System Start-Up for Installation

You can install SUSE Linux Enterprise from local installation sources, such as the SUSE Linux Enterprise CDs or DVD, or from the network source of an FTP, HTTP, SLP, or NFS server. Any of these approaches requires physical access to the system to install and user interaction during the installation. The installation procedure is basically the same regardless of the installation source.

Boot Options

Boot options other than CD or DVD exist and can be used if problems arise booting from CD or DVD. These options are described in Table 3.1, “Boot Options”.

Table 3.1. Boot Options

Boot Option	Description
DVD/CD-ROM	This is the easiest boot option. This option can be used if the system has a local CD/DVD-ROM drive that is supported by Linux.
Floppy	The images for generating boot floppies are located on CD/DVD 1 in the `/boot` directory. A `README` is available in the same directory.
PXE or BOOTP	This must be supported by the system's BIOS or firmware and a boot server must be available in the network. This task can also be handled by another SUSE Linux Enterprise system.
Hard Disk	SUSE Linux Enterprise can also be booted from the hard disk. To do this, copy the kernel (`linux`) and the installation system (`initrd`) from the directory `/boot/loader` on CD/DVD 1 to the hard disk and add the appropriate entry to the boot loader.

Installing from the SUSE Linux Enterprise Media

To install from the media, insert the first CD or DVD into the appropriate drive of the system to install. Reboot the system to boot from the media and open the boot screen.

Installing from a Network Server Using SLP

If your network setup supports OpenSLP and your network installation source has been configured to announce itself via OpenSLP (described in Section 4.2, “Setting Up the Server Holding the Installation Sources”), boot the system from the media or with another boot option. In the boot screen, select the desired installation option. Press F4 then select SLP.

The installation program retrieves the location of the network installation source using OpenSLP and configures the network connection with DHCP. If the DHCP network configuration fails, you are prompted to enter the appropriate parameters manually. The installation then proceeds as described below.

Installing from a Network Source without SLP

If your network setup does not support OpenSLP for the retrieval of network installation sources, boot the system from the media or with another boot option. In the boot screen, select the desired installation option. Press F4 then select the desired network protocol (NFS, HTTP, FTP, or SMB). Provide the server's address and the path to the installation media.
