 Actually this is the first code that runs (aside from the previous jump instruction of course). After the kernel setup got the control from the bootloader, the first `jmp` instruction is located at `0x200` (first 512 bytes) offset from the start of the kernel real mode. This we can read in the Linux kernel boot protocol and also see in the grub2 source code:
 
 ```C
+segment = grub_linux_real_target >> 4;
 state.gs = state.fs = state.es = state.ds = state.ss = segment;
 state.cs = segment + 0x20;
