I'll give you a list:
  1. Standardized mode numbers are deprecated and should not be used.
  2. You are calling a real mode interrupt from inside protected mode (GRUB puts you in pmode)
    • If you are using v8086, it should work, but based on your question, I don't think you know how

Self-explanatory
