I just bought the 4163B yesterday. How do I find what kind of firmware I am using? Is it worthy to upgrade the firmware? Does 4163 has bitsetting?
If you just bought it, read the sticker. Surely there’s a more recent firmware version out there already.
If you haven’t installed it, it’s on the drive label, otherwise use a program like Nero Infotool or DVDInfo Pro to find out the firmware version. You could also run the firmware update program (without actually updating the fw), it should also tell you th version.
Also the 4163B does support bitsetting for +R and +R DL media, but not +RW.
