 # Kernel initialization process
 
-You will find here a couple of posts which describe the full cycle of kernel initialization from its first steps after the kernel has decompressed to the start of the first process run by the kernel itself.

-*Note* That there will not be description of the all kernel initialization steps. Here will be only generic kernel part, without interrupts handling, ACPI, and many other parts. All parts which I'll miss, will be described in other chapters.

 * [First steps after kernel decompression](https://github.com/0xAX/linux-insides/blob/master/Initialization/linux-initialization-1.md) - describes first steps in the kernel.
 * [Early interrupt and exception handling](https://github.com/0xAX/linux-insides/blob/master/Initialization/linux-initialization-2.md) - describes early interrupts initialization and early page fault handler.
