Operating system development-the simplest bootsect (you can add code directly to it)

ORG 0x7c00; load this program to 0X7C00, because the BIOS will default from memory 0x7c00 to execute JMP os_entry[bits 16]os_entry:        //Here Add code times 510-($-$$) DB 0; Fill the remaining space so that the generated binary code is exactly 512 bytes db 0X55,0XAA; BIOS-approved End flag

That's what the code says, and the comments are clear. You can contact me if you have any other areas that you don't understand.

If you have any questions, you can contact me: email:[email protected]

If the reader friend also has the idea of developing the operating system, you can contact me.
