(D) SW2: CPU Clock Ratio Selection
(optional choice)
SW2 is designed on the mainboard to select the CPU clock ratio. Basically, the
CPU clock ratio will be decided by the CPU automatically. When you have
installed the CPU onto the mainboard, the CPU clock ratio is decided
automatically and you can not use the switch setting on SW2 to change the clock
ratio. In case that your CPU allows you to change its the clock ratio, then you may
use SW2 to select the clock ratio.
