Installation Procedures
12 RedHawk Linux Version 5.4 Release Notes
5.0. Installation Procedures
Review the following points before installing the software:
• Concurrent recommends these procedures be followed as documented here; however,
advanced users may decide to make other choices based on onsite requirements.
• The installation media in use is accessed at various times and must be kept in the drive
during the installation until you are instructed to install different media.
• Prior to installation, remove any floppy media that may have been left in the machine.
Before you start:
• Main Memory Size — You need to know the system’s main memory size in order to
properly set up the file system swap size. If you are not sure of the main memory size,
access the system’s BIOS to ascertain this information.
• Network Addresses — If you do not plan to configure networking DHCP, you will
need to have the following information for your system before beginning the
installation:
- IP address - gateway address
- netmask address - primary and secondary DNS addresses
• BIOS Settings — BIOS settings should be reviewed before installation and whenever
problems involving non-working devices are encountered. Exercise caution before
changing default settings. Concurrent makes the following recommendations:
- “Linux” should be specified for the “Installed OS” setting (or its equivalent) if it is an available
option. If not, use the default “other.”
- Only the default settings for memory functions and PCI timing functions are supported.
- ACPI support should be enabled, but care should be taken before changing other ACPI options
from their defaults. ACPI sleep states should not be enabled in the BIOS or in any custom
kernel build.
- Ensure that the drive to be used for installations and updates is bootable and that the boot order
is correctly set in the BIOS so that you will boot to the anaconda installer instead of from disc.
5.1 Installing Red Hat Software
The version of Red Hat Enterprise Linux that is appropriate to your system’s architecture must
be installed on the system first by specifically completing the steps below. Installation of Red
Hat is accomplished in two parts:
