Hardware Installation
CPU AJ33 and AJ31 Settings: JP6, JP7, CJ1 and
Step 2.
CJ2
For certain Intel CPUs, the multiplier is not locked such that setting a
multiplier higher than specified on the CPU is possible. For technical
details read the following:
Your PII /III 100/66 MHz FSB CPU has a pin AJ33 (100/66# signal) to
tell it what FSB frequency the CPU requires; The PIII 133 MHz FSB CPU
has two pins AJ33and AJ31 (133/100# signal). JP6 and JP7 are connected
to the AJ33 and AJ31 input respectively and are used to tell the
motherboard what the CPU FSB frequency is. If these two jumpers are
shorted the motherboard will automatically run at the frequency the CPU
was specified to run at.
However, the FSB Frequency can also be set through jumpers CJ1 and CJ2
and it may therefore differ from the Frequency the CPU specifies. If CJ1
and CJ2 are to be used, JP6 & JP7 must be open. Doing so may however
force your CPU to operate out of its specifications and therefore SOYO
can not guarantee the proper functioning of your system.
