Hello folks -
I have struggled for days figuring out how to install my Lenovo Y450 with eGPU GTX 560TI. Thanks to Nando for all the help. He's been patient with all of my stupid questions. Also, you need to have a lot of PATIENCE and LUCK (for the driver)!
NOTE: THE LAPTOP MONITOR CANNOT BE USED AS YOUR MAIN MONITOR FOR THE GTX560Ti. That is unless you apply the Chung Gun/Ultramon method that drags a *windowed app* from the eGPU LCD (virtual) to the internal LCD.

Hardware configuration
Lenovo Y450 T6600 2.2Ghz CPU
8GB RAM
NVidia G110M dGPU, no iGPU
Windows 8.1 Preview 64bit
eGPU:
PE4H v3.2 EC2C (express card)
Thermaltake ATX 430 Watts
NVidia GTX 560Ti
Installation steps
1. Install DIY Setup 1.20 or newer.
2. Run windows and disable driver signing and enable testing. Download unified 320.20 driver containing both the G110M and GTX560TI PCIIDS: LaptopVideo2Go: Drivers
3. Clear all the nvidia drivers using Guru3D video sweeper.
4. Reboot.
5. Select Setup 1.x from the Windows boot menu
- PCI Compaction->Run (I got 256MB free)
- PCI Ports->Hot Reset Port (select the eGPU)
- Video cards->Initialize the eGPU
- Chainload->Test Run (MBR)
I hit F3 after each one so it was automatically added to my startup.bat, though vidinit needed to be manually moved to be after 'call pci' else it BSODs. Means on subsequent runs I only need to select the "automated startup via startup.bat" boot option and not navigate the menus:
call speedup lbacache call vidwait 300 call iport reset 2 call pci call vidinit -d %eGPU% call chainload mbr
6. Boot Windows 8.1 Preview in safe mode
7 . Install the unified 320.20 driver. Install from untrusted driver - click it when prompted.
8. Reboot
9. Do step 5 but when chainload to Windows bootloader in (6) run it in normal mode
