Appendix D. Troubleshooting Your Installation of Red Hat Linux

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.1.4. Is Your System Displaying Signal 11 Errors?

If you receive a fatal signal 11 error 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.

D.1.5. 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. Trouble Using PCMCIA Boot Disks?

If you booted using PCMCIA boot disks and want to install via FTP (or NFS or HTTP), but do not

see these installation options, you may have a problem with your network card.

If the network card is not initialized during the boot process, the Red Hat Linux installation program

will not enable you to configure your system for networking, either during or after the installation

itself.

Check the hardware compatibility list at

http://hardware.redhat.com/hcl/

to see if your network card is compatible and/or supported. If your card is not listed, it may not be

compatible with Red Hat Linux.

D.2.2. Is Your Mouse Not Detected?

If the Mouse Not Detected screen (see Figure D 1) appears, then the installation program was not

able to identify your mouse correctly.
