Microprocessor Configuration (J4L2)
These allow the system board to be switched between different speeds of the Pentium Pro
processor. These jumpers also affect the PCI and ISA clock speeds as shown in Table C-
72.

Motherboard Configuration (J4L2, J1J1)
The jumpers for sections D, E, F, G, and H of J4L2 allow the selection of various system
board features. A second jumper block (J1J1) allows selection of a riser board with either two
or three PCI board connectors. Table C-73 lists the system board configuration jumper
positions and indicates the meaning for each position.
