SECURITY FEATURES

ADMINISTRATIVE PASSWORD

The administrative password protects several sensitive Setup options from being viewable to a user unless the password is entered. These sensitive fields are viewable unless the administrative password is set.

BIOS PASSWORD

A BIOS password feature provides security during the boot process. A password can be entered using the Setup utility, and will be required on boot up before normal operation of the system can commence. To enable, disable, or change the password, refer to the Setup program options in the appendix.

If the password is forgotten, it can be cleared by turning off the system and setting the "password clear" jumper to the clear position.

SETUP ENABLE SWITCH

A baseboard configuration switch controls access to the BIOS Setup utility. By setting switch SW5 to the ON position, the user is prevented from accessing the Setup utility during the Power-On Self Test or at any other time. The message prompting the user to press <F1> to enter setup is also disabled
