* All of the stub routines required for backwards compatibilty with the
|
|
* Slot Manager for systems without a NuBus.
|
|
*
|
|
* These routines field all the Nubus slot manager requests, forwarding
|
|
* them to code installed dynamically for xxBus <-> NuBus bridges.
|
|
*
|
|
* Any 'Slot Manager Compatibility Layer' routines are here as well.

|
|
* -------------------------------------------------------------------------
|
|
*
|
|
* The NuBus slot manager provides calls to manipulate slot parameter ram, the slot resource table,
|
|
* and fetching of information from a configuration ROM on an expansion card. It also scans slots
|
|
* at system initialization time, finding config ROMs and setting up the appropriate information.
