-These boards are almost identical to the AT-MIO E series, except that
-they use the PCI bus instead of ISA (i.e., AT).  See the notes for
-the ni_atmio.o driver for additional information about these boards.
-
-Autocalibration is supported on many of the devices, using the
-comedi_calibrate (or comedi_soft_calibrate for m-series) utility.
-M-Series boards do analog input and analog output calibration entirely
-in software. The software calibration corrects
-the analog input for offset, gain and
-nonlinearity.  The analog outputs are corrected for offset and gain.
-See the comedilib documentation on comedi_get_softcal_converter() for
-more information.
-
-By default, the driver uses DMA to transfer analog input data to
-memory.  When DMA is enabled, not all triggering features are
-supported.
-
-Digital I/O may not work on 673x.
-
-Note that the PCI-6143 is a simultaineous sampling device with 8 convertors.
-With this board all of the convertors perform one simultaineous sample during
-a scan interval. The period for a scan is used for the convert time in a
-Comedi cmd. The convert trigger source is normally set to TRIG_NOW by default.
-
-The RTSI trigger bus is supported on these cards on
-subdevice 10. See the comedilib documentation for details.
-
-Information (number of channels, bits, etc.) for some devices may be
-incorrect.  Please check this and submit a bug if there are problems
-for your device.
-
-SCXI is probably broken for m-series boards.
-
-Bugs:
- - When DMA is enabled, COMEDI_EV_CONVERT does
-   not work correctly.
