The Boot Screen

The boot screen displays a number of options for the installation procedure. Boot from Hard Disk boots the installed system and is selected default, because the CD/DVD is often left in the drive. To install the system, select one of the installation options with the arrow keys. The relevant options are:

Installation

The normal installation mode. All modern hardware functions are enabled. All modern hardware functions are enabled.

Installation—ACPI Disabled

If the normal installation fails, this might be due to the system hardware not supporting ACPI (advanced configuration and power interface). If this seems to be the case, use this option to install without ACPI support.

Installation—Local APIC Disabled

If the normal installation fails, this might be due to the system hardware not supporting local APIC (Advanced Programmable Interrupt Controllers). If this seems to be the case, use this option to install without local APIC support.

If you are not sure, try one of the following options first: Installation—ACPI Disabled or Installation—Safe Settings.

Installation—Safe Settings

Boots the system with the DMA mode (for CD-ROM drives) and power management functions disabled.

Rescue System

Starts a minimal Linux system without a graphical user interface. For more information, see Section 46.6.3.2, “Using the Rescue System”.

Memory Test

Tests your system RAM using repeated read and write cycles. Terminate the test by rebooting. For more information, see Section 46.2.5, “Fails to Boot”.

Installation options from the menu disable only the most problematic functions. If you need to disable or set other functions, use the Boot Options prompt. Find detailed information about kernel parameters at http://en.opensuse.org/Linuxrc.

Use the function keys indicated in the bar at the bottom of the screen to change the language, resolution of the monitor, or installation source or to add an additional driver from your hardware vendor:

F1 Help: Get context-sensitive help for the active element of the boot screen.
F2 Language: Select the display language for the installation. The default language is English.
F3 Other Options: Enables further options that can be set for installation.

After you press F3, additional options can be set:

F3 Video Mode: Select various graphical display modes for the installation. Select Text Mode if the graphical installation causes problems.
F4 Source: Normally, the installation is performed from the inserted installation medium. Here, select other sources, like FTP or NFS servers. If the installation is carried out in a network with an SLP server, select one of the installation sources available on the server with this option. Find information about SLP in Chapter 31, SLP Services in the Network.
F5 Driver: Press this key to tell the system that you have an optional disk with a driver update for SUSE Linux Enterprise. With File, load drivers directly from CD before the installation starts. If you select Yes, you are prompted to insert the update disk at the appropriate point in the installation process. The default option is No—not to load a driver update.

After starting the installation, SUSE Linux Enterprise loads and configures a minimal Linux system to run the installation procedure. To view the boot messages and copyright notices during this process, press Esc. On completion of this process, the YaST installation program starts and displays the graphical installer.

	Installation without a Mouse
If the installer does not detect your mouse correctly, use Tab for navigation, arrow keys to scroll, and Enter to confirm a selection.

Providing Data to Access a SMT Server

If your network provides a SMT server to provide a local update source, you need to equip the client with the server's URL. Client and server communicate solely via HTTPS protocol, therefore you also need to enter a path to the server's certificate if the certificate was not issued by a certificate authority. This information has to be entered at the boot prompt.

smturl

URL of the SMT server. The URL has a fixed format https://FQN/center/regsvc/ FQN has to be full qualified hostname of the SMT server. Example:

smturl=https://smt.example.com/center/regsvc/

smtcert

Location of the SMT server's certificate. Specify one of the following locations:

URL

Remote location (http, https or ftp) from which the certificate can be downloaded. Example:

smtcert=http://smt.example.com/smt-ca.crt

Floppy

Specifies a location on a floppy. The floppy has to be inserted at boot time, you will not be prompted to insert it if it is missing. The value has to start with the string floppy followed by the path to the certificate. Example:

smtcert=floppy/smt/smt-ca.crt

local path

Absolute path to the certificate on the local machine. Example:

smtcert=/data/inst/smt/smt-ca.cert

Interactive

Use ask to open a pop-up menu during the installation where you can specify the path to the certificate. Do not use this option with AutoYaST. Example

smtcert=ask

Deactivate certificate installation

Use done if either the certificate will be installed by an add-on product, or if you are using a certificate issued by an official certificate authority. Example:

smtcert=done

Beware of typing errors

	Beware of typing errors
Make sure the values you enter are correct. If `smturl` has not been specified correctly, the registration of the update source will fail. If a wrong value for smtcert has been entered, you will be prompted for a local path to the certificate. In case smtcert is not specified, it will default to `http://FQN/smt.crt` with `FQN` being the name of the SMT server.
