### Interaction between Bootloader and Kernel

The bootloader locates the Multiboot2 header within the ELF file.
After verifying the magic number and architecture compatibility, it parses the header and tags to gather essential system information.
It then loads the kernel into memory, sets up the environment, and transfers control to the kernel's entry point.
After verifying the magic number and architecture compatibility, it parses the header and tags.
Next, the information requested by the tags is placed into the kernel memory and the bootloader passes control to the kernel.

The kernel, in turn, accesses the Multiboot2 header using the information provided by the bootloader.
It iterated through the tags to extract the necessary data, such as memory regions, boot command line, and other parameters.
