NEC 3520A - Which Firmware?

I just bought an OEM NEC 3520 and would like to know which firmware (if any) I should use? Please let me know the best (if any). I would like to do bitsetting with DVD + R’s, otherwise I will just use DVD - R’s. By the way, I am a complete newbie so could you please let me know where to get and how to use the firmware ( in fact I am not even sure what firmware actualy is ), do I just install it and that is all?

ps- will my warranty be void if I update to the latest firmware?

Time to read the NEC FAQ :slight_smile:
