- 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
