3.4.2 Back to BIOS (B2B) Button
A second recovery option is to use the Back to BIOS button that is located on the
board’s back panel. This button provides a convenient method of invoking the BIOS
setup menu, as shown in Figure 3.2, in a safe, bootable mode without opening the
system chassis to access the BIOS configuration jumper. When the Back to BIOS
button is depressed, both the button and the red WD Fire/B2B LED located on the Intel
Desktop Board DX58SO2/DX58OG Diagnostic LED bank will light. The F9 key can then
be used to restore all BIOS settings to defaults at this point or specific performance
settings can be individually revised by the user to restore system stability. Additional
information regarding this feature can be found in the Intel Desktop Board DX58SO2
(or DX58OG) Product Guide.

3.4.3 BIOS Configuration Jumper
A third recovery option is to use the BIOS configuration jumper on the board to force
the board to boot to BIOS Setup in a safe mode. The user will need to open their
system chassis to access this jumper. Refer to the Intel Desktop Board DX58SO2 (or
DX58OG) Product Guide for additional information on using the BIOS jumper for
resetting purposes.
