"LOAD DEFAULT BIOS SETTINGS" JUMPER (JP1)
The "Load Default BIOS Settings" Jumper (JP1) can be used to recover from incorrect BIOS settings. As an
example, an incorrect BIOS setting which causes the attached display not to turn on can be erased by this
Jumper.
The Jumper has 6 positions: Pin 5-6 are used for this function.

ALWAYS ON JUMPER SETTING (JP1)
When jumper is installed in the (JP1) Pin 1-2 "Always On" position, then the Board will automatically power
up, when the external power supply is switched ON.
When jumper is in not mounted, then Always On feature is disabled and it might be necessary to activate
the power on buttom (PWRBTN_IN#) at the Front Panel connector (FRONTPNL) in order to switch on the
board.

SPI CONNECTOR (J30)
The SPI Connector is normally not used. If however a SPI BIOS is connected via the SPI Connector then the
board will attempt to boot from it.

DESCRIPTION
CLK
Serial Clock
3.3 V Standby Voltage power line. Normally output power, but when Motherboard is
SB3V3
turned off then the on-board SPI Flash can be 3.3 V power sourced via this pin.
CS0#
CS0# Chip Select 0, active low.
ADDIN
ADDIN input signal must be NC.
MOSI
Master Output, Slave Input.
The ISOLATE# input, active low, is normally NC, but must be connected to GND when
ISOLATE#
programming the SPI flash. Power Supply to the Motherboard must be turned off
when loading SPI flash. The pull up resistor is connected via diode to 5VSB.
