If you install from the ISOs published as quarterly update they can be identified by the string QU in the name , the installer cannot update itself, because this feature has been disabled in the update media. To download installer updates, YaST needs network access. By default, it tries to use DHCP on all network interfaces. If there is a DHCP server in the network, it will work automatically.
If you need a static IP setup, you can use the ifcfg boot argument. The installer self-update is executed before the language selection step. This means that progress and errors which happen during this process are displayed in English by default. On machines equipped with a traditional BIOS, alternatively, press F2 in the boot menu and select the language from the list.
Although this feature was designed to run without user intervention, it is worth knowing how it works. If you are not interested, you can jump directly to Section 3.
No matter which of the following options you use, only the installer self-update repository URL is expected, for example:. For more details, see Section 2. If you specify a URL, it will take precedence over any other method.
If none of the previous attempts worked, the fallback URL defined in the installation media will be used. When the updates repository is determined, YaST will check whether an update is available. If so, all the updates will be downloaded and applied to the installation system. Finally, YaST will be restarted to load the new version and the welcome screen will be shown.
If no updates were available, the installation will continue without restarting YaST. Update signatures will be checked to ensure integrity and authorship. If a signature is missing or invalid, you will be asked whether you want to apply the update.
Some packages distributed in the self-update repository provide additional data for the installer, like the installation defaults, system role definitions and similar. If the installer finds such packages in the self-update repository, a local temporary repository is created, to which those packages are copied. They are used during the installation process, but at the end of the installation, the temporary local repository is removed.
Its packages are not installed onto the target system. This additional repository is not displayed in the list of add-on products, but during installation it may still be visible as SelfUpdate0 repository in the package management.
However, the following points should be considered:. Packages are not installed in the usual way: They are uncompressed only and no scripts are executed. Files from the packages override the files from the original installation media. This means that the update packages might not need to contain all files, only files that have changed.
Unchanged files are omitted to save memory and download bandwidth. Currently, it is not possible to use more than one repository as source for installer self-updates. The Language and Keyboard Layout settings are initialized with the language you chose on the boot screen. If you did not change the default, it will be English US.
Change the settings here, if necessary. Changing the language will automatically preselect a corresponding keyboard layout. Override this proposal by selecting a different keyboard layout from the drop-down box. Use the Keyboard Test text box to test the layout. The language selected here is also used to assume a time zone for the system clock. This setting can be modified later in the installed system as described in Chapter 6, Changing language and country settings with YaST.
Read the license agreement. It is presented in the language you have. Translations are available via the License Language drop-down box.
Proceed with Next if you agree to the terms and conditions. If you do not agree, click Abort to terminate the installation. After booting into the installation, the installation routine is set up. During this setup, an attempt to configure at least one network interface with DHCP is made. In case this attempt has failed, the Network Settings dialog launches now. Choose a network interface from the list and click Edit to change its settings. Use the tabs to configure DNS and routing.
In case DHCP was successfully configured during installation setup, you can also access this dialog by clicking Network Configuration at the the Installation Settings step.
It lets you change the automatically provided settings. If at least one network interface has been configured via boot parameters see Section 2. Switch to a console with Ctrl — Alt — F2. Install the libstoragemgmt extension by running extend libstoragemgmt. Now you have access to the lsmcli command. For more information, run lsmcli --help. To return to the installer, press Alt — F7.
A system analysis is performed, where the installer probes for storage devices, and tries to find other installed systems. If a network connection with Internet access is available, you will be asked to activate the online repositories. Answer with Yes to proceed. In case you do not have Internet access, this step will be skipped. The online repositories are official openSUSE package sources.
They not only offer additional packages not included on the installation media, but also the update repositories containing security and bug fixes. Using the default selection is recommended. Add at least the Main Update Repository , because it makes sure the system is installed with the latest security patches. Compared to the DVD installation media, it contains many additional software packages, among them many additional desktop systems.
Enabling these repositories is recommended for all installation scenarios. Enabling it is not required for installing a custom desktop system. This repository contains updates and security fixes for proprietary software. All other repositories are intended for experienced users and developers. Click on a repository name to get more information. Confirm your selection with Next. Depending on your choice, you need to confirm one or more license agreements. Do so by choosing Next until you proceed to the System Role screen.
Now choose Next to proceed. To simplify the installation, the installer offers predefined use cases which adjust the system to be installed so it is tailored for the selected scenario. Choose the System Role that meets your requirements best. The availability of system roles depends on your selection of modules and extensions. Therefore, the dialog is omitted under the following conditions:.
If from the enabled modules no role is suitable for the respective base product. In this case, the installation proceeds with the default settings for this product.
If from the enabled modules only one role is suitable for the respective base product. In this case, the installation proceeds with the settings of this particular role. A powerful desktop environment with a complete PIM suite mail, calendar, tasks, notes, and feeds , widgets running on the desktop and many more features.
