PCI and PCI-E add on cards with parallel port that work out of the box

I forgot to mention you also look in /dev to see how many nodes are made for the parallel port, and also look at what dmesg reports .

sudo cat /proc/ioports

Will return addresses

sudo cat /proc/ioports | grep parport returns only one set of addresses, (just to make sure)

So you have 2 parallel ports
A legacy on board port at 0x378 and your PCIe on at 0xccc8.

Nice to get responses and not have argue with a user. Thank you very much.

However this one here will probably work if I add the missing connector, capacitors and resistors.

PCI ID describes it as 1 parallel port + 2 serial ports (1P2S). 

It shows as a parallel port in dmesg and ioports and when I read the registers they are not empty (and numbers kind of make sense)

Sorry guys no pics but some info for 2 ,1 PCI & 1 PCIe (lscpi indentifies which is which) parallel from various resources on the machine. Will try later when got time to remove cards.
