 ### Summary
 Stage 1 loader loads stage 2 loader from the floppy and jumps to it.
 
-Stage 2 loader initializes protected mode, detects system memory, loads the kernel from the floppy, and eventually calls "kmain" function in kernel.c.
+Stage 2 loader initializes protected mode, detects system memory, loads stage 3 and kernel from the floppy and jumps to stage 3.
+
+Stage 3 is supposed perform initialization in protected mode. It should be called stage 2.5 because it's the same thing but 32 bit binary, it reloads GDT to predictable range,  initializes IDT, tests #DIV exception and and eventually jumps to kernel.
+
+The kernel prints a welcome message and loops infinitely.
 
 Yes the ASM code and the makefile could use some refactoring. Yes I know floor can be calculated simply by (x + y - 1) / y.
