The SPI Connector is normally not used. If however a SPI BIOS is connected via the SPI Connector
then the board will try to boot on it.

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