Default 5 octave keyboard repair - tame musician required

For 5 octaves , for the "white" notes only , is the 15 th key from the left
middle C ? . Without any pitch-bend should it be 256 Hz or 256.?,262, 264 ?.
Or should the calibration be on "A" above middle C ie white key number 20 ?
and should that be exactly 440 Hz or some other frequency rounded to 440 Hz
?
