Problem flashing nec7900A in Dell

I have been totally unable to flash my cdrw drive from Dell and wonder if I would also have problems flashing another drive. I have ordered the Liteon DVD-RW 411s and it needs a flash to work properly. If my Dell won’t flash one drive, I am afraid it would also have problems with a different drive. Should I be worried. Do you think I could flash the drive by moving it to another computer, then back to this one?
