Additional Boot Options
This section discusses additional boot and kernel boot options available for the Red Hat
Enterprise Linux installation program.
To use any of the boot options presented here, type the command you wish to invoke at the
installation boot: prompt.
boot time command arguments
askmethod
this command asks you to select the installation method you would like to use when booting
from the Red Hat Enterprise Linux CD-ROM.
dd=url
this argument causes the installation program to prompt you to use a driver image from a
specified HTTP, FTP, or NFS network address.
display=ip:0
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.
mediacheck
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.
noprobe
this command disables hardware detection and instead prompts the user for hardware
information.
rescue
this command runs rescue mode. Refer to Chapter 26, Basic System Recovery for more
information about rescue mode.
text
this command disables the graphical installation program and forces the installation
program to run in text mode.
