Hello and sorry for bothering you with what probably is a pretty easy question but I need to flash my NEC ND-4551A drive so I can burn DVD+R DL cd's, I've downloaded the firmware which is in .bin format but I have no clue how to apply it, I've googled for hours trying to find a flash utility etc but I can't find anything compatible with Windows XP.
Would be greatly appreciated if anyone could help me out!
(please keep the explanations somewhat simple since my computer skills are not too vast)

Thanks!
