CPU Type Configuration
SW1 and JP30 are the only switchs/jumpers that you need to set for your
CPU on this mainboard. Make sure that you know the type of CPU that
you are installing and refer to the proper settings which are listed below.
If you have a higher frequency CPU then the one listed below, see the
ÒQuick Installation GuideÓ for more SW1 information.
SW1:
Frequency Setting
. Some newer CPUs may not be included in
this section, please refer to the Appendix for more information.
JP30:
Voltage Setting.
There are two kinds of CPU voltages
currently on the marketÑSingle and Dual. The CPUs which
fall under the single voltage category are: P54C, AMD-K5, and
Cyrix 6x86. The CPUs which fall under the dual voltage
category are: P55C, AMD-K6, and Cyrix 6x86L/MX. This
board is designed to detect the CPU voltage automatically for
P54C and P55C CPUs due to the Smart Detect CPU Voltage
function, and therefore, there is no need to move any jumpers to
set the voltage for P54C/P55C CPUs.
