NOTE:
With the new Pentium III processor, it is not necessary to set jumper
switches to determine the bus processor frequency. The Pentium III processor is self-
adjusting.
Two-pin jumpers are described as jumped, “on” or “in” with the small plastic jumper
cap on, or not jumped, “off” or “out” with the jumper cap off.
Jumpers with more than two pins are described by numbering the pins. Each of the
SBP-205 jumpers has the number “1” stamped on the board next to that jumper’s pin
number one.
The jumper cap placed over a particular combination of pins, such as 1-2 or 2-3,
determines the jumper setting.
