Hello everyone!
I'm trying to make my first eGPU setup as an inexpensive performance boost for an old laptop:

Laptop: Dell Studio 1555, BIOS A06
OS: Linux Mint 64-bit (Windows dual-boot)
GPU: GeForce GTX 560
Dock: EXP GDC Beast (Expresscard)
Power: 8-pin Dell DA-2

Sadly, I'm stuck. I assembled everything and rebooted the laptop, which got the fan to spin on the card, but beyond that when I run

lspci | egrep 'VGA|3D|NVIDIA'

my output shows that only the laptop's integrated Intel GPU is detected:

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

So like I said, I'm befuddled. There are no options in BIOS to change any graphics selections. I tried with the ATX PW switch both ON and OFF and kept PTD at OFF. I also waited until after boot to plug in the Expresscard, with no change. There are two 6-pin connectors on the card; do I need to power one or both of those for the card to work at all? I would think if the fan is spinning that there is power and therefore it would be detected, but that's clearly not the case.

Thanks in advance for any suggestions; if there's no solution maybe it might be a sign to let this old laptop die and find something more capable, but I figured I'd give it a shot anyway.

hey~
I succeeded in installing on the same system.
The graphics card could not be seen in Device Manager and I had to patch the DSDT.
i had setup problem, but it works perfectly now.
check the link below. good luck~

That's good for windows, but DSDT isn't applicable to Linux. I think the boot parameters 'pci=noCRS' or 'pci=noacpi' or 'acpi=off' would be things to try.
