Clock Speed Setup Procedure; Table 2-6: Cpu Bus Clock Setting (Jp19); Table 2-7: Cpu Select Jumper Settings(Jp14) For Intel And Cyrix Cpus; Table 2-8: Cpu Select Jumper Settings(Jp14) For Amd Cpus - Advantech POS-560-B1 User Manual

Clock speed setup procedure

a. Check your CPU speed and type (ex. Intel P-133)
b. From the above CPU speed relationship chart, find your CPU's
corresponding clock speed and frequency ratio setting (ex. 133
MHz = 66 MHz x 2)
c. Set your CPU's clock setting on (JP19).

* default setting
d. Set CPU's frequency ratio (JP14). Consult your CPU's manu-
facturer for further information when making your selection.

e. Finally, set the SiS 5571 DLL optimizing timing adjust (JP22)
based on your CPU's bus clock speed setting in Step c.
