 Much of the functionality of this driver was determined from reading
 the source code for the Windows driver.
 
-The FPGA on the board requires initialization code, which can
-be loaded by comedi_config using the -i
-option.  The initialization code is available from http://www.comedi.org
-in the comedi_nonfree_firmware tarball.
-
-Configuration options:
-  [0] - PCI bus of device (optional)
-  [1] - PCI slot of device (optional)
-  If bus/slot is not specified, the first supported
-  PCI device found will be used.
+The FPGA on the board requires fimware, which is available from

+Configuration options: not applicable, uses PCI auto config
