Many viruses have been found that they may destroy bios code and data area lately. This motherboard implements a very
effective hardware protection method without any software or BIOS coding involved, therefore it is 100% virus free. You may
restore the originally mounted BIOS with 2
nd
BIOS ROM by setting JP24 to pin 2-3 if it fails to work properly. This motherboard
comes with one BIOS ROM, you may contact our local distributors or resellers for purchasing an extra BIOS ROM. Please visit
our website at www.aopen.com for details.
