Basic IO Test with Parallel port

Thank you for your patience.
Yes, there is a tool included with LinuxCNC for exactly that, from the menu start LinuxCNC and on the config picker choose "sample configurations" then "apps" then "parport" and one of the two choices, it will ask to copy so OK but it will not work for you now, you have to close it, navigate to the configs folder and edit the hal file by adding the address of your parallel port, save, and start by right clicking on the .ini file and choosing to run it with LinuxCNC.
To test, attach the BOB and check the BOB manual on how to trigger the inputs while checking the LED's on screen.

No, not LinuxCNC, that should be set in BIOS, something like resource assignment should be set from auto to manual, meaning the PC at boot time assigns addresses and IRQ's for PCI cards and everything in it.
