Book I Chapter 2 Installing Linux Installing SUSE Linux 55 Table 2-3 Using Function Keys at the SUSE Installer Boot Screen Press This To Do This Function Key F1 Get context-sensitive help help information that depends on the currently selected item. Use the up- and down-arrow keys to read the Help screen and the left- and right-arrow keys to jump between topics. You can dismiss the Help screen by pressing Escape. F2 Select a screen resolution that you want the YaST installer to use for its GUI. If the GUI screen fails to appear, you can select Text Mode for a text mode interface. F3 Select the source from where you want to install. The choices are: CD or DVD, network sources with different protocols such as FTP, HTTP, NFS, and SLP (Service Location Protocol). F4 Select the language and keyboard mapping to be used by the boot loader. F5 View kernel messages as the Linux kernel loads. This could help you identify problems if the installation hangs. F6 Update a driver module for new hardware for which drivers may not be on the CD or DVD. You will be prompted to insert the updated driver module on a floppy or CD-ROM after you start the installation. The installer initially picks a rather high screen resolution for the GUI screen (typically, 1280 x 1024 pixels). You should press F2, which brings up a menu from which you can select a more reasonable screen resolution, such as 1024 x 768 pixels. After setting the screen resolution by pressing F2, select Installation from the boot menu and press Enter. This loads the Linux kernel from the DVD and the Linux kernel starts running the YaST installation program. For the rest of the installation, you work with YaST s GUI screens. If you run into any problems during the installation, turn to Chapter 3 of this minibook. That chapter shows how to troubleshoot common installation problems. Starting the SUSE install in YaST YaST the SUSE installer displays a GUI screen (see Figure 2-8) from which you install SUSE Linux on your PC s hard drive and configure it. The left-hand side of the YaST screen shows the list of installation steps, organized into two broad categories of tasks Base Installation and Configuration. An arrow marks the current step. For example, in Figure 2-8, the arrow marks the language selection step. After the step is complete, YaST displays a check mark next to the step.

54 Installing SUSE Linux Installing SUSE Linux from CDs or DVD To install SUSE Linux from CDs or DVD that you have ordered from SUSE, simply insert the first CD or the DVD into your PC s CD/DVD drive and restart your PC (in Windows, choose Start.Shutdown and then select Restart from the dialog box). Note that you may have to enter SETUP and make sure that your PC is set to boot from the CD/DVD drive. If you are using CDs, the installation steps are the same as that for the DVD except that you have to swap CDs when prompted by the installation program. After your PC powers up, a boot loader starts and displays an initial boot screen with a menu of items. Table 2-2 lists these boot menu items and their meaning. As you can see, you can perform a number of tasks from the boot screen, including booting an existing installation from the hard drive and starting a rescue system. Table 2-2 SUSE Installer Boot Menu Items Select This Item To Do This Boot from Hard Disk Boot the PC from a previously installed operating system from the hard drive. Installation Automatically detect hardware and then begin installing SUSE Linux. Installation Disable support for ACPI (Advanced Configuration and ACPI Disabled Power Interface), but otherwise detect hardware and start SUSE installation. Installation Disable potentially troublesome features such as ACPI, APM Safe Settings (Advanced Power Management), and DMA (direct memory access) for IDE interface and start installing SUSE. Select this option if the installation hangs with any of the other options. Manual Installation Control all aspects of installation, including loading device driver modules for your PC s hardware. Rescue System Start a small Linux system in memory so that you can troubleshoot by logging in as root. Memory Test Check to see if there is any problem with the PC s memory. Along the bottom of the SUSE installer boot screen, you see some information about using the function keys F1 through F6. Table 2-3 explains what each of these functions does. You can also provide other installer options as well as Linux kernel options at the Boot Options text box below the boot menu. The installer options control some aspects of the installer s behavior, whereas the kernel options are passed to the Linux kernel that starts when you start the installation. I explain many of these boot options in Chapter 3 of this minibook.

Use arrow keys to select Start Installation/System and press Enter. On the next screen, select Start Installation/Update and press Enter. The installer displays a list of source mediums this is where you indicate where the installer can find the files it needs to perform the installation. 14. Select Network as the source medium and press Enter. The installer prompts you for the network protocol. 15. Select FTP as the network protocol and press Enter. A dialog box prompts you to determine whether to configure the network automatically by using the Dynamic Host Configuration Protocol (DHCP). If your network uses DHCP as most do, select Yes and press Enter. Otherwise, you have to enter the IP address and the name server s IP address at this step. The installer then prompts for the IP address of the FTP server. 16. Enter the IP address of the FTP server that you found in Step 1 (for example, enter 140.221.9.138 for the FTP server mirror.mcs.anl. gov). The installer prompts you if you want to use a username and password to connect to the FTP server. Because the FTP servers support anonymous FTP which means anyone can log in with the username anonymous select No and press Enter. The installer also prompts if you want to use a HTTP proxy. Unless your PC is behind a proxy (which may be the case at some organizations), select No and press Enter. The installer then prompts for the name of the directory where the SUSE files are located. 17. Enter the name of the directory on the FTP server where the SUSE Linux files are located and press Enter. The directory name would be the parent directory of the location where you found the boot.iso file in Step 1. For example, if the boot.iso file is in pub/suse/i386/9.1/boot/, then you should type pub/suse/i386/ 9.1/ and press Enter. The installer displays a message informing you that it is loading data into ramdisk (which refers to an area of memory that acts as a hard drive). When the installer finishes downloading data, the YaST (that s what the SUSE installer is called) installer starts and displays its initial GUI screen. From this point on, the installation steps are the same as the ones for CD/DVD install, which I explain in the next section. You should jump to the point where the YaST installer displays its initial GUI screen.

