-Bootloading is the name of the process for starting up the system, in particular loading the kernel code, also called kernel image, into RAM memory.

-Summary of the boot process:

-- <http://www.ibm.com/developerworks/library/l-linuxboot/>
-- <http://www.thegeekstuff.com/2011/02/linux-boot-process/>
-
-The first thing the computer does is to run fixed code from the BIOS.
-
-It tries to find all the devices all devices that can contain a kernel image like: hard disk, CD/DVD, flash drives, floppies.
-
-It searches for the Master Boot Record (MBR).
-
-In normal desktop operation, the hard disk is the main MBR source, but when you install your OS, you load it from either a CD / DVD or USB stick.
-
-The search order is deterministic and configurable. Typically the first and default option is the hard disk.
-
-The first splash screen shown to the users comes from this process.
-
-If you are quick enough on you keyboard, you can stop the default boot, and manually chose another boot source.
-
-This way you can tell your BIOS to take a live CD or USB even if the OS is installed on the hard disk.
-
-## Second stage bootloader
-
-The 512B of the MBR is a too little space for having a flexible boot system.
-
-The MBR points to a second stage bootloader in its disk which which will do the actual booting.
-
-The most popular second stage bootloader for Linux now is GRUB. LILO was a popular alternative in the past. Windows has its own bootloader.
+First you must understand the non-Linux-specifics with minimal examples: <https://github.com/cirosantilli/x86-bare-metal-examples>

 - `config-VERSION`: the kernel configuration options, generated at configuration before kernel compilation by `make menuconfig`
 - `abi-VERSION`: TODO what is? Looks like the kernel symbol table of exported symbols.
