you might want to extract your current rom using Universal BIOS Backup ToolKit 2.0 and opeining it with amibcp v 4.53

Find your unpacking folder: C:---> NVIDIA :---> DisplayDriver :----> 37X.xx ----> Win8_win7_64 :-----> International :-----> DisplayDriver

it was a trick question. usually you dont need any tools, you just get the flashed bios on a stick and use home+del while booting up or something to relash from the usb drive. Usually even if it's still bricked. But there is always de-soldering the chip and writing it way, of course. ebay can get you a chip writer for 5$ i think. I already have a modded bios, since i have replaced and upgraded my laptop's internal nvidia gpu + dyi'd the heatpipes for the new gpu. thank you and 'grats. i'll post your laptop model so people cand find it for quick reference: acer aspire v3-471g i7-3612QM 2.1 Ghz iGPU hd4000 / dGPU GT 640m / eGPU evga GTX 1050 ti sc exp gdc v.8 maybe people with your laptop model can find happiness as well with this dreaded 1050ti. the forum you were on is bios- mods dot co m , prolly. and those guys usually use amibcp to mod bioses, and use universal bios backup toolkit toolkit 2.0 to extract the original one.

Hotplugging isn't what you say it is. Start here: https://en.wikipedia.org/wiki/Hot_swapping Then read this: OUR problem here is USING it AFTER it gets detected.The problem is with the drivers themselves , not the MB not accepting/recognising the card. If the issue was with hotplugging, we'd use egpu 1.30 and just load a PCI dump that works, for example the wifi card. We would use it, in layman's terms, if the gpu would not be detected by windows, or it would have issues allocating. A few posts ago you asked for nv_dispi.....and i explained why it's useless above. Since you mention it works... i really gotta ask how were you able to mod your bios but you don't understand the nv-dispi ' s role. how did you mod your bios? what program did you use? did you use a chip reader? also, can you show us proof the gpu actually works? like a screenshot with dev manager, gpu-z with clock speeds and dxdiag ? or maybe ingame where you can select which gpu to use?

if. for example, on my asus, i dont have that option, not even hidden & locked . but that's not the issue. it gets allocated just fine.

NV_DISPI talk time Let's clear something out about this NV_DISPI.inf everyone is crazy about. It's not the holy grail and THE file that you need to worry about ! NV_dispi can be FINE and you're still screwed. Why? READ ON FOR ONCE: NV_DISPI.iNF is a instruction/ descriptor file that is used during install AND adds in your registry certain informations {HKLM } regarding copied files and their USE by Windows AND copy specific files from the display driver folder to the system folders (like system32 / syswow64 ) and activate specific services required by your GPU. Even if it's perfect , if a DLL is screwed or from another driver, you're screwed. And good luck finding out which of the TONS of dll's and registry keys is screwed. Thinking that just having the correct nv_dispi file will fix stuff, is ludicrous. It's like saying if you have instructions on how to build a rocket, you don't need the correct materials (dll's) Once again: nvdispi is a set of instructions to your pc as to -what deviceID that specific driver supports (THIS is what you can mod- desktop to mobile , otherwise 99% it wont work) -what files to copy for a specific deviceID from the mountain of dll's inside the driver folder -what registry keys system needs to ADDRESS the dll's and USE them for the display drivers -what services it will have/install/use for your display driver. -what other instructions it must follow if a specific dll / instruction table is copied (in my case, nvami- i have an ASUS) Why does modding nv_disp work from desktop to laptop? -if all these sound like mumbo-jumbo or you dont understand what they do/are , please stop right here. it's definitely out of your league. ( Acer & Gateway = nvaci.infAsus = nvami.infApple = nvaoi.infCompal = nvcti.infClevo (Sager & other re-brands) = nvcvi.infDell & Alienware = nvdmi.infFujitsu = nvfmi.infHP = nvbli.infHP = nvhmi.infLG = nvloi.infLenovo = nvlti.infMSI = nvmii.infNEC = nvqni.inf Siemens = nvfui.infSony = nvszci.infToshiba Qosmio = nvtdi.infToshiba = nvtsi.inf ....etc ) Why it works to mod the nv_dispi and nvami/etc to install desktop drivers on laptop edition gpu? -Because the gpu inside your laptop it's the same architecture as the desktop one, with (usually) same parameters , same processor, just "dumbed down" and underclocked like crazy so it can work with the power requirements your laptop has. -If the architecture is different, there is 99% chance it will never ever work, or just error out. Even if it's modded, if the dll you need (..GOD knows which ! ) , has a bad syntax somewhere....you're screwed. It's like forcing a square peg in a round hole and hoping the paint won't chip on either. Doesn't work like that. PS: An ENTIRE forum says it's not working ....and your "friend" says it is. I smell something fishy....as in i call bullsh*t. I think it's one of those troll posts like "i got it running! woot!...." and the guy disapears off the face of the planet after 2 posts. If it's NOT and it's legit, I want to see GPU-Z screenshot and dxdiag screenshot, display adapters screenshot of the integrated GPU, laptop model, setup , and windows version. And a benchmark, any benchmark, off the iGPU and Egpu.If not, it's bullcrap.. Why? It may look like it's working, but gpu-z wont give any readings off the Mhz of the gpu. 100%. It's an intermitent error I had sometimes when I installed 1050ti over the base drivers, and they somehow got mixed. The gpu doesnt work at all, and after you uninstall everything and DDU, you will get error 43, like normally. Even if it says it's working normally, gpu-z WILL NOT, i repeat...WILL NOT give correct Clock readings....aka: bogus installation. And I'm coming back to what the last 6 pages wrote,and NO ONE NEW TO THE FORUMS cares to READ: 1050 Ti DOES....NOT.... WORK ...OVER...mPCIE YET !!!! Stop littering the thread !

