I'm a little puzzled by the parallel port allocation.

http://linuxcnc.org/docs/2.4/html/examples_pci_parallel_port.html

When I do the lspci -v I'm not told where the motherboard parallel port is but 
the one plugged into the bus comes up at 

I/O ports at 3008 
I/O ports at 3000


If I connect my parallel port cable to the board I just plugged in and modify 
the hal file 
loadrt hal_parport "cfg=3000"

I get an error when Linux CNC starts up 
Linux parallel port not found @12288
Which is the decimal version of 0x3000

Yet, since I'm plugged into it, the system does work.  Step/dir limits etc.
If I try 3008 which is the other address reported by lspci it reports it can't 
find that one @12296 but now the hardware doesn’t function.

So when I use 3000, which does work, why the bogus error message?

And in case someone is thinking, why even bother, the answer is that I'd like 
the one at 3000 to be the second parallel port but when I have both set up with 
loadrt I still get that not found message.

Very confusing
