Instead of taking an unreadable photo of your monitor from the terminal window Edit > Select All then Edit > Copy then paste the result inside code tags.
Remove the spaces from inside the [] in the following example.
[ code ]
Lots of code
[ /code ]
Lots of code

Did you try "sudo cat /proc/ioports" ?

You said that this machine has an onboard parallel port?

Are you _sure_ it isn't disabled in the BIOS?

All that's in bios is one about serial port, nothing about a parport, .was going to take a good look at board and make sure there's not a required jumper maybe...

A picture of the backside of the PC?
Is it maybe a serial DB25 port?

I just checked, I have a duplicate computer running Windows and it doesn't see a paraport either, starting to think it's on board, but not active at all and will have to get para pci card. Nothing in bios, no obvious jumpers on board.

You could try 0x378 anyway, and ignore warnings. It might work.

LinuxCNC has its own driver that writes direct to the base address, so doesn't need any other drivers.

That said, if it doesn't show up at all I think you are probably out of luck.

I don't think that you have mentioned what the PC model is, but you could try a specific google search for that model and "how to enable parallel port" or similar.

Is it possible that the PCs have a custom BIOS due to being in a particular environment, and that a BIOS update to a generic one might help?
