This folder contains the source for OS/K's early loader.
|
|
OS/K being intended to only run on x86-64 systems, we have not divided
|
|
this folder into one sub-folder per architecture.
|
|
|
|
The bootloader itself is external to the OS/K project. We are using GRUB 2 to
|
|
load our kernel loader in memory.
|
|
|
|
The kernel loader, that we call the loader, is the main subject of this folder.
|
|
This loader is linked whith the kernel and loaded by Grub at the specified
|
|
address and prepare it for the hard work it have to do :
|
|
|
|
- Check the multiboot state
|
|
- Check if CPUID and long mode is supported
|
|
- Send a structure for it with memory map, cpu infos, and other devices
|
|
infos, prepared by GRUB.
|
|
- Switch into long mode
