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.)
