-Driver: das16m1
-Description: CIO-DAS16/M1
-Author: Frank Mori Hess <fmhess@users.sourceforge.net>
-Devices: [Measurement Computing] CIO-DAS16/M1 (das16m1)
-Status: works
-
-This driver supports a single board - the CIO-DAS16/M1.
-As far as I know, there are no other boards that have
-the same register layout.  Even the CIO-DAS16/M1/16 is
-significantly different.
-
-I was _barely_ able to reach the full 1 MHz capability
-of this board, using a hard real-time interrupt
-(set the TRIG_RT flag in your struct comedi_cmd and use
-rtlinux or RTAI).  The board can't do dma, so the bottleneck is
-pulling the data across the ISA bus.  I timed the interrupt
-handler, and it took my computer ~470 microseconds to pull 512
-samples from the board.  So at 1 Mhz sampling rate,
-expect your CPU to be spending almost all of its
-time in the interrupt handler.
-
-This board has some unusual restrictions for its channel/gain list.  If the
-list has 2 or more channels in it, then two conditions must be satisfied:
-(1) - even/odd channels must appear at even/odd indices in the list
-(2) - the list must have an even number of entries.
-
-Options:
-	[0] - base io address
-	[1] - irq (optional, but you probably want it)
-
-irq can be omitted, although the cmd interface will not work without it.
