If you do not know how to handle BIOS setup or how to set it up properly, it is strongly
advisable that you do not modify any of the settings than otherwise instructed in the User’s
Quick Start Card. Even a seemingly small incorrect adjustment or modification in the BIOS
setup can render your system unstable or unusable. The incorrect BIOS setup is not covered
by your motherboard’s manufacturer warranty.
