Chapter 7 . Installing Linux 249 The MD5SUM file I downloaded previously from the download directory was called KNOPPIX_V4.0.2CD-2005-09-23-EN.iso.md5. It contained this content: 1188f67d48c9f11afb8572977ef74c5e *KNOPPIX_V4.0.2CD-2005-09-23-EN.iso As you can see, the checksum (first string of characters shown) that is output from the ISO image matches the checksum in the MD5 file, so you know that the image you downloaded is the image they put on the server. As long as you got the image from a reliable site, you should be ready to burn the CD. With your Linux distribution in hand (either the book s DVD or CD, or the set of CDs you got elsewhere), proceed to Appendix A for details on burning your own CDs or DVDs. After that, instructions for installing the distributions from the DVD can be found in separate chapters for each distribution (Chapters 8 19). Before you proceed, however, there s some information useful for nearly every Linux system you are installing. Exploring Common Installation Topics Before you begin installing your Linux distribution of choice, there is some general Linux information you should understand. Reading over this information might help you avoid problems or keep you from getting stuck when you install Linux. Knowing Your Computer Hardware Every Linux will not run on every computer. When installing Linux, most people use a Pentium-class PC. There are Linux systems that are compiled to run on other hardware, such as Mac PowerPCs or AMD 64-bit computers. However, the distributions provided with this book run only on 32-bit Pentium-class PCs. Minimum hardware requirements from the Fedora Project are pretty good guidelines for most Linux systems: . Processor The latest version of Fedora Core recommends that you at least have a Pentium-class processor. For a text-only installation, a 200 MHz Pentium is the minimum, while a 400 MHz Pentium II is the minimum for a GUI installation. If you have a 486 machine (at least 100 MHz), consider trying Slackware. The problem is that many machines that old have only floppy disks, so you can t use the CD or DVD that comes with this book. In that case, you can try ZipSlack (www.slackware.com/zipslack), which is a Slackware version that comes on about 30+ floppy disk images or a 100MB zip disk and can run on a 486 with at least 100MB of disk space.
