This folder contains the source for OS/K's early loader.
|
2018-12-20 18:03:39 +01:00
|
|
|
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.
