Intel DG41MJ Not finding Parallel Port

Well, I did get a clean install. Now I'm getting an error I've never seen before.

I get the debug screen when I tru to run LinuxCNC

DEBUG FILE INFORMATION

insmod: error inserting '/usr/realtime-3.4-9-rtai-686-pae/modules/linuxcnc/hal_parport.ko': -1 Resource temporarily unavailable
./3020T_CNC.hal:6: exit value: 1
./3020T_CNC.hal:6: insmod for hal_parport failed, returned -1

I'm looking through the forum to see if this is covered.

Clean install. Had a few startup errors running LinuxCNC.

Getting closer. LinuxCNC now runs, but still does not give the power clicker or able to run tests in stepconf.

As far as i remember, that happens when setting the wrong address and it will not work without rebooting the PC and fixing the address.

I did get past that. Getting closer.

I blacklisted lp

cat /proc/ioports
0378-037a : parport0

CNC.hal
loadrt hal_parport cfg="0x0378 out"
setp parport.0.reset-time 3000

I tried both ways
loadrt hal_parport cfg="0x378 out"

I'm at a loss.

Does that mainboard have a BIOS at all ?
There must be settings for parallel port, you need to set it to EPP or ECP mode in bios, set it to use DMA and IRQ, otherwise it will not work.
You have it set as Tristate and not using IRQ ( IRQ 0 is reserved, can not be used by parallel port).

I did mention I had it set for bi-directional. I reset it for EPP, It doesn't give the option for Tristate. Just asks enable or disable and mode EPP, ECP, or bi-directional is all it gives.

It doesn't give a choice for DMA or IRQ.

I'm re-installing. I've made so many changes I now have two parports and even deleting all conf & modules entries they don't go away on reboot.

After a full clean install before installing the RTAI kernel

cat /proc/ioports now shows two parports. Is the EPP setting causing this?

0378-037a : parport0
037b-037f : parport0

dmesg now shows the Tristate & EPP & IRQ 5 you talked about.
I'll now install the kernel and see if it keeps this all.

So far might be doing good. The only thing different from this install and the previous one is I didn't remove a lot of bloatware.

Now to install LinuxCNC and see what happens.

dmesg | grep par

Still not getting the power clicker when I run the program, and did not work when trying to test during stepconf.

I think I need to give up on this. Nothing seems to be working at all.

The only other thing different is the Hard drive is a 1T. The old IDE drive in the older board is 80-gig.

I guess I could try a 160-gig drive. But don't really think that would be a problem.
