Chassis intrusion connector (4-1 pin CHASSIS1) This lead is for a chassis designed with intrusion detection feature. This requires an external detection mechanism such as a chassis intrusion sensor or microswitch. When you remove any chassis component, the sensor triggers and sends a high-level signal to this lead to record a chassis intrusion event. By default, the pins labeled "Chassis Signal" and "Ground" are shorted with a jumper cap. If you wish to use the chassis intrusion detection feature, remove the jumper cap from the pins.

This chapter includes updating the BIOS using the ASUS AFLASH BIOS that is bundled with the support CD. 2. 1 BIOS Setup program Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to "Run Setup". This section explains how to configure your system using this utility. Even if you are not prompted to use the Setup program, you may want to change the configuration of your computer in the future. For example, you may want to enable the security password feature or make changes to the power management settings. This requires you to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the EEPROM. When you start up the computer, the system provides you with the opportunity to run this program. [. . . ] To confirm the password, type the password again and press <Enter>. The password is cleared. Make a copy of the original BIOS on a bootable floppy disk before setting passwords. You will need to upload the BIOS file in case you erase the CMOS RAM in the future. ASUS A7N8X-VM Motherboard 2-19 A note about passwords The BIOS Setup program allows you to specify passwords in the Boot menu. Passwords are not case sensitive, meaning, passwords typed in either uppercase or lowercase letters are accepted. [. . . ]
