How do I find out what DVD Drive is in this machine without opening it up? And how do I upgrade the firmware?


If you’re using Windows, open the system/hardware tab/device manager.

Go to the manufacturer’s website and see what the latest version is. Check CDF or TDB if there are any crossflash possibilities (increase capabilities of your burner but will void your warranty).

CD Speed will also give you drive information.



This for the 1105GHC+ DVR.
