PCIe - No parport registered at "0x " . This is not Always an error.Continuing.

Category: Advanced Configuration

sudo lspci -vnn
as said I before gives the name (generic) & PCI ID eg like
[4348:5053]
which is the important bit and what the kernel uses to load a driver.

correspondence of unused i/o pins to physical connector location?

Category: PnCConf Wizard

The .pin file in the firmware package has that info (if you know the firmware it was programmed with) or you can use mesaflash with the readhmid command (after adding the address & such)

example 7i96_5abob_d.pin file for 7i96 if programmed with 7i96_5abob_d.bit file
