- <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.
