(E) SW: FSB Clock Selection
SW is designed on the board to choose the CPU FSB clock (Front Side Bus
Clock) for some special purpose. Basically, you don't have to worry about the
FSB clock because it will be detected by the mainboard automatically. When you
have installed the CPU onto the mainboard, this mainboard will detect the CPU
type and specify the proper FSB clock for the CPU. So you need not to make any
setting to select the FSB clock. However, sometimes you may feel like to select
different FSB clock for some special purpose. In this case, you may use the BIOS
setting to select different FSB clock or use the switch setting on SW to force your
CPU to use the selected FSB clock.
(Please do not attempt to change this setting
unless you are the technician)
