Note: In most case, you don't have to use the switch setting to
select the CPU clock ratio because it can be detaected by
the mainboard automatically. The Celeron
™
processor,
Pentium
™
II and Pentium
™
III processors do not allow
you to change the clock ratio, so the setting on the toggle
switch will be invalid..
