Recently, many viruses have been found that they may destroy bios code and data area. Therefore, this motherboard implements a very
effective hardware protection method that does not involve any software or BIOS coding, hence it is 100% virus free. You may restore the
originally mounted BIOS with 2
nd
BIOS ROM by setting JP30 to pin 2-3 if it fails to act normally. This motherboard comes with one BIOS
ROM, you may contact our local distributor or reseller for purchasing the extra BIOS ROM. Please visit our website:
