I just got a i/o magic, benq 1620 oem burner. It shows up as a atapi 16x16x. I am running windows xp. Could some one give me a step by step procedure for upgrading the firmware to a retail benq 1620? The burner is now firmware g7c9. I have searched the forum ,but I getting confused as to do it properly. I would appreciate any help on this ,thanks.