395 has more files than 372....so this is why you copy extra files from 395 over it.

mod nv_dispi AND nvdmi (or which it's yours) AND add whatever files miss from the 372.70 doesnt have (copy-paste it over,and say no to whatever's asking windows to override. It will install, but after a reboot the driver won't work. That's as far as i could go.

it is...unless you go ahead and buy gpu's that were not tested by the community. if you bought a 1050 ti like me...well...there's your problem. traded it for a 750ti and it ran instantly.

tried it with 372.70 ? or what version of drivers? the inf i see is win 10 64 bit 372.70

can you share the whole driver pack ? did you try a benchmark on them?

FOR THE LAST TIME! 1050/ti DOESNT WORK YET! ...not even with modded drivers. People that have working laptops with working egpu setups without blocks...cannot install it. You either see it as standard vga adapter, or with error 43, or, GPU-Z doesnt see it's real clock . speeds! Return it and get a 900 series, or wait a while.

nv_dispi.inf file? -tried that. didn't work. nvami?- tried that didn't work. (just to bust some myths....modded all the inf files in 372.70 with 1050ti info....and failed...the driver refused to work)

sold my 1050ti...bought a base msi 750ti....worked instantly with older drivers...50%+ firestrike score ( g75vw runs wifi mpcie at 2.0 x16 ....who knew?) . overwatch on ultra....@50 ish frames. I'm happy for now, a 980ti is in the works soon .it'll blow the roof , definetly.

it was the 1050ti. i plugged a 750ti, ddu-d all drivers, got 750's ancient drivers in,rebooted, installed the dgpu drivers, rebooted....EVERYTHING WORKS !! from 2660 score in firestrike, i jumped with 750ti to 3750. nvidia gave me the worst 3 nights I could ever have.....thought i had to mod my bios with 150ti's vbios or some sh*t.

last edit: the beast works fine, it was the new gtx 1050ti's drivers that are screwed. an older driver and a 750ti work flawlessly

I wonder why exactly doesn't the driver work.... ok, got the beast working....the 1000 series is doomed, esp 1050ti. installed a brand new 750ti and its 360.xx ...something drivers from long ago....dual monitors fired instantly .no problem. so it's the drivers fault. 100% I returned my 1050ti gpu back since it was an expensive paperweight, basically. laptop: g75vw - t1028D (for future reference if some1 is looking for info)

