This connector provides a
Soft Power Connector
The Soft Power Connector is located on pins 6 and 8 of jumper block J3. Pressing the Soft Power Button will turn the sytem on and off. Holding this button for more than four seconds (when the system is on) will power down the system. Pressing it again will reboot the system.

The Trinity ATX provides a
CMOS RTC
The VIA MVP3 AGPset includes a Real Time Clock (RTC) circuit, which provides the date and time for the system. If the external battery for the RTC is low, you will lose your BIOS settings. Normally the life span of an external battery is 2 years. If yours is running low, you will need to replace it with a new 3V lithium battery (Sony CR2032).
USB
There are two ATX Universal Serial Bus ports on the back of the board. The board also has an additional USB header (USB2, USB3) on the edge of the board near the third PCI slot. This header can be used to connect a USB port on the front of the chassis.
Flash EEPROM
The Trinity ATX uses flash memory to store BIOS programs. It can be easily updated if necessary using the flash utility (see page 57). Tyan does not recommend flashing the BIOS unnecessarily. Check the Tyan web site for the latest BIOS revision.
