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.
