During the KEMP LoadMaster bare metal installation, a number of boot options are available such as running a compatibility check and/or selecting the disk/partition.

1.1Document Purpose

This document provides further information on each of the bare metal boot options.

1.2Intended Audience

This document is intended to be read by anyone who needs to find out further information about the KEMP LoadMaster bare metal boot options.

2Boot Options

Figure 2‑1: Boot menu

During the bare metal installation, there is a pause which allows you to specify the boot parameters. A number of boot options are available:

  • install - Start the installation with no boot parameters. This is the default boot option and will be executed if no boot parameters are entered.
  • acpinoirq - Boot with acpi=noirq. This disables PCI Interrupt Request (IRQ) routing in Advanced Configuration and Power Interface (ACPI).
  • acpino - Boot with acpi=no. This disables ACPI.
  • pcibiosirq - Boot with pci=biosirq. This uses PCI BIOS calls to get the interrupt routing table.

To specify the desired boot option, type the parameter value as outlined in bold in the points above. If a boot parameter is mistyped, an error will be displayed.

When one of the above boot parameters are specified, the settings will be applied to the LoadMaster Operating System (OS).
