CPU Installation
The 586STC allows for easy installation of CPUs. Make sure all jumpers are
set correctly before applying power or you may damage the CPU or system
board. Use a needle-nosed plier to move the jumpers if necessary.
Jumpers JP1, JP10, JP11, JP12 and JP13 are used to set the external bus
clock of your processor. Refer to the following pages for the external bus
clock that corresponds to your processor and set these jumpers accordingly.
The clock generator will determine the external bus clock that must be sent
to the processor through these settings.
Jumpers JP6 and JP7 are used to set the frequency ratio of your processor.
Refer to the following pages for the frequency ratio that corresponds to your
processor and set these jumpers accordingly.

If, for some reason, the CMOS becomes corrupted, the system can be
reconfigured with the default values stored in the ROM BIOS. To load
the default values, power off your system and set JP9 pins 2 and 3 to
On. Power on your system. After you boot up an operating system, turn
your system off again. Set JP9 back to its default setting, pins 1 and 2
On.
