4.4 Booting the Target System for Installation

Basically, there are two different ways to customize the boot process for installation apart from those mentioned under Section 4.3.7, Wake on LAN and Section 4.3.3, Using PXE Boot. You can either use the default boot options and function keys or use the boot options prompt of the installation boot screen to pass any boot options that the installation kernel might need on this particular hardware.

4.4.1 Using the Default Boot Options

The boot options are described in detail in Section 3.0, Installation with YaST. Generally, just selecting Installation starts the installation boot process.

If problems occur, use Installation—ACPI Disabled or Installation—Safe Settings. For more information about troubleshooting the installation process, refer to Section 51.2, Installation Problems.

4.4.2 Using the F Keys

The menu bar at the bottom screen offers some advanced functionality needed in some setups. Using the F keys, you can specify additional options to pass to the installation routines without having to know the detailed syntax of these parameters (see Section 4.4.3, Using Custom Boot Options).

See the table below for a complete set of the options available.

4.4.3 Using Custom Boot Options

Using the appropriate set of boot options helps facilitate your installation procedure. Many parameters can also be configured later using the linuxrc routines, but using the boot options is easier. In some automated setups, the boot options can be provided with initrd or an info file.

The following table lists all installation scenarios mentioned in this chapter with the required parameters for booting and the corresponding boot options. Just append all of them in the order they appear in this table to get one boot option string that is handed to the installation routines. For example (all in one line):

install=... netdevice=... hostip=...netmask=... vnc=... vncpassword=...
   

Replace all the values (...) in this string with the values appropriate for your setup.
