From the Security choice, you can set, change, and delete a user (power-on)
password and a supervisor password.
If you set only a user password, you must type the user password to complete the
system startup.
A supervisor password is intended to be used by a system administrator; it limits
access to the configuration choices. If you set only a supervisor password, you do
not have to type a password to complete the system startup, but you must type the
supervisor password to access all the BIOS Setup Utility program configuration
choices.
If you set a user password for a user and a supervisor password for a system
administrator, you can type either password to complete the system startup. A
system administrator who types the supervisor password has access to the full
BIOS Setup Utility program configuration choices; the system administrator can give
the user authority to set, change, and delete the user password. A user who types
the user password has access to only the limited BIOS Setup Utility program
configuration choices; the user can set, change, and delete the user password, if
the system administrator has given the user that authority.

system startup will not be completed until you type the user password. You can use
any combination of up to seven characters (A–Z, a–z, and 0–9) for the password.
