LPI Linux Certification in a Nutshell, 2nd Edition

Objective 1: Configure Fundamental BIOS Settings

Setting up a PC for Linux (or any other operating system) requires some familiarity with the devices installed in the system and their configuration. Items to be aware of include modems, serial and parallel ports, network adapters, SCSI adapters, hard drives, USB controllers, and sound cards. Many of these devices, particularly older ones, require manual configuration of some kind to avoid conflicting resources. The rest of the configuration for the system hardware is done in the PC's firmware, or Basic Input/Output System (BIOS).

BIOS

The firmware located in a PC, commonly called the BIOS, is responsible for bringing all of the system hardware to a state at which it is ready to boot an operating system. Systems vary, but this process usually includes system initialization, the testing of memory and other devices, and ultimately locating an operating system from among several storage devices. In addition, the BIOS provides a low-level system configuration interface, allowing the user to choose such things as boot devices and resource assignments. Quite a few BIOS firmware vendors provide customized versions of their products for various PC system architectures. Exams do require an understanding of the basics. For example, a laptop BIOS may differ significantly from a desktop system of similar capability from the same manufacturer. Due to these variations, it's impossible to test specifics, but the LPIC Level 1 exams do require ...
