I am using "EXP GDC Beast",
The limitation is on PCIe lanes - only 1x or 2x. The pcie version is probably
v2 because of laptop age.
The EXP GDC hase some CTD and PTD settings as seen in link, but I am not sure
what it does. (nvidia works in current settings)

The laptop can boot via BIOS and via EFI. I did EFI installation, since I read
it was better for such setups.

I am using kernel parameters pci=norcs and pci=realloc - I don't know why, but
nvidia does not work without those parameters.
I think "pci=realloc" is for kernel memory allocation, but this is different
than "PCI BAR" right?

Where can I ask about PCI BAR issue?
