Don't be flashing your DVD!
So many people here leap directly to "Flash this", "Update that"... when in all likelyhood it's nothing but a settings problem... Really... Flashing stuff is like the absolute last resort before it goes in the garbage can!
Ok it's an IDE drive... Is it master or slave?
Some IDE controllers won't list a slave if there's no master present...
Is the IDE controller enabled in your BIOS?
Are all cables and power leads connected and sound?
Hint: IDE cables are frail things, you can't tug on them, not even a little bit. Most are good for 2 or perhaps 3 disconnects before you're ripping wires out of the pinch connectors.
MadMaxData is on the right track ... and rather than heading off in 50 different directions I would strongly suggest you follow his guidance on this one...
