Help with firmware upgrade nec 3500ag

Hi, I’m very new to this and I really don’t know what I’m doing, any help is appreciated.

I have: NEC DVD_RW ND-3500AG 2.98

exactly which is the latest firmware ugrade for this, because there are one too many and it’s confusing, I can’t tell which is the latest. Also, is there a step by step safe guide on how to do this procedure? I’m clueless and ignorant in this matter. I’m afraid I’m going to ruin my machine. Thanks

If you read the the table provided by Dee there are four category for firmware to be upgraded, first you have to know your own need, then decide which category suit you the best and choose that one for upgrading your drive.
