Chapter 2
Board Installation
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 the BUS Speed is auto-detected.
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.)
JP10, JP11,
JP12, JP13
