I'm looking for a debug card with pcie connection, before I order and make a mistake, do you have any suggestion?
The one I think is right cost in the tens of €, or it's a laptop card costing nothing.
I now have some motherboards without a PCI slot so I have to buy a new card to try to understand what is going on.
Thanks!

Good question ! I do not know but would like some good info on any that members have bought and used.
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
Im not sure PCIE even transmits IO port writes
laptop mpcie cards are special - they dont connect to PCIE switch but instead to LPC pins in some notebooks Mini-PCIE slot:

"3. The Mini-PCIE interface in the Combo-POST CODE-Card
Mini-PCIE is used as a trend in the new notebooks. Compared with
Mini-PCI, Mini-PCIE occupies less space. This Combo-POST
CODE-Card doesn’t use all of the Mini-PCIE bus pins. And only the
below pins are used: PIN-8, PIN-10, PIN-12, PIN-14, PIN-16, PIN-17,
and
PIN-19. In the Mini-PCIE spec, those pins are reserved, and it is not
standard, so some of Notebook manufacturers define it as a LPC
POST CODE-port."

Your best bet is a debug card with LPC support, such as:

unfortunately these aren't cheap, you'll need to figure out how to wire it up for each individual motherboard, and there's no guarantee it'll work with any given motherboard.
That's what I thought, it's the costly one and it's not as straight forward as the old PCI/ISA ones.
The price is high enough to make me ponder.
Thanks for all the input.

.. as I said ANY mpcie card is actually LPC, like $12.99 "3in1 PC Laptop Analyzer Mini PCI Mini PCI-E LPC Tester Diagnostic Post Test Card" or $12.00 "Post Card Diagnostic 3 in 1 miniPCI/PCI-E/LPC motherboard Analyzer Tester 6digit" or $3.98 "Mini 3 in1 PCI PCI-E LPC PC Laptop Analyzer Tester Diagnostic Post Test Card"
the $60 fancy one is typical scam by omission. PCIE port is non standard, its a proprietary Gigabyte solution and works only on select Gigabyte boards.
