Selecting boot options for SUSE Linux 10

Get six boot options for SUSE Linux 10 in this book excerpt.

When the boot splash screen has finished, you will be asked to select how you want to install SUSE Linux 10, as...

well as some other helpful options for booting your system (see Figure 1-2).

The boot menu offers more than just installation options, although the most common selection is the standard Installation item. We discuss the other six options in detail because at some point in the life of a SUSE Linux enterprise user you will likely need to use the others.

  • Boot from hard disk: This is the default setting if you do not interact with the boot sequence. It's the default because your system automatically reboots as part of the installation process to load the kernel that is installed on your hard drive during the initial phases of the installation process. If you forget to remove the installation media, the system will still boot off the hard disk and the install routine can continue.
  • Installation: This is the standard option that most users should select. It will boot from the CD and start the install routine (YaST). We discuss the rest of the process in the remainder of this chapter.
  • Installation -- ACPI disabled: Advanced Configuration and Power Interface (ACPI) is a feature of most new processors that controls power management and the way interrupts are handled by the system hardware. You should select this option if you encounter problems during the installation process, such as if your computer system goes to sleep (blanks the screen and powers down the drives) and if pressing the appropriate keystroke does not wake it up again.
  • Installation -- Safe settings: As with the ACPI Disabled installation method, this turns off some of the features of the kernel that can cause problems with buggy or old system hardware. You should select this option if you encounter problems during installation, and they do not seem related to power management.
  • Rescue system: The Rescue System enables you to correct system problems, such as disk corruption or lost passwords, by booting from the installation media and subsequently correcting system problems. The Rescue System is quite a feature-rich system that you can use to load and edit filesystems, as well as change the settings of an installed system.
  • Memory Test: SUSE has been very kind and integrated a memory test suite in the system boot menu. The memory test will run long and exhaustive tests on your system's memory and warn you of any anomalies that it encounters on the way. We have used this a few times with systems that don't quite seem to be running as we expect, and it has been able to tell us that a DIMM (Dual In-Line Memory Module) has indeed failed.

    In this chapter, we select the standard Installation option in the boot menu.

    SUSE Linux 10 has changed the original boot splash screen to be something more akin to the Windows bootup (see Figure 1-3). While this is fine for first-time users, it is something that will infuriate hard-core Linux users. SUSE is aware this may be a problem for some users, and pressing ESC while the system boots up will allow you to see the kernel and init messages.

    So far, the system has booted a minimal Linux kernel that is sufficient to run the installation process and execute the SUSE Linux 10 installer and the various utilities that it uses to probe and configure your system. SUSE's YaST installer now begins to collect information that it will use to configure your system to match your personal and hardware requirements.
