x86: Boot ProcessesThis section includes information about boot processes that are unique to booting an x86 based system. x86: System BIOSWhen a system is powered on, the system is controlled by the read-only-memory (ROM) Basic Input/Output System (BIOS). The BIOS is the firmware interface on 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:
The BIOS attempts to boot from each device, in turn, until a valid device with a bootable program is found. x86: Kernel Initialization ProcessThe /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:
