Some of the features include: A lockable cover using a customer supplied padlock to help secure computer hardware components A u-bolt and a lockable cable can be installed to secure the computer to a desk or table. A power-on password to help prevent unauthorized use of the computer An administrator password to authorize computer-setup changes An unattended start mode to enable the computer to operate without input from the keyboard or mouse A selectable startup sequence to prevent use of unauthorized programs to bypass security controls Selectable disabling of diskette and IDE drives to prevent unauthorized use I/O port control to disable input and output functions of the serial and parallel ports and their attached devices The use of some features also depends on your operating system and network software. For detailed information about using these security features, see the PC 300GL User Guide.
