- 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
