• If both the supervisor and user passwords are set, users can enter either the
supervisor password or the user password to access setup. Access to setup
corresponds to which password is entered.
• Setting the user password restricts who can boot the computer. The password
prompt is displayed before the computer is booted. If only the supervisor password
is set, the computer boots without asking for a password. If both passwords are
set, the user can enter either password to boot the computer.
Tabl e 23 shows the effects of setting the supervisor password and user password. This
table is for reference only and is not displayed on the screen.
6.10 Remote Access Configuration
Remote access using serial console redirection allows users to monitor the MPCBL0010
SBC boot process and run the MPCBL0010 SBC 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.
Note: The default settings used for console redirection to the serial port are 115,200, n, 8, 1,
and no flow control.
Tabl e 24 shows the escape code sequences that may be useful for things like BIOS
setup if function keys cannot be sent directly from a terminal application:
