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
