Password Clear DIP Switch
If the user and/or administrator password is lost or forgotten, both passwords may be
cleared by moving the password clear DIP switch into the clear position. The EFI BIOS
determines if the password clear jumper is in the clear position during EFI BIOS POST
and clears any passwords if required. The password clear DIP switch must be restored
to its original position before a new password will stay set.
Remote Access Configuration
Remote access using serial console redirection allows users to monitor the MPCBL0050
boot process and run the MPCBL0050 EFI BIOS Setup from a remote serial terminal.
Connection is made directly through a serial port.
The console redirection feature is useful in cases where it is necessary to communicate
with a processor board in an embedded application without video support.
The default settings used for console redirection to the serial port are 115200, n, 8, 1,
and no flow control.

Boot Device Priority
The boot device priority is stored in non volatile RAM (NVRAM), is static across reboots
will not change except for in the following conditions:
As soon as the board boots one time, the boot order will be fixed until changed by the
user. A manual save of boot order by user is not needed to fix the boot order.
Above mentioned NVRAM refers to a small portion of the FWH (Firmware Hub). When
the NVRAM is empty or does not contain valid boot order information, the EFI BIOS
automatically determines a boot order upon next reboot. If a USB device is connected
to the board when there is no boot order saved, the USB device will automatically be
placed at the top of the boot order.
Once the boot order is static, if a hard drive or any other boot device is added (such as
USB boot device), it will be added at the bottom of the boot order list.
If a boot device needs to be added as a permanent boot device, the user should re-
order the boot devices in EFI BIOS Boot Device Priority setup menu.

the default EFI BIOS setup. This will erase the current boot order in NVRAM and EFI
BIOS will automatically determine a new boot order upon next reboot of the board.