My recommendation is to hold your horses....cause it can work,and be cheap. I doubt thunderbolt would have any problem, since tbolt is better than mpcie in terms of issues. And since I've set it up in terms of issues, and FINALLY WORKS i recommend you guy a gtx 980 ti, with a PSU...and fire that baby up cause it will work! quick update: Got it working. https://gyazo.com/bc629d6d4597582938f75a7ca2dfb337 my setup: - asus g75vw with 670mx (from a g75vx- and I modded its bios) -beast exp gdc - <30$. beast mini PCIe version v8.4D -DELL DA-2 220W input for beast adapter. -gtx 750 ti from MSI (ANY card BELOW pascal 1050, 1060 and 1070-1080 series) that uses a driver BELOW 372.70) ORIGINAL firestrike: NEW firestrike: didnt need setup 1.30 Windows recognised it INSTANTLY plug and play LITERALLY. Steps to install it: -Plug it in on mpcie -turn windows on. -install DDU display driver uninstaller - uninstall ALL nvidia drivers. - reboot -install your new EGPU driver ( beware! install the older drivers BELOW 372.70) -reboot. -install your dedicated gpu drivers -reboot again -watch and be amazed on how your new egpu works: try gpu-z on both gpus, on egpu you should see core clocks...and then go in nvidia control panel in start menu (not gfe experience) and set up your gpu preferences.

Doubt you can make it work..it's the driver itself that's screwed..not the inf's...i modded the infs. didnt work. the 1060 driver wont work on 1050, even if forced. tried it.

Seems like the newer one dont fix the problem ,............ but error 43 is gone, tho. I tried fiddling with the 372.70 and making them compatible with 375.95 (taking a very long shot that 1060's drivers are 1050 compatible ) by manually inserting the devID and subsys manually into the nvami.inf (i have an asus). Acer & Gateway = nvaci.infAsus = nvami.infApple = nvaoi.infCompal = nvcti.infClevo (Sager & other re-brands) = nvcvi.infDell & Alienware = nvdmi.infFujitsu = nvfmi.infHP = nvbli.infHP = nvhmi.infLG = nvloi.infLenovo = nvlti.infMSI = nvmii.infNEC = nvqni.inf Siemens = nvfui.infSony = nvszci.infToshiba Qosmio = nvtdi.infToshiba = nvtsi.inf I was able to force an install...but to no avail. It said the driver is missing after a reboot. Soo....anyone kind enough or with the know-how to fix them?

Might wanna take a look at this: My eGPU recognises the external monitor but when I make it the primary it doesn't "turn on" and I'm simply reverted back to my internal LCDIf you see a brief flash on the external LCD then it could either be a faulty HDMI cable connected to the LCD or the PSU is insufficient to drive the eGPU to actually display something. I did encounter a intermittently faulty HDMI cause this problem.Also, Optimus drivers newer than 258.96 will cause this if using a DVI-to-VGA adapter I boot with the expresscard in my system. The internal LCD doesn't appear/work. Neither do I see x1.Opt performance (NVidia)These system's bios will use the eGPU as the primary video if it detects it on bios startup. That means the iGPU will be disengaged. Problem then is the internal LCD won't work and neither will x1.Opt since they are both reliant on a iGPU to be the primary video card.Solution is to boot past the bios with the eGPU switched off, then either: hotplug the EC2C by hitting F8 to stall the Windows boot proces power on eGPU, resume in Windows boot Setup 1.30 and hotplug if need PCI compaction I can't get internal LCD mode to work.This appears to be the case if you attach your eGPU after Win7 boots. So either hotplug your eGPU at the Win7 bootloader menu (hit F8 to pause bootup). Another option is to install and configure Setup 1.30 to detect your eGPU and configure your PCI configuration space prior to chainloading to Win7.AppInit_DLLs needs to be set for internal LCD mode to workFor games to launch on the internal LCD on systems with an intel iGPU, the AppInit_DLLs needs to route via a DLL. NVidia sets this to nvinit.dll. During my tinkerings I have seen this registry setting missing so internal LCD mode didn't work. [H] "AppInit_DLLs"="C:WindowsSysWOW64 vinit.dll"

