Firmware for LG DVD ROM GDR-8161B

Hi I just reinstalled XP on my sisters computer It has a CD burner and a LG DVD ROM Model GDR-8161B The DVD ROM doesn’t see a disk in the drive it always asks “Please insert a disk into drive” I kept and image of the original installation and reimaged it back with Acronis True image (like Ghost) and the same problem so I am guessing it is a problem with the firmware (My sister probably never used that drive and only used the CD burner on the rare occasion she used an optical drive)

If you agree with my diagnosis can you point me to where I can find some firmware that will work off windows desktop (XP) I haven’t been able to find any only dos related so I would have to find a Win 98 box.

Thanks in advance for any comments.
