2.4 – CPU Front Side Bus Jumpers (J48, J49, J52, J53)
NOTE:
YOU MUST SET THESE JUMPERS AT THE SAME SPEED TO EACH OTHER IN
ORDER TO PROPERLY OPERATE THE TIGER MPX. THIS IS REGARDLESS OF WHETHER
THERE IS ONE OR TWO PROCESSORS INSTALLED.
TYAN will not be liable should damage be caused by not properly setting these jumpers, or any other jumpers.
TYAN will not take responsibility if improper and incompatible processors are used on this board. Please refer to
our website for the lat est processor compatibility charts. You may also refer to the specifications page for the
Tiger MPX in this manual.
266MHz
200MHz
J52
2-3
1-2
Connect pins 2/3 on J52, and 2/3 on J53 to set the FSB speed to
266MHz.
J53
2-3
2-3
Connect pins 1/2 on J52, and 2/3 on J53 to set the FSB speed to
200MHz.
266MHz
200MHz
J48
1-2
2-3
Connect pins 1/2 on J48, and 1/2 on J49 to set the FSB speed to
266MHz.
J49
1-2
2-3
Connect pins 2/3 on J48, and 2/3 on J49 to set the FSB speed to
200MHz.
TIP:
Setting both jumpers to operate at 266MHz will ensure safe and proper operation regardless
of whether the processor(s) installed operate at 200MHz or 266MHz.
2.5 – Force 33MHz PCI Bus (J93)
1
2
On: Force PCI to operate at 33MHz
Off (default): PCI operates at 66MHz
2.6 – Disable/Enable LAN (J86) – (Optional Feature)
1
2
Closed (default):
LAN port is disabled.
Open:
LAN port is enabled.
TIP:
Set the LAN port on or off before installing expansion cards so that they don’t get in the way
of the jumper. Also, the 3C905C 3COM Ethernet controller is a high quality, high efficiency
solution. TYAN recommends using the 3COM controller instead of installing a separate Ethernet
card.

Use this connector to attach a rear panel or front chassis USB ports. Front
chassis USB ports are dependant on the chassis used and the
manufacturer that makes them. Check your chassis manufacturer’s website
for models that include front USB ports.
TIP:
For convenience, look for a compatible chassis that also includes USB connectors. This will
provide a convenience if you should ever need to connect devices like digital cameras or other
USB devices.

This connector is reserved for diagnostics functions usually used by system
integrators and OEMs (Original Equipments (or Electronics) Manufacturer).
