(Intel

MEBX) Reset Header

The Intel

MEBX reset header (see Figure 15) allows you to reset the Intel ME

configuration to the factory defaults. 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 Intel MEBX password to the default value (admin).

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.
