 |   <para> | 
 | 	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. |