join the club bro. g75vw with vx's bios & 670mx (instead of 670m) here , but over mPcie/beast. if you make it work...let me know please what you did. mine doesnt have issues over mpcie, it detects the card, but refuses to use it. sadly,i see the forum is kinda dead for now...prolly most ppl are thanksgivingin' for now. expect slow replys, from what I am seeing also. ps: this seems to be your problem: Upon powering my eGPU, the fan on the eGPU just spins faster and the card isn't detected. This indicates the eGPU is either not on the PCI bus or isn't getting 3.3V. Try unplugging, replugging the mini HDMI cable (expresscard solution) or hotplugging the PM3N (mPCIe solution). If the card is still not detected then connect the setup to another system's expresscard slot. It may be either a faulty expresscard slot or mini HDMI cable. Worth testing the eGPU in a desktop system as well. ^top I have problems running an Nvidia eGPU with an internal NVidia dGPU (supplied by nlooije/Khenglish) The trick is to get both an NVIDIA dGPU and eGPU working work under the same driver. This method assumes that the eGPU is detected in the device manager. If any errors such as code 12 or 43 are present check the corresponding items in the Troubleshooting section. If using the PM3N and it is not detected then maybe the mPCIe port is whitelisted, use the Setup 1.30 to unwhitelist. Download the latest drivers from the NVidia website or from this post by Tech Inferno Fan. Once the eGPU is detected, windows will automatically search for drivers through windows update. Cancel the search, and let windows install the standard vga drivers. In the device manager, right-click uninstall the dGPU and eGPU NVidia drivers. Use CCleaner to search for any residual Nvidia driversoftware and delete further. Install the latest Nvidia drivers. If everything went correctly then the installation software should ask permission to install the drivers twice, once for every card. Reboot and cross fingers. here's the troubleshoot thread:

I have a few questions regarding the 1.30...and ...I am a noob atit but I kindly ask someone to have a little patience with me. I have purchased a 1050ti, and device manager sees it, however....windows refuses to use it, and use its drivers. but displays the eGPU working properly. (more on my stupid predicament here): https://www.techinferno.com/index.php?/forums/topic/10516-error-43-with-nvidia-37290-and-newer-drivers-use-37270/&do=findComment&comment=152948 I have followed all steps to get 1.30 to boot before windows, step by step, like nando wrote in the htm file.So i get there,and it works. So at least that I did correctly. Trying to actually use my egpu: I am following this guy's step by step he used on a g74sx (i have g75vw....very similar) , and I am supposed to do this: And I get to letter E , this thread about DSDT override: I get to this: QUESTIONS I have: 1.How do I know if my port for egpu is g2? 2. even if i activate my eGPU, when i go to video cards list, it only shows my dGPU. 3. my dGPU when i try to disable it.....hangs. Or it doesn nothing. Should I get any confirmation it's off? It just says "disabling..." and...does nothing...minutes on end. 4.after all the operations in 1.30....how do I boot to windows with them active? (it's a really noob question, but it's the first time i hit myself with this problem.Sorry if I am a total n00b at it. 5.should there be a dsdt button in 1.30? it says dsdt=off in 1.30 Sorry to be annoying and/or boring with my questions but, I really could use someone in the know-how to give me a few minutes of his/hertime. I am clueless.

ok..narrowing it down...DDU'd all that i have in my pc, and installed my dGPU laptop driver.....dgpu works. installed eGPU desktop driver....error 43......BUT....gpu-z finally gets some (weird) readings off the 1050ti...it's not greyed out, but it shows bogus stuff like -1 mhz core clock. So the issue is, from what I see, that it just doesnt communicate with the egpu....or am I reading this wrong?

Odd thing...it says "device is working properly", and it shows the correct driver version...except gpu-z is 0 mhz and dxdiag says n/a. i read that thread and downloaded it but the 1050 1050ti wasnt out / supported in that version,i think. Should i mod that driver's inf files and manually try to add the devID and subsys?