52 Installing SUSE Linux 2. Click your FTP server link and find the directory that contains the boot.iso file that s the SUSE installer s boot image. The directory depends on the version of SUSE. For example, for version 9.1, the boot.iso file is in the FTP server s pub/suse/i386/9.1/boot/ directory. The file is about 23MB in size. 3. Download the boot.iso file and save it. 4. Burn the boot.iso image onto a CD. Use your PC s CD burner application to burn the ISO image named boot.iso. 5. Go to the PC on which you want to do the SUSE FTP install, insert the boot CD, and restart the PC. If your PC isn t set up to boot from the CD drive, you have to enter SETUP (by pressing a key such as F2 as the PC powers up) and change the order of the boot devices. The PC reboots and after a few moments, a text screen displays a screen with a number of options. Use the arrow keys to move between list items and the buttons on the screen. 6. Use the arrow keys to select the Manual Installation option and press Enter. The installer shows a list of languages. 7. Select the language and press Enter.

Book I Chapter 2 Installing Linux Installing SUSE Linux 51 . Order the latest release of the full distribution from SUSE (www.suse. com) or buy it at a retail computer store. The personal edition of SUSE Linux 9.1 costs approximately $30 U.S. In the following sections, first I go over the steps for performing an FTP install, and then I describe the full SUSE install from CDs or a DVD. Performing an FTP install To install SUSE Linux from one of many FTP servers that mirror the SUSE distribution, you have to perform the following major steps: 1. Download the SUSE boot image from the FTP server and burn a CD with that image. 2. Make a note of the FTP server s IP address and the directory where the SUSE distribution s files are located. 3. Boot the PC with the boot CD and then type a command at the boot prompt to begin an FTP install from the FTP server that you identify by its IP address. If you have a PC that runs Windows and has a high-speed Internet connection, you can use that PC to download the boot image and burn the boot CD. You can also use the PC to look up the IP address of the FTP server. You also need to know the name of the network card installed in your PC because you have to manually load the driver before you can start the SUSE FTP install. You can find the FTP server s IP address at the same time when you download the SUSE installer s boot image. I explain the steps in this section. Installing SUSE from an FTP server can take two hours or more over a typical broadband DSL or cable modem connection to the Internet. Follow these steps to do an FTP install from an FTP server over the network: 1. Use a Web browser to open the list of FTP servers at www.suse.com/ us/private/download/ftp/int_mirrors.html and find a FTP server near you that s marked complete (that means the server has the complete SUSE distribution and all updates). The list of servers is organized by country and it includes both FTP and HTTP (Web) servers. Go to your nearest country and then pick the nearest server that s marked complete. If you are performing this step in Microsoft Windows, open a Command Prompt window (choose Start.Run and type cmd and press Enter) and type ping followed by the name of the FTP server (for example, mirror. mcs.anl.gov). You ll then see the IP address of the FTP server on the next line (for example, 140.221.9.138). Write down that IP address for use later on.

50 Installing SUSE Linux Even if you don t select a single package group from this screen, the installation program installs a plethora of packages and they re all needed simply to run the core Linux operating system and a minimal set of utilities. Each package group requires specific packages to run. The Fedora Core installation program automatically checks for any package dependencies and shows you a list of any required packages you haven t selected. In this case, install the required packages. After you select the package groups you want to install, click Next to continue. The installer then displays a screen informing you that installation is about to begin. Click Next to proceed with the installation. The Fedora Core installer formats the disk partitions and installs the packages. As it installs packages, the installation program displays a status screen to show the progress of the installation, including information such as total number of packages to install, number installed so far, estimated amount of hard drive space needed, and estimated time remaining until the installation is complete. The hard drive formatting and installation can take quite a bit of time so you can take a break and check back in 15 minutes or so. When you come back, you can get a sense of the time remaining from the status screen, which updates continuously. After all the packages install, the installer displays a message informing you that installation is complete. Eject the Fedora Core DVD or CD and click the Exit button to reboot your PC. You can then perform additional configurations and install additional software. Installing SUSE Linux The companion DVD does not include the full SUSE Linux distribution because it s a commercial product. Instead, the DVD includes the ISO image for a SUSE Live CD that enables you to try out the SUSE desktop before you decide whether to buy the full distribution. In this section, I describe the installation process for the full distribution. To try the SUSE Linux Live CD version, simply burn a CD from the SUSE Live Eval ISO image on this book s companion DVD and then boot your PC from that CD. To install the full SUSE distribution, you have two options: . Install the full distribution free of charge directly over a high-speed Internet connection from one of the FTP servers that mirror the SUSE Linux distribution.
