I had firmware version 0C09 in hp/compaq nx7010 with +-DVDR and +-DVDRW supported. Then I updated drive with Sony 0S35 GMA RPC1 firmware from The Dangerous Brothers. http://forum.rpc1.org/dl_file.php?site=tdb1&file=4080NS35.ZIP
Now my drive is GMA-4080N and also supports +DL and DVDRAM.
Thanks TDB very cool
what program/utility do you use to load the firmware? I downloaded the file you referenced but it doesn't recognize my drive.
