| 70 | <para> |
| 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. |
