Got the bootloader to load kernel.c which is empty but you can see in the gdb log in the terminal that it does load void kernel_main. Next I am going to rewrite the bootloader into a two stage bootloader so it can have a print routine, retrying disk reads, A20 handling and an E820 memory map. Since all of this isnt possible in just 510 bytes (last two bytes reserved for the boot sector signature being 0x55 and 0xAA) I will split it into two stages.
