Testing the Media Note If you don’t get this screen, then it may be because your computer is not configured to boot off the CD-ROM drive by default. In this case, you may need to adjust the configuration of your machine by changing the boot sequence of your computer, so that it begins with the CD-ROM drive. The best way to do this is to reboot your computer, and take it into the BIOS setup menu immediately after boot up. The exact way to access the BIOS setup menu varies from machine to machine, but it usually involves hitting a button such as F2 or F10 or Escape. Check your motherboard’s manual if you have it, or follow the instructions on screen immediately after the reboot. The dialog asks you to select whether to install in graphical or text mode. Text mode is suitable in situations where a minimal configuration is required, or where there is a problem with the display. We will conduct our installation in graphical mode, so just press the Enter key. When you’ve selected the mode of installation, the boot program proceeds by displaying a flurry of messages on the screen. Don’t be alarmed by this - this is perfectly normal in a Linux operating system boot up. When Linux boots up, it stays in text mode briefly to perform a few routine checks and processes, and then launches the installation in graphical mode after that. So, let’s deal with these initial questions of the installation. Testing the Media In version 9, Red Hat has introduced a media test module into the installation process. The purpose of the media test module is to eliminate one of the most frequent sources of installation problems - defects in the CDs themselves. As shown below, the module asks you whether you would like to test the CD media before proceeding with the installation: 18
