Chapter 6. Troubleshooting <strong>Installation</strong> on an Intel® or AMD System<br />

It works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. <strong>Red</strong> <strong>Hat</strong><br />

re<strong>com</strong>mends that you test all installation media before starting the installation process, and<br />

before reporting any installation-related bugs (many of the bugs reported are actually due to<br />

improperly-burned CDs). To use this test, type the following <strong>com</strong>mand at the boot: or yaboot:<br />

prompt (prepend with elilo for Itanium systems):<br />

<strong>linux</strong> mediacheck<br />

2. Trouble Beginning the <strong>Installation</strong><br />

2.1. Problems with Booting into the Graphical <strong>Installation</strong><br />

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

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

mode. If that still fails, the installation program attempts to run in text mode.<br />

One possible solution is to try using the resolution= boot option. This option may be most<br />

helpful for laptop users. Another solution to try is the driver= option to specify the driver that<br />

should be loaded for your video card. If this works, it should be reported as a bug as the<br />

installer has failed to autodetect your videocard. Refer to Chapter 8, Additional Boot Options for<br />

Intel® and AMD Systems for more information on boot options.<br />

Note<br />

To disable frame buffer support and allow the installation program to run in text<br />

mode, try using the nofb boot option. This <strong>com</strong>mand may be necessary for<br />

accessibility with some screen reading hardware.<br />

3. Trouble During the <strong>Installation</strong><br />

3.1. No devices found to install <strong>Red</strong> <strong>Hat</strong> <strong>Enterprise</strong> <strong>Linux</strong> Error Message<br />

If you receive an error message stating No devices found to install <strong>Red</strong> <strong>Hat</strong> <strong>Enterprise</strong><br />

<strong>Linux</strong>, there is probably a SCSI controller that is not being recognized by the installation<br />

program.<br />

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