Appendix C - SBC Configuration Details
Award BIOS Setup
This chapter describes how the BIOS manages the features of your system and explains how to
configure the BIOS in its Setup Menu. The IPC-551 single-board computer is equipped with a system
BIOS chipset from Award Software Inc.
Your application programs (such as word processing, spreadsheets, and games) rely on an operating
system such as DOS or OS/2 to manage such things as keyboard, monitor, disk drives, and memory.
The operating system, in turn, relies on a BIOS (Basic Input and Output system), a program stored on a
ROM (Read-only Memory) chip, to initialize and configure your computer’s hardware. As the interface
between the hardware and the operating system, the BIOS enables you to make basic changes to your
system’s hardware without having to write a new operating system.
The following diagram illustrates the interlocking relationships between the system hardware, BIOS,
operating system, and an application program:

The Setup program built into the Award BIOS lets users modify the basic system configuration. This
special configuration information is then stored in battery-backed RAM so that the PC retains the Setup
information when the power is turned off.
The Award BIOS is a custom version of an industry standard BIOS. It supports Intel/Cyrix/AMD
processors in a standard IBM-AT compatible input/output system. The BIOS provides critical low-level
support for standard devices such as disk drives and serial and parallel ports.
The Award BIOS has been customized by adding important, but non-standard, features such as virus
and password protection as well as special support for detailed fine-tuning of the chipset that controls
the entire PC system.
Descriptions in this chapter will help you configure your system using the BIOS Setup screens.
Note: MultiTech has pre-set the BIOS before shipping the Gatekeeper. In most cases, the user will not need to change
any BIOS settings. However, if any hardware within the Gatekeeper has been changed, or if the boot sequence has been
changed, the user will need to revise the BIOS accordingly.
