<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.
