RE: [Dev-C++] write a startup code

There is nothing magic about it.

All you have to do is setup the processor registers. Then you may call the
_main function and perform the rest of the hardware initialization there.

What type of processor are you using? If it is a 386 or higher you might
have to initialize processor to proper memory mappings and then enter
protected mode before calling _main.
