    The subaddressing extension is not the only way the reach of POS can be extended, however. The Micro Channel design also allows the use of two special set-up files to adjust and initialize expansion board functions
    in ways that POS by itself cannot handle. These special files are
    discussed in the next chapter.

    Louis, can you link me to the next chapter??

    I somehow gained two copies over the years (it would be cool to get autographs on both now) - but it isn't too bad at under $40:

    MCAH is on Internet Archive, unfortunately not freely downloadable. I
    sign in, "borrow" it, then do screen caps of each page. MAJ Tom OCRs it,
    then I HTMLize it.

    Note: The MCAH has a goodly part ad rush, pre-90 facts, and stuff from published MCA references. For instance, the subaddressing stuff can be
    found in the HITR. Also, there are inaccuracies. WBST pointed out that
    at least one section that I quoted was wrong.

    The "strength" of the MCAH is the scattered nuggets of well written, or re-written, MCA functions. I had considered more HTMLizing, but there
    isn't enough stuff in it that wouldn't require extensive commenting to
    bring out the significance of the text.

    I have no problem buying the book, but does it really cover XPOS and initialization programs?? Does it have any sample code or break down how to compile an initialization program in C?

    I don't believe a "setup cycle" can happen once DOS is loaded. Doesn't seem like CDSETUP is going high. INP and OUT with QBasic gets no reaction from the 8F62 card.

    Unless Peter lets us know the source of the initialization ADF programs documentation that's on his website on how to write these programs I'm out of ideas.

    Whole lotta details. Was the bridge chip enabled? I think the XPOS is on it.

    I followed the flow chart. Of course you can get POS values back all day long. Card does not respond to XPOS, never gives me back any values in Pos reg 4.

    In the past POS reads from AIX, POS 5 is 0xFF

    Not mentioned in the patent doc.
