2 Parallel Ports - 1 Intenal, 1 PCI Parallel Port Card not configuring

Hi!I am an old timer from DOS age. I do know Windows but TOTALLY new to Linux or LinuxCNC. I am using an old HP Z210 with 1 integrated Parallel Port (Set to Bi-Directional or EPP/ECP).
I have successfully installed LinuxCNC_2.9.2-amd64.hybrid on the computer. The problem is the integrated parallel port does not register in LinuxCNC. I have checked the net and used some of the suggested commands to find the port. It seems the problem is allocation of parallel port somewhere else. I am attaching the command results. I would appreciate any help.
Regards

It is finding it on some of the results but not on lspci?
First check if it is enabled in BIOS

When you mean "not register in linuxcnc" what do you exactly mean ? What errors are you getting ?
As far as the OS in concerned the onboard Parallel Port is being detect.

sudo dmesg | grep parport


The issue would appear to be with the plug in card, no driver seems to be loaded.

I would conclude the on board PP is fine, the Plugin Card is the issue. Remove the Plug in card and try a simple config with just the on board parallel port

Try, this will let us see the PCI id of the plug in card and determine what driver, if supported, should be load.
lspci -nv

sudo lspci -v

OP has already run lscpi -vv

lspci -nv will bring up the PCI id as well. From there we can work out driver support. Not that it matter than much, unless the driver sets up any on chip registers.

But I've never had much luck xeon processors, one was with a single cpu workstation class machine and another was with a dual cpu server class with realtime.

For me it is the opposite, every Xeon i had was good latency vise!
A bit fuzzy from lack of sleep, but using sudo for lspci shows also the stuff that normally says "access denied", although for parallel port that does not list it changes nothing.
