Are You Unable to Boot from the CD-ROM?

If you cannot boot from your Red Hat Linux CD-ROM, you have two options:

	Note
	There are a few cases where the system BIOS will not allow the Red Hat Linux CD-ROM to boot because of the size of the boot image on the CD-ROM itself. In cases such as these, a boot disk should be made to boot Red Hat Linux. Once booted, the CD-ROMs will work properly for the installation.

1. You can change your BIOS so that booting from the CD-ROM is recognized first in the boot order, or

2. Boot using a boot disk you have created.

To change your BIOS, refer to your system manual for the correct keyboard combination that allows you to access your BIOS, or you can read the key sequence needed while the system begins to boot.

To create a boot disk, follow the instructions in the section called Making Installation Diskettes in Chapter 1.

To boot Red Hat Linux using a boot disk, insert the diskette you have created into your floppy drive and then boot/reboot your computer. Make sure that your BIOS is set to use the floppy or removable disk (A:) to boot.

Are You Unable to Boot from the Local Boot Disk?

If you are experiencing difficulties in getting a local boot disk to boot your system correctly, you may need an updated boot disk.

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.
