Hey Hey,

I'm running out the door but I'll throw up a quick response.. Check for BIOS updates... Check that your BIOS supports the 128GB Limit.. you may need a controller card added to your system... Check and see if your motherboard supports the 48bit addressing.

If you haven't seen this link, you can check it out here.
