User Password: able to enter but no right to change the options of setup menus.
Type the password, up to eight characters in length, and press <Enter>. The
password typed now will clear any previously entered password from CMOS
memory. You will be asked to confirm the password. Type the password again
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password. To disable a password, just press <Enter> when you are
prompted to enter the password. A message will confirm the password will be
disabled. Once the password is disabled, the system will boot and you can enter
Setup freely.
PASSWORD DISABLED.
When a password has been enabled, you will be prompted to enter it every time
you try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration. Additionally, when a password is enabled, you
can also require the BIOS to request a password every time your system is
rebooted. This would prevent unauthorized use of your computer. You determine
when the password is required within the BIOS Features Setup Menu and its
Security option (see Section 3). If the Security option is set to “System”, the
password will be required both at boot and at entry to Setup. If set to “Setup”,
prompting only occurs when trying to enter Setup
