Chapter 3 Security
3.1 SETTING PASSWORD ON BIOS SETUP UTILITY
You can set a password intended to limit users of starting the system on the BIOS SETUP
Utility.
If you set a password, any user must enter the password for the following operations. This can
increase the security feature:

Starting BIOS SETUP Utility

Starting system
In the BIOS setup menu, the following security passwords can be set.
1. Supervisor password
Users who can start the system are limited. After setting this item, the password
must be entered when starting the BIOS setup menu or the system.
2. User password
Users who can start the system are limited. In addition, the BIOS setup items can
also be limited.
In case users other than the administrator use the N22A, the administrator can
prohibit other users from changing settings.
3. Hard disk password
To prevent illegal use with any device other than the N22A, a password must be
entered when using the HDD by connecting to other devices.
There are two HDD passwords, or HDD master and HDD user passwords.

The HDD master password is intended to release the HDD user password.

The HDD user password is intended to authenticate your computer and the HDD installed in
the computer.
4. I/O LOCK FEATURE

devices, on the BIOS SETUP Utility.
