The Intel MEBX reset header (see Figure 22) 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.

Jumper Setting Configuration
The BIOS uses current configuration information and passwords
1-2
for booting.
After the POST runs, Setup runs automatically. The
2-3
maintenance menu is displayed.
Note that this Configure mode is the only way to clear the
BIOS/CMOS settings. Press F9 (restore defaults) while in
Configure mode to restore the BIOS/CMOS settings to their
default values.
The BIOS attempts to recover the BIOS configuration. A
None
recovery CD or flash drive is required.
