Chipset Features Setup Menu
The Chipset Features Setup Menu is used to modify the contents of the buffers
in the chipset on the mainboard. Since the parameters of the buffers are closely
related to hardware, if the setup is not correct or false, the mainboard will become
unstable or you will not be able to boot up. If you don
’
t know the hardware very well,
use default values (use the LOAD SETUP DEFAULTS option).
