I. FAN Connectors (FAN)
These are the 3-pin connectors for both CPU and chassis fans.
J. Soft Power Connector
The soft power connector is part of jumper block
J24
(pins 6 and 8). This board uses the chipset for power
management, including turning on and off the system. If the power button function option in the BIOS
Power Management menu is set to “On/Off” (which is the default), pressing the power button once after
the BIOS has booted up will turn the system on and off. If the power button function is set to Suspend,
pressing the power button once will wake up the system or send it to Suspend mode. In this case, you
cannot turn the system off unless you shut down through the Windows operating system or you hold the
power button down for four seconds (BIOS-dependent feature).
K. Hardware Reset Switch Connector Installation
The reset switch on your chassis case provides you with the Hardware Reset function, which is the same
as power on/off, except that the system will immediately execute a cold start after the reset button is
pushed. The reset switch needs to be connected to jumper block
J24
(pins 5 and 7).
L. Flash Utility
You can upgrade the BIOS of this motherboard by using the Flash Utility (see
p.47
). Check the Tyan web-
