Parallel port controller issues, can not find address

I have setup a newer machine with LCNC to attempt to get past the locking up issue.  I am using my same Lava parallel port card in the newer machine.  Last install I used lspci -v to get the address of the parallel port card.  This time I get

03:02.0 parallel controller: Lava computer mfg inc lava parallel (prog-if 01 [BiDir])
Flags: slow devsel, IRQ 19
I/O ports at <unassigned>

I copied my setup from the old machine to this one   I was thinking somehow the 03:02.0 could translate to the address, I know I must have missed something in the setup of the PC.  Especially since all the I/O ports are unassigned.  I have not found anything useful in the searches so far that could lead to a solution.

Thanks!

sudo lspci -v
 
cat /proc/ioports | grep parport

Thanks Tommy,

I get the same output as above with

sudo lspci -v

What does the command below do? When I send that one, I just get a new line and nothing else. I'm in root@hurco:/home/hurco#


Thanks!

cat /proc/ioports | grep parport

Is there another free slot on the board? Try another slot.
I/O ports unassigned is strange, so is IRQ 19, i would expect IRQ 11 or lower.
Enter the BIOS and find anything related to parallel port, see if you can enable DMA.

Last night after a half day of not being able to make any progress on the network issue I dumped wheezy and installed buster. That fixed my network issue, that is the only PCIe slot I have. There is a PCI slot, I just need to get an adapter. I'll order one this morning. I'm going to head out to the shop in a bit and see what I can come up with now that Buster / 2.8 are installed

Here is what I am getting now with Buster and 2.8

03:02.0 Parallel controller: Lava Computer mfg Inc Lava Parallel (prog-if 01 [BiDir])
Flags: slow devsel, IRQ 19
I/O ports at 0000
Kernel modules: parport_pc


I have tried 0x378 and that does not get the job done. I am going to find the parallel port tester now that I have internet to the machine. See if I can run down the address that way

There is a PICe slot, which I ordered a card from the list on Pico's site.  Just when will it get here.....

The other two slots are different PCI slots, they have the rejection pin on the other side for internal cards like the video card ( which I am not using)

Try
0x0000

I tried that one with no luck.

I did find this, but it looks like it is specific to Redhat as one of the files it is talking about making the configuration changes in does not exist or I can not see it.

Linux holds the resource assignments of the parallel ports in the system. These resource assignments are in

‘/etc/conf.modules’file

as well as resource assignments of other cards such as network cards.The following is an example of the parallel port assignments in that file.alias parport_lowlevel parport_pcoptions parport_pc io=0x378 irq=7io=0x378 is the I/O assignment of the first (onboard) parallel port, and irq=7 is the IRQ assignments of the first parallel port. Initially, the Lava resource assignments will not be in this file. It is necessary to manually edit this file to add the resource assignments obtained from step (A) above.The following is an example the dual parallel PCI’s resource assignments added to this file. alias parport_lowlevel parport_pcoptions parport_pc io=0x378,0x6400,0x6500 irq=7,auto,auto


soooo I will keep hunting this evening.  It appears that it may be some setup conflict.  This Lava single parallel port card has been functioning for 6-7 years now with this machine.  It was also working with LCNC 2.7x I just never made it to 2.8x with the old PC in there. 

Thanks again for the help!!!

New parallel port card is in. Just have not figured out what the address is

lspci -v

Region 5: Memory at f7c00000 (32-bit, non-prefetchable) [size=4K]

Still digging to figure out what it can be. Also the capabilities is kinda odd.

Region 0: I/O ports at e010
Region 1: I/O ports at e000

Those are the port addresses, start with the first one
0xe010
