ND6500 not recognised

Following a system crash, my system now won’t recognise my DVD drive (NEC6500). The crash happened as I was turning my laptop off. Evertime when I boot up now, I get a black screen asking whether I want to start Windows or Crash Recovery Console. I’ve checked the BIOS and the DVD drive is not appearing as secondary master drive, although it used to be. In fact it’s not registering at all. My Computer within Windows doesn’t detect any drive now and I cannot seem to retrieve it. The BIOS is Insyde Software’s MObilePRO and it doesn’t have any drive detect option. Could it have anything to do with the firmware?

Please can anybody help?
