Creating bootable image for VirtualBox

问题

I need just welcome message printed.

There are some hints on this forum, however it's hard to put all up together.

So I've created a mininmal .asm similar to this one

[ORG 0x7c00] 
BITS 16

main:
mov ax, 0x07C0
mov ds, ax
mov es, ax

mov bp, message
mov bh, 0
mov bl, 00001111b

mov cx, 13
mov al, 1

mov ah, 0x13
mov dx, 0
int 0x10

cli
hlt

jmp $

message db "Hello, World!"
length db (length - message)

times 510-($-$$) db 0
dw 0xaa55

Build:

nasm -f bin sboot.asm -o sboot.bin
dd if=sboot.bin of=sboot.img bs=512 count=1 conv=notrunc

And convert IMG file to ISO with program CDBurnerXP. I am using 'Boot options...' and select:

  • Emulation type = Diskette 1.44MB (boot image 95/98/ME)
  • Load segment = 7c0
  • Sectors: 1
  • Platform: x86-64
    I also add dummy txt file, so that the ISO is not empty and save everything as ISO file.

Then I try to run it in Virtual Box with minimum options (disabled: audio, network, USB) and it crashes. Container goes into status 'Aborted'

Log from VirtualBox says nothing particular:

Any idea what went wrong?

Your setup for DS and ES does not match the ORG setting!

If you use [ORG 0x7c00], then you have to set DS=0 and ES=0.
Since you only use the BIOS function 13h that depends on ES:BP, setting up ES would be enough:

xor ax, ax
mov es, ax
