+Driver: ni_atmio
+Description: National Instruments AT-MIO-E series
+Author: ds
+Devices: [National Instruments] AT-MIO-16E-1 (ni_atmio),
+ AT-MIO-16E-2, AT-MIO-16E-10, AT-MIO-16DE-10, AT-MIO-64E-3,
+ AT-MIO-16XE-50, AT-MIO-16XE-10, AT-AI-16XE-10
+Status: works
+Updated: Thu May 1 20:03:02 CDT 2003
+
+The driver has 2.6 kernel isapnp support, and
+will automatically probe for a supported board if the
+I/O base is left unspecified with comedi_config.
+However, many of
+the isapnp id numbers are unknown. If your board is not
+recognized, please send the output of 'cat /proc/isapnp'
+(you may need to modprobe the isa-pnp module for
+/proc/isapnp to exist) so the
+id numbers for your board can be added to the driver.
+
+Otherwise, you can use the isapnptools package to configure
+your board. Use isapnp to
+configure the I/O base and IRQ for the board, and then pass
+the same values as
+parameters in comedi_config. A sample isapnp.conf file is included
+in the etc/ directory of Comedilib.
+
+Comedilib includes a utility to autocalibrate these boards. The
+boards seem to boot into a state where the all calibration DACs
+are at one extreme of their range, thus the default calibration
+is terrible. Calibration at boot is strongly encouraged.
+
+To use the extended digital I/O on some of the boards, enable the
+8255 driver when configuring the Comedi source tree.
+
+External triggering is supported for some events. The channel index
+(scan_begin_arg, etc.) maps to PFI0 - PFI9.
+
+Some of the more esoteric triggering possibilities of these boards
+are not supported.
+*/
+/*
+ The real guts of the driver is in ni_mio_common.c, which is included
+ both here and in ni_pcimio.c
+
+ Interrupt support added by Truxton Fulton <trux@truxton.com>
