Most of the information presented here was taken from the following manual:

IBM Personal System /2 Hardware Interface Reference Manual - Architectures, 1st Ed., Oct 1990

The manual includes additional info about ADPs and Initialization programs that was missing from the earlier releases.

Further information was obtained by reading through several hundred different ADFs and studying their content.
