Technical Reference Table 25. BIOS Setup Configuration Jumper Settings Function/Mode Normal Configure Jumper Setting 1-2 2-3 Configuration The BIOS uses current configuration information and passwords for booting. After the POST runs, Setup runs automatically. The 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. Recovery None The BIOS attempts to recover the BIOS configuration. A recovery CD or USB flash drive is required. 2.4 Intel® Management Engine BIOS Extension (Intel® MEBX) Reset Header The Intel® MEBX reset header (see Figure 14) allows you to reset the Intel AMT 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. • Delete any user entered information, including PID/PPS and user entered Hash Certificates. USB key and remote configuration data will be removed if the parameters are not default parameters. • 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 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. 55
