If anyone has any insight on writing device driver (resource manager) in QNX
using National Instrument (NI) PCI-MIO-16E-1. I am trying to utilize the
DMA features on this PCI board. Thank you very much.

Go to ftp.qnx.com:/usr/free/qnx4/os/samples/misc, and retrieve
iomanager.tgz. This will get you a long way. As far as the rest goes,
the only QNX specific things you really need to know are the CA_PCI*
functions, how to mmap DMA safe memory, and the qnx_hint_attach function
(trivial), all of which are documented in the on-line docs.
