<title>Introduction</title>

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.
