The motherboard page is here (http://support.intel.com/support/motherboards/desktop/SE440BX2/), but it seems that no bios update increases the size of disk supported. In this case the limit is 137GB (see here (http://support.intel.com/support/motherboards/desktop/sb/CS-009028.htm)).

Looks like you've already been pointed at the utility you need by xraycb, although if you choose the PCI add-in controller suggested by emarkienna you will get the best performance.
