When an IT administrator first enters the Intel MEBx configuration menu with the default password, he or she must change
the default password before any feature can be used.
The new password must include the following elements:
Eight characters, no more than 32
One uppercase letter
One lowercase letter
A number
A special (Non-alphanumeric) character, such as !, $, or ; excluding the : " and , characters.)
NOTE: The underscore ( _ ) and spacebar are valid password characters but do NOT add to the password complexity.
NOTE: The password can be reset to the default setting (admin) by shutting down the system, removing AC and DC
power and performing a RTC reset.
