1. Setting Jumpers
1-A. CPU Speed Settings (Jumpers JP10, JP11, JP12, JP13)
There are two steps to set the CPU speed. First, set the
clock multiplier
with
jumpers JP10 -13 according to the specification of your CPU using the chart
below. After the system is ready to boot up you will need to set the
bus speed
in the BIOS setup. This is covered in detail in Chapter 3 of this manual.
Presently all Celeron CPUs use a 66MHz bus speed. (Tyan does not recom-
mend operating CPUs, memory, or PCI Bus at higher than rated speed. Tyan
takes no responsibility for any problems related to overclocking any bus or
component on the system board.)

* The VIA chipset versions bus speed is Auto-Determined by the CPU. The BX
version can support 133Mhz by overclocking
the chipset but it is not recommended by
Intel
TM
and Tyan.
Currently S1857 does not support some
older Slot 1, 66Mhz bus Pentium IIs
that use a 2.8 core voltage. Please refer
to the link on page 26 for the most
updated information on CPU support
for the Trinity 371.
