4.2. Kernel Bootstrap and Initialization
The boot process loads the binary kernel objects that make up the Solaris kernel from a bootable system disk into physical memory, initializes the kernel structures, sets system tuneable parameters, starts system processes (daemons), and brings the system to a known, usable state. The basic steps involved in booting can be summarized as follows:
The boot(1M) command reads and loads the bootblock into memory.
The bootblock locates and loads the secondary boot program, ufsboot, into memory and passes control to it.
ufsboot locates and loads the core kernel images and the required kernel runtime linker into memory and passes control to the loaded kernel.
The core kernel locates and loads mandatory ...
