In case you own a Lenovo Y410p or Y510p laptop, you might be interested in upgrading its performance by installing an external graphics card. Ultrabay eGPU adapter designed by @gerald was proven to be a convenient plug-and-play option to do exactly that. However, for a long time only an AMD-branded GPUs could be used due to limitations in the Lenovo's stock BIOS. The purpose of the modified firmware presented here is to expand the range of available GPUs by enabling Nvidia support on Gerald's Ultrabay eGPU adapter.
Huge thanks to:
@MWichni - For efficiently assisting me during the development of this mod. By flashing dozens of BIOS builds over the course of several weeks and thoroughly describing the effects observed (or the lack thereof), he enabled me to fully understand necessary parts in BIOS structure and come up with a final solution. @svl7 - Whose unlocked BIOS / Whitelist mod has served as a basis for this modification. His discovery of a security hole in V2.07 BIOS has provided us with a convenient BIOS flashing method that does not require a physical programmer. The Unlocked BIOS and WLAN whitelist mods originally designed by him are also implemented in this BIOS mod. @gerald - For designing the aforementioned adapter. Without it, all this work would make very little sense.
Resolves the "40-second reboot" issue normally encountered while using Nvidia graphics cards with Ultrabay eGPU adapter, thus allowing all Nvidia cards to be used. Based on the latest V3.08 BIOS. Includes Svl7's WLAN whitelist removal mod - for the convenience of aftermarket WLAN card users. Includes Svl7's BIOS debug menu mod - for the ease of experimentation with newly available features, e.g. attempting to use Nvidia Optimus to pass eGPU video back to laptop's display.
NB! Svl7's Debug Menu is not a toy! It contains a lot of options that are either not supported or partially supported by the hardware platform and/or can disturb its normal operation or prevent the PC from booting up at all. Any of the entries not originally present in the stock BIOS should be modified at your own risk!

If things don't go right:
If you intend using the GTX10XX-series Nvidia card as the eGPU (which you probably do), you are very likely to encounter the infamous Error 43 in Windows Device Manager. This is a widely known issue in the eGPU community and is not related to this particular mod in any way. Following this guide thoroughly will in most cases resolve the Error 43 issue.

Version of this mod for Lenovo Y400/Y500 models is coming soon!
Hi to everyone , I have troubles to eliminate the error 43.
I have beast 8.0
EXpress card cable
cx650M Source power
I have tried to install different versions of driver nvidia but the error persists.
When I start the laptop and the power supply at the same time I have a black screen. but if I wait about 10 minutes and then I turn OFF the laptop the restore computer appears , seems like the laptop worked normally (but I have no video signal).
Sorry for my poor english.

Ich habe mir zu Weinachten eine Akitio Thunder 2 mit einer EVGA GTX 1060 6gb für meinen late 2013 IMac mit einem 120W AC Adapter von Leicke geholt.
Zu meinem Problem, Ich habe alle mögliche Treiber probiert ich habe mein Windows zweimal neu aufgesetzt und
habe verschiedene Sachen im Geräte Manager deaktiviert. Was kann ich da jetzt noch machen das die evt. doch geht?
Danke schon mal im voraus

So my laptop (latitude e6430) has an expresscard, so I wanted to get a eGPU for it. I did some research, and already got the adapter, but theres one thing I need. I need to know what is my TOLUD and what GPU should I buy for it, respectively. Here I attach a screenshot of my device manager and my laptop's specs so that someone may help me. If I got this right, my tolud should be 3.5Gb. Is this true, and if so, what GPU should I buy?
note: sorry that the screenshot is in spanish, but I dont think that should matter
Hi guys, I need some help from you guys if you wouldn't mind. I'm useless
I7 2720qm @2.2ghz
1x HDD 500gb
1x HDD 300gb
Nvidia GTX 650 Ti BOOST
EXP GDC BEAST 8.5c
DIY Setup 1.3
DELL 220w PSU
After a lot of messing around I have managed to get this egpu to work when downgrading to 2gb, Which makes me think I just need to change my TOLUD to get it to work. I have read and tried to make a successful DSDT file however I don't really know what I'm doing with these driver edits and haven't been able to get it to work particularly the error fixing on compiling the dsdt.
However When I did have it working on 2gb ram. I ran heaven Bench, The GTX 650 under load makes strange noises and crashes the display driver multiple times. Could any of you more knowledgeable individuals give me a hand please Thanks
