	  This is support for Future Domain's PCI SCSI host adapters (TMC-3260)

	  and other adapters with PCI bus based on the Future Domain chipsets

	  (Adaptec AHA-2920A).



	  NOTE: Newer Adaptec AHA-2920C boards use the Adaptec AIC-7850 chip

	  and should use the aic7xxx driver ("Adaptec AIC7xxx chipset SCSI

	  controller support"). This Future Domain driver works with the older

	  Adaptec AHA-2920A boards with a Future Domain chip on them.



	  To compile this driver as a module, choose M here: the

	  module will be called fdomain_pci.
