Appendix E. Additional Boot Options

This appendix discusses additional boot and kernel boot options available for the Red Hat Enterprise Linux installation program.

Add these boot options to the parameter file. For more information, refer to Section 1.5 Installing under z/VM.

Boot Time Command Arguments


This command asks you to select the installation method you would like to use when booting from the Red Hat Enterprise Linux CD-ROM.


This argument causes the installation program to prompt you to use a driver image from a specified HTTP, FTP, or NFS network address.


This command allows 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 +remotehostname, where remotehostname is the name of the host from which you are running the original display. Using the command xhost +remotehostname limits access to the remote display terminal and does not allow access from anyone or any system not specifically authorized for remote access.


This command gives you the option of testing the integrity of the install source (if an ISO-based method). This command works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. Verifying that the ISO images are intact before you attempt an installation helps to avoid problems that are often encountered during an installation.


This command disables hardware detection and instead prompts the user for hardware information.


This command runs rescue mode. Refer to the Red Hat Enterprise Linux System Administration Guide for more information about rescue mode.


This command disables the graphical installation program and forces the installation program to run in text mode.


This command allows you to install from a VNC server.


This command sets the password used to connect to the VNC server.
