D Troubleshooting Your Installation of
Red Hat Linux
This appendix discusses some common installation problems and their solutions.
D.1 You are Unable to Boot Red Hat Linux
D.1.1 Is Your System Displaying Signal 11 Errors?
If you receive a fatal signal 11 during your installation, it is probably due to a hardware error in memory
on your system’s bus. A hardware error in memory can be caused by problems in executables or with
the system’s hardware. Like other operating systems, Red Hat Linux places its own demands on your
system’s hardware. Some of this hardware may not be able to meet those demands, even if they work
properly under another OS.
Check to see if you have the latest installation and supplemental boot diskettes from Red Hat. Review
the online errata to see if newer versions are available. If the latest images still fail, it may be due
to a problem with your hardware. Commonly, these errors are in your memory or CPU-cache. A
possible solution for this error is turning off the CPU-cache in the BIOS. You could also try to swap
your memory around in the motherboard slots to see if the problem is either slot or memory related.
For more information concerning signal 11 errors, refer to http://www.bitwizard.nl/sig11/.
D.1.2 Are You Unable to Boot from a Network Boot Disk?
If you are experiencing difficulties in getting the network boot disk you made to boot your system
correctly, you may need an updated boot disk.
Check the online errata for updated diskette images (if available) and follow the instructions provided
to make an updated boot disk for your system.
D.2 Trouble Beginning the Installation
D.2.1 Is Your Mouse Not Detected?
If the Mouse Not Detected screen (see Figure D–1, Mouse Not Detected) appears, then the installation
program was not able to identify your mouse correctly.
You can choose to continue with the GUI installation or use the text mode installation, which does
not require using a mouse. If you choose to continue with the GUI installation, you will need to
provide the installation program with your mouse configuration information (see Figure 3–3, Mouse
Configuration).
