STL2 Server Board TPS Basic Input Output System (BIOS)

Application software must use standard advanced programmable interrupts (APIs) to access these areas and may not access the data directly.

4.2Setup Utility

This section describes the ROM resident setup utility that provides the means to configure the platform. The setup utility is part of the system BIOS and allows limited control over on-board resources such as the parallel port and mouse. The following topics are covered below:

∙Setup utility operation

∙Configuration CMOS RAM definition

∙Function of the CMOS clear jumper

4.2.1Configuration Utilities Overview

Configuration of on-board devices is done using the setup utility that is embedded in flash ROM. Setup provides sufficient configuration functionality to boot a system diskette or CDROM. The SSU, which is discussed in a separate document, is released on diskette or CDROM. Setup is always provided in flash for basic system configuration.

The configuration utilities modify CMOS RAM and NVRAM under direction of the user. The BIOS POST routines and the BIOS Plug-N-Play Auto-configuration Manager accomplish the actual hardware configuration. The configuration utilities always update a checksum for both areas, so that any potential data corruption is detectable by the BIOS before the hardware configuration takes place. If data is corrupted, the BIOS requests that the user reconfigure the system and reboot.

4.2.2Setup Utility Operation

The ROM-resident setup utility configures only on-board devices. The setup utility screen is divided into four functional areas. Table 4-1 describes each area:

	Table 4-1. Setup Utility Screen
Functional Area	Description
Keyboard Command Bar	Located at the bottom of the screen. This bar displays the keyboard commands
	supported by the setup utility.
Menu Selection Bar	Located at the top of the screen. Displays the various major menu selections
	available to the user. The server setup utility major menus are: Main Menu,
	Advanced Menu, Security Menu, System Menu, Boot Menu, and the Exit Menu.
Options Menu	Each Option Menu occupies the left and center sections of the screen. Each menu
	contains a set of features. Selecting certain features within a major Option Menu
