Introduction

Chapter 4 BIOS Setup

This chapter describes the BIOS Setup menus and the various screens used for configuring the LittleBoard 550. Some features in the Operating System or application software may require configuration in the BIOS Setup screens.

This section assumes the user is familiar with general BIOS Setup and does not attempt to describe the BIOS functions. Refer to the appropriate PC reference manuals for information about the onboard ROM-BIOS software interface. If Ampro has added to or modified the standard functions, these functions will be described.

The options provided for the LittleBoard 550 are controlled by BIOS Setup. BIOS Setup is used to configure the board, modify the fields in the Setup screens, and save the results in the onboard configuration memory. Configuration memory consists of portions of the CMOS RAM in the battery- backed real-time clock chip and the flash memory.

The Setup information is retrieved from configuration memory when the board is powered up or when it is rebooted. Changes made to the Setup parameters, with the exception of the time and date settings, do not take effect until the board is rebooted.

Setup is located in the ROM BIOS and can be accessed, when prompted using the <Del> key, while the board is in the Power-On Self Test (POST) state, just before completing the boot process. The screen displays a message indicating when you can press <Del>.

The LittleBoard 550 BIOS Setup is used to configure items in the BIOS using the following menus:

•BIOS and Hardware Settings

•Reload Initial Settings

•Load Factory Default Settings

•Exit, Saving Changes

•Exit, Discarding Changes

Table 4-1 summarizes the list of BIOS menus and some of the features available for LittleBoard 550. The BIOS Setup menu offers the menu choices listed above and the related topics and screens are described on the following pages.
