Interruption 16h - Keyboard BIOS Services - WIP

  • with IBM BIOS's, INT 16 functions do not restore the flags to the pre-interrupt state to allow returning of information via the flags register
  • functions 3 through 12h are not available on all AT machines unless the extended keyboard BIOS is present
  • all registers are preserved except AX and FLAGS
