2.The following message will appear:

Enter password

Type the current password followed by a space.

3.Press Enter.

Unattended Mode

If the unattended start mode is active, you must remove it before you can change or remove the power-on password because the password prompt does not appear when the unattended start mode is set.

￿4￿ Set unattended start mode

The unattended start mode locks the keyboard and mouse when the system is powered on, but it allows the operating system and startup files to be loaded. The keyboard and mouse remain locked until you enter the power-on password.

This mode is useful for unattended operations and for network servers because it allows authorized network users access to information on the server but prohibits unauthorized access via the system keyboard and mouse.

When the server is in the unattended mode, the password prompt will not appear unless an attempt to start the system from a diskette or other removable media is issued. If you start the server from a removable media, the password prompt will appear and you must enter the correct power-on password to continue.

Power-on Password

A power-on password must be set on the server before you can set the unattended start mode because it locks the keyboard and mouse when the system is powered on.

￿5￿ Set privileged-access mode

This option allows you to set a privileged-access password (also called an administrator password). If set, this password is needed to start the system programs.

Before the privileged-access password can be set, the privileged-access switch at location JMP2 on the system board must be placed in the change state (position 0).

Attention!

Do not forget the privileged-access password. If you forget this password, the system board must be replaced before you can regain access to your system.
