|  | <title>Introduction</title> | 
|  | <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. |
