System and Setup Password Features
NOTICE:
The password features provide a basic level of security for the data on your system. If your data requires
more security, use additional forms of protection, such as data encryption programs.
NOTICE:
Anyone can access the data stored on your system if you leave the system running and unattended
without having a system password assigned or if you leave your system unlocked so that someone can disable the
password by changing a jumper setting.
Your system is shipped to you without the system password feature enabled. If system security is a concern,
operate your system only with system password protection.
To change or delete an existing password, you must know the password (see "Deleting or Changing an
Existing System Password" on page 39). If you forget your password, you cannot operate your system or
change settings in the System Setup program until a trained service technician changes the password
jumper setting to disable the passwords, and erases the existing passwords. This procedure is described in
"Disabling a Forgotten Password" on page 101.
Using the System Password
After a system password is assigned, only those who know the password have full use of the system. When
the
System Password option is set to Enabled , the system prompts you for the system password after the
system starts.
NMI Button This field enables/disables the NMI button on the front panel.
NOTICE:
Use the NMI button only if directed to do so by
qualified support personnel or by the operating system's
documentation. Pressing this button halts the operating system
and displays a diagnostic screen.
