Starting Kernel from Bootsector

Post by ollie123 »

I'm back with another question. How can I start my kernel from my bootsector? Do I need to manipulate the memory in any way? Is there code that I can add to my bootsector to start my kernel directly? I would appreciate a response.

Thanks,
Ollie :D.

PS: I'm sorry if I keep posting questions like this. I have only just started programming operating systems, and I keep running into bugs.

Assuming that you have at least followed the many tutorials around, what about them do you not understand?

Try one. If it doesn't help go to the next and so on. Nine out of ten you'll have your answer before you see the end of the list :D

Are you planning on working in real or protected mode?

I think nobody here can claimed to have got very far in their OS before encountering a bug (certainly not me...). Its not meant to be easy...

I would use GRUB, but I still want to learn how to write bootsectors.

If you can write some assembly, try to write your own simple bootloader. Its an excellent practice. My own bootloader is near complete.
