I'm thinking...............
1. Perhaps the new mobo is faulty as far as this peripheral is concerned
2. Have you accidentally bent a pin on the mobo socket where this device plugs in?
3. Does the mobo have a jumper wrongly set to enable this device? (Compare to old mobo)
4. Is there a separate power connector for this device which you forgot to connect? (Probably not if it's whirring)
Can you connect this optical to another system temporarily just to check that it's working?
If the system BIOS can't see it then you have no hope until it does.
