Ah, that's the missing information I needed. You have the old ME firmware and it won't allow itself to be updated. In order to get the later BIOSs and later ME firmware installing, you need to do a BIOS recovery operation. The instructions for doing this can be found here: http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm?wapkw=bios+recovery...
