Hello,
I've already done a part of my OS in Assembly, but now I want to build a own bootloader for it too instead of using GRUB. When I was developing my test OS in Assembly I remember that I boot it like this:
This I've already know. Now I want to use this and execute the "real" OS that will be a *.bin file written to the 2nd sector of the floppy. Then I want to know somethings
Best Regards,

org 0x7c00
bits 16
; OS Kernel Here
times 510 - ($-$$) db 0
dw 0xAA55This I've already know. Now I want to use this and execute the "real" OS that will be a *.bin file written to the 2nd sector of the floppy. Then I want to know somethings
[*]How can I do a bootloader in Assembly to execute what will be starting on the 2nd sector of the floppy?
[*]I need to add anything to the Assembly source that will be placed on the 2nd sector of the floppy?
