    The SP-45 is an ASIA bios rom, where as SP-1 is a Japan bios rom.

    There should not be any difference when installing the neobiosmasta.

    As for lifting the legs, I apply some flux to the legs, then using some tweezers I grab the leg and lightly pull up while heating the base of the leg with a soldering iron.

    Did you end up getting the legs lifted? If you don't care at all about the stock bios and you don't have the means of lifting a leg, you can cut the legs and remove the chip. Then just desolder the remaining legs. I don't like to do this personally but most people would never go back to the surface mount bios even if they decided to get rid of the board.
