JP3, 4: Bus Clock Selection
- This jumper set is explained in detail on page 9.
JP5: CPU Clock Ratio Selection
- This jumper set is explained in detail on page 9.
J13: CPU cooling fan connector
- Hook the CPU cooling fan power connector to this
jumper, observing the correct polarity. Pin-2 corresponds to the RED power
lead as shown:
J16: IDE Activity LED
- Hook the IDE LED lead to this jumper, with the
RED lead corresponding to Pin-1.
J15: System Functions Jumper Block
Pins [3 & 5] Turbo LED switch
- The Turbo function is
not supported by this mainboard. Therefore, the Turbo LED
will always remain lit as long as the system power is on.
Pins [7 & 9] SMI suspend switch lead
- If your system’s
case has a suspend switch, hook the lead from the switch to
pins 7 & 9 of J15. A suspend switch is used to save
electricity by putting the system into a suspend mode when
the computer is not being used. This switch could also be
used by the Turbo switch on the front of the system, since
this mainboard does not support that function. For this switch to be functional, it must
first be enabled in the Power Management Setup in the BIOS Setup utility.
Pins [17 & 19] Reset switch lead
- Connects to the Reset Switch lead from the system’s
case. The reset switch is used to “cold-boot” the system without actually turning off the
power, reducing wear and tear on the power supply.
Pins [2, 6, 8, 10] Keyboard lock switch lead
- Pins 2 & 6 connect to the Power LED
from the system’s case. Pins 8 & 10 connect to the case-mounted keylock switch.
Pins [14 & 20] Speaker connector
- Connects to the Speaker lead from the system’s
case.
JP6: Clear CMOS RAM
- When closed, the CMOS information is reset to default. All
user-entered information is cleared. To clear the CMOS, first turn the computer off, then
connect a jumper cap over the two pins for a moment. Remove the jumper and power the
system on.
