The Daqboard/2000 uses a PLX PCI-9080 chip to interface with the PCI bus. The "daqboard2000" driver uses the PCI-9080 "CNTRL" register to perform various tasks, but defines its own macros for the register values. Use the macros from "plx9080.h" instead. The various functions that change the CNTRL register just wiggle individual bits up and down, but they ignore the current register value - the old macros defined the full value to be written to the register. Change them to read and modify the register value. Also remove a read of the CNTRL register in `daqboard2000_auto_attach()` where the value is just thrown away, as it seems to serve no purpose there (such as flushing PCI writes).

README
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.
