+ 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.
