SPI Recover Header (SPI_HEADER)
The SPI Recover Jumper is used to select BIOS Recovery Flash instead of BIOS Default Flash.
Normally SPI Recovery Jumper is not installed and board boots on the BIOS Default Flash. Only in case
the Default BIOS gets corrupted (board do not boot) follow the procedure:
1. First try to use the Load Default BIOS Settings Jumper, see previous page. If problem remains
then continue.
2. Turn off power.
3. Install "SPI Recover Module" in SPI header connector (SPI_HAEDER).
4. Turn on power.
5. After the boards has booted remove the module.
6. Upgrade the BIOS.
7. When BIOS upgrade is completed then turn off power completely (inclusive Standby +5V).
8. Wait for 1 minute.
9. Turn on power. System will automatically reboot 4-5 times within 1 minute.

SPI Connector (SPI_HEADER)
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.

Description
CLK
Serial Clock
3.3V Standby Voltage power line. Normally output power, but when Motherboard is
SB3V3
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
The ISOLATE# input, active low, is normally NC, but must be connected to GND
ISOLATE#
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
SPI Data I/O: A bidirectional signal used to support the new Dual
SPI_IO2_#WP
IO Fast Read, Quad IO Fast Read and Quad Output Fast Read modes.
This signal is not used in Dual Output Fast Read mode.
SPI Data I/O: A bidirectional signal used to support the new Dual
SPI_IO3_#HOLD
IO Fast Read, Quad IO Fast Read and Quad Output Fast Read modes.
This signal is not used in Dual Output Fast Read mode.
