Intel Core 2 Quad in IBM 8104 w/ Mobo 39J6410?

Hi I've ordered an Intel Core 2 Quad as an upgrade for this computer. The mobo is the same socket (LGA 775) but I'm not sure if it will work with the BIOS and such. Firstly, does it work and secondly, what should I do if it doesn't?

According to IBM, a Core 2 Quad will not work. Here is a list of supported processors: http://support.lenovo.com/...s/pd012099
There's nothing you can do to make it fit. Hopefully, you can get a refund.

You shouldn't have any problems. If you do, most companies have a return policy (or you could replace your motherboard for about 100$-150$).
