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