QCONFIG - Recognized Machines

Information extracted from the QCONFIG executable (PC DOS J7.0/V update C) by Major Tom.

Please note that the list below represents the static data stored in the QCONFIG binary. Some of this data is not used as-is and additional processing/on-the-fly checks are done by the QCONFIG code to pinpoint a particular machine, CPU, and slot configuration more accurately.

The Unk. column is used only as a part of the mouse detection code (checked against 500h) and a couple of other places (always checked against 0). The exact meaning of this data is currently unknown. Almost all PS/2 and PS/55 machines are ≥ 500h except for Models 25 386SX & 30 386SX (why?). If you have any clue what these values mean, let us know.
