Red Hat Linux Installation

This section provides information to help you resolve issues that may occur
during installation of Red Hat Linux 9. Following is a list of conditions and
possible solutions.
Topic
Your system will not
boot from the Red Hat
Linux CD.
Your system is
displaying Signal 11
Error. A Signal 11
error (segmentation
fault) means that the
program accessed a
memory location that
was not assigned.
Solution
• Some older SCSI devices do not tolerate Domain
Validation operations, which is a feature of Ultra320
SCSI. At boot time, the system performs Domain
Validation to test the data integrity of the SCSI bus
between the host adapter and each target device.
With some older SCSI devices, these operations
can cause the device to stop responding to SCSI
commands.
• First check all internal and external SCSI bus cable
connections. If the problem continues, disable
Domain Validation for a specific SCSI device by
using the Fusion-MPT SCSI BIOS Configuration
Utility to set the Sync Rate to 0 (async) and the
Data Width to 8. This target will be running in
async/narrow mode and no Domain Validation
operations will be performed on it.
Solution
• Change the BIOS boot order so that booting from
the CD is recognized first.
• Create and use a boot diskette to boot from.
1
Check to see if you have the latest installation and
supplemental boot diskettes from Red Hat.
2
Turn off the CPU-cache in the BIOS.
3
Check your system memory.
4
Try running the installation with 64MB of memory.
Do this by booting the installation program with
the mem-64M boot option. At the installation boot
prompt, type: boot: mem=64M
5
Check your memory (RAM) with the cat
/proc/meminfo command
6
Preform a media check on your installation CDs. To
test the checksum integrity of an ISO image, at the
installation boot prompt, type:
boot: linux mediacheck
