Intel NUC Board NUC5i3MYBE Technical Product Specification

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.

NOTE

The MEBX_RESET header has a non-conductive protective cap installed. This must be removed

before installing the MEBX_RESET jumper, and reinstalled before reassembling the system. Failure

to do so may result in inadvertent shorting of the bottom cover screw to the header during bottom

cover reassembly (see Figure 20).
