 Ha Windowsos gépekről is szeretnél kernelt küldeni, akkor javaslom inkább a John Cronin féle átiratot, a
 [raspbootin-server](https://github.com/jncronin/rpi-boot/blob/master/raspbootin-server.c)-t, ami natív Win32 API-t használ.

 This tutorial is a rewrite of the well known serial boot loader, [raspbootin](https://github.com/mrvn/raspbootin) in 64 bit.
 I only provide one part of the loader, the kernel receiver, which runs on the RPi. For the other

 If you want to send kernels from a Windows machine, I suggest to take a look at John Cronin's rewrite,
 [raspbootin-server](https://github.com/jncronin/rpi-boot/blob/master/raspbootin-server.c) which can be compiled for the Win32 API.
