again intervene and allow the user another opportunity to adjust the BIOS settings.

detect an issue or was disabled by the user, then one of the alternate recovery options
described in Sections 3.4.2 through 3.4.4 can be used.

3.4.2 Back to BIOS 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 needing to open
the s
ystem chassis to access the BIOS jumper. When the Back to BIOS button is
depressed, both the button and a red LED located on the Intel Desktop Board DP67BG
diagnostic LED bank will illuminate. 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 DP67BG Product Guide.
