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: www.aopen.com
for details.
