This chapter describes linux kernel booting process. You will see here a couple of posts which describes full cycle of the kernel loading:

• From the bootloader to kernel - describes all stages from turning on the computer before the first instruction of the kernel;
• First steps in the kernel setup code - describes first steps in the kernel setup code. You will see heap initialization, querying of different parameters like EDD, IST and etc...
• Video mode initialization and transition to protected mode - describes video mode initialization in the kernel setup code and transition to protected mode.
• Transition to 64-bit mode - describes preparation for transition into 64-bit mode and transition into it.
• Kernel Decompression - describes preparation before kernel decompression and directly decompression.
