Dell Inspiron 2000 - Manual (Page 58)

Passwords
When you receive the computer, the password features are disabled so that you can assign passwords. If you assign a password and then forget it, you have limited access
to the computer, but you must enter the password to access the system setup program. Refer to Appendix B, "Using the System Setup Program," of the Reference and
Troubleshooting Guide for information on assigning a password.
NOTICE: The password features provide a high level of security for the data in the computer. However, they are not foolproof. If your data requires more
security, it is your responsibility to obtain and use additional forms of protection, such as data encryption programs or
PC Cards with encryption features.
Physically Securing the Computer
The security cable slot lets you attach a commercially available antitheft device to the computer. Antitheft devices for portable computers usually include a segment of metal-
stranded cable with an attached locking device and associated key. Complete instructions for installing this kind of antitheft device are usually included with the device. To
prevent unauthorized removal of the computer, loop the cable around an immovable object, insert the locking device into the security cable slot, and lock the device.
Disabling the Parallel Port
You can disable the parallel port to prevent unauthorized access to the computer through an external parallel device. To disable the parallel port, perform the following steps:
Enter the system setup program.
Press the right arrow key to select the Advanced screen.
Press the down arrow key to highlight I/O Device Configuration.
Set the Parallel Port option to Disabled.
Disabling the parallel port also prevents the unauthorized downloading of data from that port.
