70  <para>
71	The MCA bus functions provide a generalised interface to find MCA
72	bus cards, to claim them for a driver, and to read and manipulate POS 
73	registers without being aware of the motherboard internals or 
74	certain deep magic specific to onboard devices.
75  </para>
76  <para>
77	The basic interface to the MCA bus devices is the slot. Each slot
78	is numbered and virtual slot numbers are assigned to the internal
79	devices. Using a pci_dev as other busses do does not really make
80	sense in the MCA context as the MCA bus resources require card
81	specific interpretation.
82  </para>
83  <para>
84	Finally the MCA bus functions provide a parallel set of DMA
85	functions mimicing the ISA bus DMA functions as closely as possible,
86	although also supporting the additional DMA functionality on the
87	MCA bus controllers.
