Explanation of
Jumpers
To modify the operation of the
motherboard, jumpers can be used
to choose between optional set-
tings. Jumpers create shorts be-
t w e e n t w o p i n s t o c h a n g e t h e
function of the connector. Pin 1 is
identified with a square solder pad
on the printed circuit board. See
the motherboard layout pages for
jumper locations.
Note: Closed refers to the jumper being set
over both pins on a two-pin jumper header.
Open refers to the jumper being set over a
single pin of a two-pin jumper.

* Note: The Auto setting allows
the CPU to set the speed.
Front Side Bus Speed
JP1 sets the FSB speed. CPU
speed = FSB x Core/Bus ratio.
Core/Bus Ratio settings are de-
scribed in Section 5-8. See Table
5-18 for jumper settings. Chang-
ing the setting of this jumper must
coincide with changing JP63 (be-
low).

Chipset Speed Setting
JP63 sets the chipset speed and
is used in conjunction with JP1.
This setting lets the chipset know
what the FSB speed is, and so
JP1 should not be set to Auto. The
setting of JP1 and JP63 must be
equal (both set to 133 MHz or both
set to 100 MHz). See Table 5-19
for jumper settings.
