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