Yes, I noticed that Linux Makefile interferes with the DDK build 
process, since both will try to use a file named 'Makefile', but I 
haven't figured a nice work-around, yet, to allow both build 
environments to use the same directory.

For some odd reason, I assumed you'd be building with MinGW under Linux. :)

It's nice to see someone else using those functions. :)  I already have 
another project that automatically installs and starts a driver up, as 
needed, so I was just going to copy it with minor changes.  It uses the 
functions you've mentioned, here.

That is the plan; yes.  It will automatically install and start the 
service, if needed, as mentioned...  Lots of simple copy'n'paste from 
other work.

Please note that physical memory holes will show up as "bad sectors" 
with the PMem driver.  You can skip past them or seek around them.
