IWill x X7460

Noticed that this is an old community, so I thought you could have what I need.

I bought a kit w/ one IWill DNS-SATA and six Xeon X7460, but I'm not sure if they're compatible. The shop from which I bought said they wered used together on a working server machine, even with the not fully compatibility between the Xeon X7460 (2008) and IWill DNS-SATA (Intel E7520 Chipset - 2004). Is it even possible? And, do you know where to obtain the latest BIOS for this motherboard?

Well as you can see, it appears this was asked on the intel site and they are "not compatible" as stated by the intel person.
