The picture shows a purple port, but in fact my one is blue. I think that I have a serial port not a parallel one. I will buy a parallel board, is a cheap board....

An expensive ($80) alternative to a PCI parallel port is the Mesa 5i25. That can have exactly the same pinout as a Parport, but generates steps and PWM in the card hardware,

Well...

I consulted the Bios and the PARALLEL PORT is there, like this:

Parallel Port Address: 378
Parallel Port Mode: Normal
Parallel Port IRQ: IRQ7

Any ideas?

I got some additional information from system information, see png attached

I think all that shows us is that the parport module is loaded.

I don't actually think it should be, but I could be wrong. It may be that that module is fighting with HAL for control of the port.

What's your suggestion Andy?
Sorry about that but I cant understand Linux yet... and thanks the patience of the group with me
This System Monitor I just downloaded to see the hardware functioning in a way more friendly for me, yet I did not understand where is the problem, is a matter of configuration or is the hardware...
I checked every file (as chapter 9 of integration manual, and troubleshooting 10 and 11) and all suggestions made by the group, yet no results. I think that there is another command overriding my parport. like printer or some INI files (I hate not understand Linux yet)

Other modules can take over the parport so that LinuxCNC can't find it, but it still should show up in /proc/ioports (and generally in lspci too, but not if it isn't a PCI device).
There might be a BIOS option to "enable legacy ports" or something?
The fact that the BIOS mentions a parallel port seems hopeful. If you have a 25-way D-sub on the back of the board then it is extremely unlikely to be anything but a parallel port.

Can you change the Mode of the parallel port in the bios?
Is it possible that there is an enable /disable setting hidden in the bios somewhere?

This is really a long shot.
Perhaps try booting from the live CD from both 8.04 and then 10.04 and looking for the parallel port from there.
See if it shows up using the same methods outlined before.

I ran thru Bios again.

Just before Parallel Port it has an option "Serial Port1 Address [3F8/IRQ4]", I can choose [Disable] for that - Do you think that this can be the problem? (I didn't change that once I don't know if it will impact my monitor (video) - I suck regarding hardware definitions, my bad)

On the Parallel Port mode, that is [normal] I have the options [EPP] [ECP] and [EPP+ECP] but I don't know what does it mean.

And than, on PCI/PnP Settings, it has one option sayin "Plug an Play O/S - [No]" and I can change for [Yes]

Can't find "enable legacy ports" in Bios.

Any thoughts?
