BIOS is a ROM-based configuration utility that displays the system’s configuration status and provides you with options to set the system parameters. This program should be executed under the following conditions: • When changing the system configuration • When a configuration error is detected by the system and you are prompted to make changes to the Setup program • • • • These parameters are stored in non-volatile battery-backed-up CMOS RAM that saves this information even when the power is turned off. When the system is turned back on, the system is configured with the values found in CMOS. When redefining the communication ports to prevent any conflicts When making changes to the Power Management configuration When changing the password or making other changes to the security setup Normally, CMOS setup is needed when the system hardware is not consistent with the information contained in the CMOS RAM, whenever the CMOS RAM has lost power, or the system features need to be changed. With easy-to-use menus, you can configure such items as: • • • • When resetting the system clock Hard drives, diskette drives, and peripherals Video display type and display options Password protection from unauthorized use Power management features The settings made in the Setup program intimately affect how the computer performs. It is important, therefore, first to try to understand all the Setup options, and second, to make settings appropriate for the way you use the computer. Preparing for BIOS Configuration To access the BIOS, you will need a computer with HyperTerminal (or any telnet client) installed and the serial cable that is supplied in the NSA 1083 package.

Power Management Setup EPP Mode Select Power Management Setup lets you control the system power. The system has various power-saving modes — including powering down the hard disk, turning off the video, suspending to RAM, and software power down — that allows the system to be automatically resumed by certain events. Select EPP port type 1.7 or 1.9. ECP Mode Use DMA The power-saving modes can be controlled by timeouts. If the system is inactive for a time, the timeouts begin counting. If inactivity continues and reaches the defined timeout period, the system enters a powersaving mode. If any item in the list of Reload Global Timer Events is enabled, then any activity on that item will reset the timeout counters to zero. When the on-board parallel port is set to ECP mode, the parallel port can use DMA3 or DMA1. PWR LED after PWR-ON Set the behavior of PWR LED after the appliance is power on. By default, the PWR LED is set to turn on after powering on the appliance. If the system is suspended or has been powered down by software, it can be resumed by a wake up call that is generated by incoming traffic to a modem, a LAN card, a PCI card, or a fixed alarm on the system real-time clock. LAN ByPass Function This set of options allow you to control the bypass function that NSA 1083 provides. By configuring LAN bypass, you can help ensure that traffic will still be able to pass through the appliance even when there is a problem with the platform. Configuring the bypass function is especially recommended for gateway security appliances. For more information about the bypass function, refer to Appendix C.

PnP/PCI Configuration Screen Soft-Off by PWR-BTTN This defines the power-off mode when using an ATX power supply. The Instant Off mode allows powering off immediately upon pressing the power button. In the Delay 4 Sec mode, the system powers off when thepower button is pressed for more than four seconds or enters the suspendmode when pressed for less than 4 seconds. The default value is Instant Wake-Up by PCI Card This allows the system to wake up from a signal received from a PCI card such as a LAN card. Power On by Ring This enables or disables the powering on of the system through the modem connected to the serial port or LAN. Reload Global Timer Events The Primary IDE 0, Secondary IDE 0, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can prevent the system from entering a power saving mode or can awaken the system from such a mode. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. Available options for each type of I/O event include Enabled and Disabled (default). Refer to the following sections for information on the options that you can configure on this screen. Reset Configuration Data Normally, you leave this field Disabled.
