2 This document provides technology support information for 915G chipset-based Intel(R) Desktop Boards that use the Novell* Linux* Desktop 9 operating system (OS) with kernel This document also helps configure Intel(R) Desktop Boards that use the Intel(R) 915G chipset so they can support key technologies BEFORE a Linux-based operating system is installed (Pre-OS). Information is also provided in configuring these Intel(R) Desktop Boards to support key technologies AFTER operating system installation (Post-OS). NOTE: This document is intended for use only on systems built with an 915G Chipset-based Intel(R) product to see if a specific technology is supported by your particular Intel(R) ======================== 2 - Document Conventions ======================== To enhance readability, the following conventions are used throughout the rest of this document: -- Commands are listed either as stand-alone indented lines such as: cd /tmp make install or surrounded by single quotation marks when used in sentences such as: Enter the 'make install' command. -- Special callouts, buttons, and paths are placed within double quotation marks. For example: Browse to the "/root/test" dir and double-click on the "test.bin" file. Always press the "Enter" key after each command entry. -- Bullet items are called out with a double dash "--" prefix at the left side of the page. ================================= 3 - Supported Linux Distributions ================================= Intel(R) has performed limited validation on 915G chipset-based Intel(R) Desktop Boards and verified basic functionality of key technologies described in this document for the Novell* Linux* Desktop 9 operating system running with a standard kernel. Linux drivers for these Intel(R) Desktop Boards have also been released to major distributions. Thus, we hope that future releases of most Linux distributions contain native hardware support for the above Intel(R) Desktop Boards.