If you are familiar with Windows, KDE is the recommended choice. A desktop environment offering an alternative, innovative user experience. GNOME was designed with usability and productivity in mind. A lightweight traditional desktop environment. You will be able to choose between the following alternatives later in the installation process by selecting Software in the Installation Settings dialog :. You can still enable this repository at later points during the installation by using the Back button until you reach the welcome screen.
From there, choose Next and then agree to add online repositories. If setting up a server, you probably do not need a graphical user interface and desktop applications such as an office suite. This option gives you a reduced set of packages suitable for servers. Similar to the server role, but with a read-only root partition and transactional updates. Read this section carefully before continuing with Section 3.
This partition must be formatted with the FAT32 file system. It needs to be formatted with the FAT32 file system. Btrfs needs to be set up with snapshots enabled for the root partition. If snapshots are enabled, the installer will automatically create single snapshots during and immediately after the installation. Snapshots occupy space on their partition. As a rule of thumb, the older a snapshot is, or the bigger the changeset they cover is, the bigger the snapshot.
Plus, the more snapshots you keep, the more disk space you need. The order of entries in lilo. This may happen after a certain interval, which can be set with the delay and timeout options as explained below.
Anything between a and the end of a line is regarded as a comment. Spaces and comments are ignored by LILO and can be used to improve readability. The entries in the above sample file include mandatory options and others that are explained in the list below:. The device on whose first sector LILO should be installed. If this option is missing, LILO is installed on the current root partition by default. Forces the LILO prompt to be displayed. The default is not to display any prompt.
This is recommended if LILO needs to manage more than one system. It should be used together with the timeout option to guarantee that the default system is automatically booted if nothing is entered at the prompt. Sets a time-out for selecting an operating system to boot.
The default system is booted after the time-out if there is no user input. The deciseconds value specifies the time-out in tenths of a second. The default time-out is set to In former Linux versions, this was a text file in which a description of the operating system name could be stored.
Current SuSE Linux versions use this file to load the splash screen. This specifies the name of the kernel image to boot, including its directory location. A name for the system in question e. Its maximum length is fifteen characters and it may only consist of letters, numbers, and underscores no blanks or special characters. For more about the specific characters that are allowed, see the LILO documentation. The default for this option is the file name of the corresponding kernel image e.
The same name is presented in the boot menu as one of the selectable items. One of the key points of UEFI is that it can be extended. UEFI has an internal virtual machine that is independent of the architecture that it is using. The standard accepts special binary files compiled for this virtual machine EFI binaries that can be executed inside the environment.
These binaries can be device drivers, applications or extensions to the UEFI standard. UEFI, in some sense, is like a small operating system that runs when the machine is powered on and whose main task is to find and load another operating system. How can you determine whether you have a UEFI machine?
Normally, check the firmware configuration pressing F1 or ESC , depending on the machine during the power on process. Browsing through the menus, it can be discovered that the machine can run in legacy mode the old BIOS mode , EFI mode and in a hybrid mode, where the actual model will be selected based on the operating system that will be loaded.
UEFI changes more things than the firmware, the syscalls and the interfaces. It also proposes a new style of partitioning the hard disk. MBR had some important limits, like the number of primary and logical partitions, and the size of these partitions. So, if you have have large disks, this is the kind of partition table that you would want. Another key difference is that GPT references every partition using an unique UUID number, avoiding collisions between partition identification. Once GPT partitions are in place, the old fdisk cannot be used anymore to create, remove or edit partitions.
The new tool to do that is gdisk and is in the gptfdisk package. The interface is the same one that we had in the fdisk tool. From time to time, if we are planning to make some test and experiment with the different modes, we will want to remove the GPT format from our hard disk. We can do that using YaST2. To do that go to the Expert Partitioner option , select the correct hard disk and in the "Expert Also, EFI will find here some device drivers used at boot time, and other tools needed to be run before the operating system is booted.
This partition uses a FAT file system and can be created via YaST2 during a fresh installation, or reused in a dual boot machine. In order to select the correct extension that will load the operating system, EFI provides to the user an internal boot manager. The operating system is responsible for creating a new entry for itself.
We can launch the boot manager, and list all the boot entries, during the power on process, usually pressing F9 or F But we can use the efibootmgr tool to query and edit the entries. For example, to list the current entries we can run efibootmgr -v. We can see that openSUSE created two different entries to boot. One is used when we are in secure mode, and the other when we are not.
If for some reason we lost one of the entries, we can recreate it using efibootmgr. For example, to recreate the entry 'opensuse' we can do:. The UEFI standard specify a set of variables that are stored in a non-volatile part in the firmware. Those variables are used to store information and to control the behavior of the UEFI system.
