SPI Recover Jumper (J41)

The SPI Recover Jumper is used to select BIOS Recovery SPI Flash instead of the BIOS Default SPI
Flash.
Normally Jumper is not installed and board boots on the BIOS Default SPI Flash.
Only in case the Default BIOS gets corrupted and board do not boot:
Then turn off power
Install Jumper (J41)
Try rebooting
After rebooting, remove the Jumper before Default BIOS is recovered by reloading BIOS (for instance
by using latest BIOS upgrade package from web product page).
Verify that Default BIOS has been recovered by making a successful reboot.
Warning: If the jumper (J41) is mounted and you make BIOS Upgrade etc. then the BIOS
!
Recovery SPI Flash will be Upgraded and not the BIOS Default SPI Flash.
This means that in case something goes wrong (power interruption or incorrect BIOS package
used etc.) when Upgrading BIOS, then the BIOS Recovery SPI Flash might get corrupted.
