Hi,

You need (or what i used):

- PE4L 2.1b (SW1 = 1, SW2 = 2-3)

- DIY eGPU Setup 1.2 (PM Tech Inferno Fan for pruchase)

- NVidia GPU (Asus GTX 780 (no OC) in my case)

- PSU with enough power

- ThinkPad W530 (see sig.)

1. Connect your PE4L with the GPU and the PSU etc. (dont plug in the Expresscard)

2. Download the latest NVidia Desktop drivers (320.18 for me), but dont install yet

3. Install the DIY eGPU Setup 1.1b5 + update

(i had to manually copy the files from V:\V_ to the destination folders)

4. Shutdown your Notebook

5. Power on and hit Enter + F1 to get into BIOS

6. Display settings -> change (if not already) it to "NVidia Optimus" + OS detection "enabled"

7. Save and reboot + power on your eGPU but dont plug in the Expresscard

8. Wait until you see the bootmenu with "Windows 7" and "DIY eGPU setup 1.1b5"

9. Plug in the PE4L in your Expresscard 34-Slot

10. Enter the eGPU setup and go to menu-based-setup

11. Change the following settings:

- dGPU off

- compaction 32-bitA on eGPU and iGPU

12. Hit Chainload mbr -> Windows 7

13. In Windows Install the NVidia driver you downloaded

14. In V:\config\startup.bat change the last lines to:

call speedup lbcache

call iport dGPU off

call vidwait 60 10de:1004 (your Hardware IDs may differ)

call vidinit -d 10de:1004 (your Hardware IDs may differ)

call

call pci

call grub4dos mbr

and save it.

15. Shutdown and detach the PE4L from the Expresscard-Slot

16. Start the Notebook and wait until you see the bootmenu -> plugin the PE4L and start eGPU Setup + startup.bat (hit 1) -> Windows 7

17. Now it should working. Check it in devicemanager (disable NVidia HD audio) + check Optimus in NVidia control panel (PhysX to CPU):

18. If you want, you can change the bootmenu time, order etc. with something like EasyBCD.
