+## Agilent Interferometer PCI cards
+
+The Agilent PCI cards don't have a proper kernel driver any more and are now accessed by Orocos directly via the PCI slot. To configure access, use `lspci` to see which PCI address (number on the left) corresponds to your Agilent card and make sure that your `start.ops` includes lines similar to:

+```
+import("SensorAgilentPCI")
+loadComponent("Sensor1","SensorAgilentPCI")
+Sensor1.deviceName = "/sys/bus/pci/devices/0000:07:00.0/"
+```
+
+You should be able to see a directory in your file system that matches the `deviceName` string.

 ## Identify Device Numbers
 
 The device numbers assigned to each card can be found in the kernel message log, which is printed with `dmesg` (might need `sudo dmesg`). There can be a lot of messages to sort through, so you can narrow it down with `dmesg | grep comedi`. This should produce output that includes lines like (example from PolLux):

 We are looking for messages in the format of `comedi4: ni_660x:`, which tells us that an NI6602 card (with `ni_660x` kernel module) has been assigned the device number `4` by Comedi. Further information can often be found in the lines in between those containing "comedi" and you can use the timestamp on the left to quickly find the appropriate section of the message log. Some other useful commands for identifying hardware include:

 If you have multiple cards using the same driver, then it can be a bit complicated to figure out which is which. As a rule, Comedi will tend to assign a smaller device number to the card with the higher PCI address.
