Under no circumstances try to install a BIOS for a different motherboard. If you are lucky it will just refuse to install, if you are not, it could render the motherboard useless. Only ever attempt to install official BIOS updates specific to the motherboard. You can try modified BIOS updates, specific to your motherboard, at your own risk.
Best policy is to only update the BIOS if it actually necessary to make your PC work properly.
