Overview of the Oracle Solaris Boot Architecture

The Oracle Solaris boot architecture includes the following fundamental characteristics:

How the x86 Boot Process Works

This section describes the basic boot process on Oracle Solaris x86 platforms. For more information about boot processes on specific hardware types, including systems that have service processors and systems that have multiple physical domains, see the product documentation for your specific hardware at

When an x86 based system is powered on, the BIOS initializes the CPU, the memory, and the platform hardware. When the BIOS phase completes, the boot loader is loaded from the configured boot device and control of the system is transferred to the boot loader, which in turn starts the boot process. The boot loader is the first software program that runs after you turn on a system. This program starts the boot process. In Oracle Solaris the GRand Unified Bootloader, otherwise known as "GRUB", is the default boot loader on x86 based systems.
