CBPRES: DMA Engine Present Control Register
This register provides control for suppressing access to the configuration space of
selected devices within the Intel
disable DMA Engine configuration and memory mapped operations to device 8, function
0 and device 8, function 1 respectively. This is a special register intended to suppress
the “yellow-bang” warning for the DMA Engine device for Intel
customers who install non-standard operating systems without associated drivers. It
can also be used as a defeature mode to block DMA Engine technology from being
used.
