sinon oui il faut quand même écrire un bout de microkernel, et accroche toi le mec il fait ça en assembleur, oui mossieur

Boot image building
When JNode boots, the Grub bootload is used to load a Multiboot compliant kernel image and boot that image. It is the task of the BootImageBuilder to generate that kernel image.
The BootImageBuilder first loads java classes that are required to start JNode into there internal Class structures. These classes are resolved and the most important classes are compiled into native code.
The object-tree that results from this loading & compilation process is then written to an image in exactly the same layout as an object in memory is. This means that the the necessary heap headers, object headers and instance variables are all written in the correct sequence and byte-ordering.
The memory image of all of these objects is linked with the bootstrapper code containing the microkernel. Together they form a kernel image loaded & booted by Grub.
