I dont have the source at hand now. But if the firmware/init/main.c is
running you are already in protected mode with all
32bit mechanisms running. Here you are in a state where you can ignore the
bootsect.S and even the setup.S of the kernel.
just try to read the kernel off your disk with plain ATA commands and then
jump to the adress of the a symbol called "start_kernel" or something like
