1. JUMPERS
A jumper is two, three or more pins which may or may not be covered by a plastic
connector plug (mini-jumper). A jumper is used to select different system options.
Please make sure all jumpers at correct position before this system board used.
(A) JP1 CPU operating voltage selection
Different Pentium Pro processors may require different operating voltages (VccP).
Current processors (marked "Pentium Pro") support VID and will automatically
adjust the output of voltage regulator so that no jumper setting are needed (leave
these jumpers open in this case). Some
older processors without VID support
require manual voltage ID setting. The following table is used for those older
processors only.
