In order to shutdown the system, you need to use the APM/ACPI (preferably calling the BIOS). There should be code for that in The Mobius.

Using INT15h (according to Tim's code which appears to be Menuet code)

  • disconnect interface (ax=5304, bx=0)
  • connect real mode interface (ax=5301,bx=0)
  • enable power management (ax=5308, cx=bx=1)
  • enable device power management(ax=530D, cx=bx=1)
  • engage power management (ax=530f,cx=bx=1)
  • driver version (ax=530E, bx=0, cx=102)
  • set power state(ax=5307, bx=1, cx=3)
