  Modified:    sys/dev/aic7xxx  aic7xxx.seq aic7xxx_reg.h
  Log:
  Fix problems dealing with non-tagged devices when SCB paging is enabled.
  Mostly this involved changing the semantics of the findSCB routine so that
  it could be used at times other than handling a reconnection.

  Modified:    sys/i386/conf  GENERIC options.i386
  Log:
  Add two new aic7xxx driver options:
  
  AHC_FORCE_PIO - This forces the driver to use PIO even on systems that
  	say they have memory mapped the controller's registers.  This
  	seems to fix Ken Lam's problems.  I've also placed this option
  	in the GENERIC kernel file so that we are guaranteed to install
  	even on these flakey machines.
  
  AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
  	the 398X controllers allowing a totoll of 255 non-paged SCBs.
  	This doesn't work quite yet, so this option is mostly here to
  	help 398X owners to experiment and give me feedback until this
  	works properly.

  Modified:    sys/i386/eisa  aic7770.c
  Log:
  Add some code to allow SCB sharing for the 398X cards.  This involves passing
  an extra parameter to ahc_alloc.

  Modified:    sys/i386/scsi  93cx6.c 93cx6.h aic7xxx.c aic7xxx.h
  Log:
  Add basic support for the 398X cards as multi-channel SCSI host adapters.
  This involves expanding the support of the SEEPROM routines to deal with
  the larger SEEPROMs on these cards and providing a mechanism to share
  SCB arrays between multiple controllers.
  
  Most of the 398X support came from Dan Eischer.
  
  ahc_data -> ahc_softc
  
  Clean up some more type bogons I missed from the last pass.
  
  Be more clear when handing the NO_MATCH condition.  NO_MATCH can also
  happen when the sequencer encounters an SCB we've asked to be aborted.
