That drive sports a firewire connection and, as long as your motherboard supports it, is DOS-bootable, so in theory your BIOS should recognise the drive and allow you to boot from it.
I have checked the drives specification and it is compatible with your laptop, so my only guess is either an incorrect BIOS revision or a faulty cable/controller somewhere along the line.
Does the drive spin up or give any indication that it is actually on? If so, does the read light flash when you insert a disc? If possible, pay close attention to the POST and following screens to see what drives are listed - you may need to press and hold a key to see this information as many newer machines hide this information and instead show users a more "friendly" screen.
If you can provide a little more information I may be able to help narrow it down a little.
