I’m looking for feedback and what I should add to my Minimal x86 Bootloader that I made in Assembly.

It’s very small and limited and I’m looking for suggestions to add.

Here is the code:

; Simple boot sector
; Assembled with NASM
; nasm -f bin boot.asm -o boot.bin

org 0x7C00
bits 16

start:
    mov si, message

print_loop:
    lodsb              ; AL = [SI], SI++
    cmp al, 0
    je hang
    mov ah, 0x0E       ; BIOS teletype output
    int 0x10
    jmp print_loop

hang:
    cli
    hlt
    jmp hang

message db "Hello from bare metal!", 0

times 510-($-$$) db 0
dw 0xAA55

Thank you have a good day : D
