Installation guide

Another option is to perform a media check on your installation CD-ROMs. The Red Hat Enter-

prise Linux installation program has the ability to test the integrity of the installation media. It

works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. Red Hat recom-

mends that you test all installation media before starting the installation process, and before re-

porting any installation-related bugs (many of the bugs reported are actually due to improperly-

burned CDs). To use this test, type the following command at the boot: or yaboot: prompt

(prepend with elilo for Itanium systems):

linux mediacheck

2. Trouble Beginning the Installation

2.1. Problems with Booting into the Graphical Installation

There are some video cards that have trouble booting into the graphical installation program. If

the installation program does not run using its default settings, it tries to run in a lower resolution

mode. If that still fails, the installation program attempts to run in text mode.

One possible solution is to try using the resolution= boot option. This option may be most help-

ful for laptop users. Another solution to try is the driver= option to specify the driver that should

be loaded for your video card. If this works, it should be reported as a bug as the installer has

failed to autodetect your videocard. Refer to Chapter 8, Additional Boot Options for Intel and

AMD Systems for more information on boot options.

Note

To disable frame buffer support and allow the installation program to run in text

mode, try using the nofb boot option. This command may be necessary for access-

ibility with some screen reading hardware.

3. Trouble During the Installation

3.1. No devices found to install Red Hat Enterprise Linux Error Message

If you receive an error message stating No devices found to install Red Hat Enterprise

Linux, there is probably a SCSI controller that is not being recognized by the installation pro-

gram.

Check your hardware vendor's website to determine if a driver diskette image is available that

fixes your problem. For more general information on driver diskettes, refer to Chapter 7, Driver

Media for Intel and AMD Systems.
