HP dvd writer question

[TB582]

I have a HP DVDwriter300 and I found the firmware to upgrade it to region free from http://etna.rpc1.org/nec/index.html I am just a little unclear on what RPC2 Original, RPC2 ( autoreset) and RPC1 are, what are there functions? which one should i download? I'am assuming the RPC1? also the directions on how exactly to flash the drive are a little unclear, I was wondering if any one could clarefy them for me. Again I just want to make my dvd burner region free and i'm not sure which one to dl.
