SAI2 Server Board TPS Basic Input Output System (BIOS) 3.2 Setup 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 3.2.1 Configuration 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 CD-ROM. The System Setup Utility, which is discussed in a separate document, is released on diskette or CD-ROM. Setup is always provided in flash for basic system configuration. The configuration utilities modify CMOS RAM and Non-Volatile Random Access Memory (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. 3.2.2 Setup Utility Operation The ROM-resident setup utility configures only on-board devices. The setup utility screen is divided into four functional areas. The table below describes each area: Table 6.
