This section includes information about boot processes that are unique to booting an x86 based system.
When an x86 based system is powered on, it is controlled by the read-only-memory (ROM) Basic Input/Output System (BIOS). The BIOS is the firmware interface on Oracle Solaris operating systems that have x86 64-bit and 32-bit support.
Hardware adapters usually have an on-board BIOS that displays the physical characteristics of the device. The BIOS is used to access the device. During the startup process, the system BIOS checks for the presence of any adapter BIOS. If any adapters are found, the system then loads and executes each adapter BIOS. Each adapter's BIOS runs self-test diagnostics and then displays device information.
The BIOS on most systems has a user interface, where you can select an ordered list of boot devices that consists of the following selections:
Diskette
CD or DVD
Hard disk
Network
The BIOS attempts to boot from each device, in turn, until a valid device with a bootable program is found.
The /platform/i86pc/multiboot program is an ELF32 executable that contains a header which is defined in the Multiboot Specification.
The multiboot program is responsible for performing the following tasks:
Interpreting the content of boot archive
Autodetection of systems that are 64-bit capable
Selecting the best kernel mode for booting the system
Assembling core kernel modules in memory
Handing control of the system to the Solaris kernel
After the kernel gains control of the system, the kernel initializes the CPU, memory, and device subsystems. The kernel then mounts the root device, which corresponds to the bootpath and fstype properties that are specified in the /boot/solaris/bootenv.rc file. This file is part of the boot archive. If these properties are not specified in the bootenv.rc file, or on the GRUB command line, the root file system defaults to UFS on /devices/ramdisk:a. The root file system defaults to UFS when you boot the installation miniroot. After the root device is mounted, the kernel initializes the sched and init commands. These commands start the Service Management Facility (SMF) services.
