<chapter id="intro">
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.
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.
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.
