No parport registered

Hello friends!
I had a machine running linuxcnc normally.
I use the version LinuxCNC 2.8.2 Debian 10 Buster PREEMPT-RT ISO
I went to change the motherboard and parallel port and now it prints the following message


no parport registered at 0xe000


lspci shows the following parallel port:

tried as two separate ports to no avail:

loadrt hal_parport cfg="0xe010 out"

proc command returns nothing
cat /proc/ioports|grep parport*


need help.
thanks

 

I saw this problem, a week or two ago on IRC.

Which make and model card is this?

forum.linuxcnc.org/27-driver-boards/3439...l-cards-what-chipset

@marceloBrazil Can you try lspci -vv as root or sudo and post the relevant output?

I think it's some  newer non-standard chip used or clone device.

PCIe MCS9900 strangeness: Capabilities: <access denied> Saw this helping someone with the same card a few months ago on IRC.

LCNC 2.9 Stepconf does not recognize the card either.

The better fix will be adding these PCI addresses to the kernel.

I'm sorry but when you dumb down the LPT ports to 0 and 1 how do you know which one is which when you have 2 LPT ports without trial and error?

StepConf did not let me edit the LPT port when it could not find a LPT port.

revert: Removed the option of manually inserting the parallel port

Is fixed now! \0/
