The Red Hat Enterprise Linux installation system includes a range of functions and options for administrators. To use boot options, enter
linux at the
If you specify more than one option, separate each of the options by a single space. For example:
28.1. Configuring the Installation System at the Boot Menu
You can use the boot menu to specify a number of settings for the installation system, including:
28.1.1. Specifying the Language
To set the language for both the installation process and the final system, specify the ISO code for that language with the
lang option. Use the
keymap option to configure the correct keyboard layout.
For example, the ISO codes
gr identify the Greek language and the Greek keyboard layout:
28.1.2. Configuring the Interface
To use a specific display resolution, enter
resolution= as a boot option. For example, to set the display resolution to 1024×768, enter:
To run the installation process in
To enable support for a
serial console, enter
as an additional option.
display= to allow remote display forwarding. In this command,
ip should be replaced with the IP address of the system on which you want the display to appear.
On the system you want the display to appear on, you must execute the command
xhost +, where
remotehostname is the name of the host from which you are running the original display. Using the command
xhost + limits access to the remote display terminal and does not allow access from anyone or any system not specifically authorized for remote access.
28.1.3. Updating anaconda
You can install Red Hat Enterprise Linux with a newer version of the anaconda installation program than the one supplied on your installation media.
The boot option
presents you with a prompt that asks you for a disk image containing anaconda updates. You do not need to specify this option if you are performing a network installation and have already placed the updates image contents in
rhupdates/ on the server.
To load the anaconda updates from a network location instead, use:
followed by the URL for the location where the updates are stored.
28.1.4. Specifying the Installation Method
askmethod option to display additional menus that enable you to specify the installation method and network settings. You may also configure the installation method and network settings at the
boot: prompt itself.

28.1.5. Manually Configuring the Network Settings
By default, the installation system uses DHCP to automatically obtain the correct network settings. To manually configure the network settings yourself, either enter them in the Configure TCP/IP screen, or at the
boot: prompt. You may specify the
dns server settings for the installation system at the prompt. If you specify the network configuration at the
boot: prompt, these settings are used for the installation process, and the Configure TCP/IP screen does not appear.
This example configures the network settings for an installation system that uses the IP address
