybody recommends closing all running programs and shutting off virus programs and turning off your internet firewall which should also be done with any other update(and don't touch anything wihle it's running). I read a post that recommended using windows 98 because xp could be a problem. - I am using xp pro + had no problem.
I reloaded windows a few days later(forgot to turn-on firewall) and the drive caused me some problems reading files on the first attempt, but worked on the second. Have had little problems since. Have played DVDs but not yet burned. My P4PB seems unhappy running 2 CD drives but does it.
If they are like me, other people will read this post.
