Hi I am very Fimilair and have flashed many drives latley so quick start you need to find out which DVD drive u have and then order a SATA CARD to hook the drive up for the flashing search VIA sata Card in ebay (has to be a VIA sata card)

Personal Opionion on flashing-Take's a bit to get the right hardware and all tutorial's made but after that its very easy and worth flashing. (flashing takes like 5minz no more once setup)
