My own OS - How to start?

Hi Community. I want to develop my own OS. It should have an easy bootloader which loads my kernel. The kernel should initialize the keyboard and print a console on the screen. There i would like to type in commands. and a programm, which is in an other file should start. after typing somthing, maybe exit. The startes Programm should shutdown and the console should be shown again.
But I think it's to much for the beginning. I first need a bootloader, a console and a kernel with keyboard support. Everything should be written in Assembler.
My Question: Do I need more? Can you give me some tips and tutorials?

Thanks

for boot loaders, i would spend a while writing your own boot sector - it feels so good to put "Hello world"in video memory. After you are confident making bios interrupt calls and displaying directly in video memory, i would seriously recommend you use GRUB as your boot loader at least until your kernel actually is a kernel (can manage memory and do some basic scheduling) if you want to you can then go back and write your own boot sector & loader.
