7. BIOS Setup

PC-686BX(NLX)-LV, PC-686BX(NLX)-LVV

Password disabled

If the password is enabled, the system prompts the user to enter a password each time

the user enters the Setup utility. This prevents unauthorized users from making any

changes to the system configuration.

Also, if the password is enabled, the BIOS can also request the user to enter the

password whenever the user reboots the system. This prevents unauthorized use of

the computer.

Use the Security Option field in the BIOS Features Setup menu (see section 3) to

specify when password input is required. When the security option is set to "System",

password input is required both to boot the system and to enter Setup. When the

security option is set to "Setup", password input is only required to enter Setup.

Note!

Once a password has been set, the password function cannot be
disabled without first entering the password. Ensure you look after
your password carefully.
