NAME    [Toc]    [Back]

       do_config  -  EISA/ISA:  Initializes  the  device  to  its
       assigned configuration

SYNOPSIS    [Toc]    [Back]

       void do_config(
               struct controller *ctlr_p );

ARGUMENTS    [Toc]    [Back]

       Specifies a pointer to the controller structure associated
       with  the  controller to be configured. The do_config routine
 obtains the device to  initialize  through  its  controller's
 associated controller structure pointer.

DESCRIPTION    [Toc]    [Back]

       The do_config routine initializes the specified controller
       based on its power-up resource assignments. If the  device
       uses  either an interrupt or a DMA channel, then do_config
       also performs any setup  requirements.  For  example,  for
       controllers  that  connect to the EISA bus, do_config initializes
 the controller according to the parameters specified
 in the EISA configuration file.

NOTES    [Toc]    [Back]

       The  do_config routine is a generic interface that maps to
       a bus-specific interface  that  actually  initializes  the
       specified  device.   Using  this  routine  to initialize a
       device makes the driver more portable across different bus
       architectures.  Not  all  buses support the do_config routine.
