2.4 Intel® Management Engine BIOS Extension (Intel®
MEBX) Reset Header
The Intel® MEBX reset header (see Figure 20) allows you to resynchronize the Intel ME firmware to
the board’s BIOS. Momentarily shorting pins 1 and 2 with a jumper (not supplied) will accomplish
the following:
• Return all Intel ME parameters to their default values.
• Reset the time and date to their initial values.
CAUTION
Always turn off the power and unplug the power cord from the computer before installing an MEBX
reset jumper. The jumper must be removed before reapplying power. The system must be allowed
to reach end of POST before reset is complete. Otherwise, the board could be damaged.
NOTE
After using the MEBX Reset, a “CMOS battery failure” warning will occur during the next POST. This
is expected and does not indicate a component failure.
