The driver supports DaqBoard/2000 and DaqBoard/2001. DaqBoard/2000 has 2 AO channels, but DaqBoard/2001 has 4 AO channels. The driver currently only supports 2 AO channels, but supporting 4 channels is just a case of setting the `n_chan` member of the COMEDI subdevice to 4 instead of 2. Add a new boolean flag member `has_2_ao` to `struct db2k_boardtype` to be set to `true` if the board only has 2 AO channels. Set this to `true` in the element of `db2k_boardtypes[]` that corresponds to the DaqBoard/2000. Use it in `db2k_auto_attach()` to initialize the number of AO channels to 2 or 4, as appropriate.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
