I need to remove UEFI GOP from vBIOS not update it similar to here: [Guide] Remove UEFI Image from NVIDIA vBIOS - #18 by brothertax
Laptop has no uefi and any gpu with uefi gop in vBIOS causes no boot. Not sure if removing uefi gop using that method and flashing with my ch341a programmer will brick card. MXM Quadro have signature requirement in vBIOS. Idk if that mod alone will break any signature.
and did you read the topic?
if you not have hybrid or legacy vbios ,.,.is impossible use this card on LEGACY
or in bios CSM BOOT - VGA MODE - LEGACY āthis disables GOPā
send your notebook name and gpu ID / SUB-ID
i will try find compatible vbios or setup
Alienware M17xR3
You will not find anything that will make it work online.
Only option is bios mod to fix UEFI incompatibility or vBIOS mod removing UEFI GOP portion of vBIOS on the RTX 3000 MXM card.
but when have full uefi card ,.,.not works without GOP ā¦this is problem 
send vbios or ID + subID ??
and bios is INSYDE ? .,.,.,try find on TECHPOWERUP - vbios in HYBRID structure / or must contact gpu manufacture for LEGACY vbios āif is this possible for new cardsā
AFAIK no modern GPU has a ālegacy onlyā vBIOS, they are all hybrid/UEFI now and have been for some years. The last GPU you could really dive in and mess with was the Polaris cards for AMD or the Maxwell II cards for nvidia. GPUs are boring as shit now.
but hybrid must works also on legacy mode ?
,ā¦,my hybrid/UEFI vbios works fine under LEGACY and UEFI mode āpascal MXMā 
edit
also legacy vbios probably exist āor any corruptā i saw some MSI notebooks and they didnāt have UEFI signature āPASCAL / RTXā
Yeahā¦but is putting modern RTX3xxx MXM on an hybrid UEFI 2011 system.
Bios cant load/deal with the NVdia hybrid vbios legacy part or own GOP
or
the RTX3xxx requires a modern CSM module on bios itself.
i agree
or like another notebooks - EC fw /PEG setup / SA setup / EDID compatibility ,.etc
I have also up-gradable notebooks and is impossible without lots mods usage another GPU !
and RTX on older system looks like madness + old CPU .,.TDP mod on PASCAL or RTX
Alienware M17xR3 ? - best try pascal gpu + TDP 150W is ok from MXM ālot users using more - 200Wā and still works good
also this gpu is in best range for yours others HW ,.,benefits from RTX is minimal here
easy app for TDP mod - TDP tweaker ābut need HWflasher + 1.8V adapterā and configure custom TDP in AFTERBURNER .,.and all works nice
if you no need QUATRO ,.,i recommend normal gtx1070 - best for you āgtx1080 need power cableā
Hybrid vBIOSes exist to support older systems that donāt support UEFI, I forget the specifics but essentially the only way to use a vBIOS in legacy mode on a UEFI system is to completely rip out the GOP, which in turn breaks the vBIOS encryption in place to prevent tampering to an extent this was true even for Polaris cards vBIOS mods broke the UEFI support and you had to do a specific fix for that if you didnāt want to run in legacy mode only. Then thereās other stuff with modern GPUs such as the checksum and the possibility of modern Windows systems possibly not even loading the display driver with such vBIOS changes soā¦ good luck breaking the encryption. Theres a reason things like more power tool exist and its not because people lack the knowledge to modify vBIOS and tailor them precisely to their needs among several reasons it is because manufacturers got tired of RMAing cards users ābrokeā and didnāt know how to unbrick them or lacked the ability to do so.
Just for the record, my favourite GPUs of all time because of how much you can customise them and the performance you can get out of them when properly optimised are the Polaris cards, those things are still potent 1080p cards and arenāt too bad at 1440p in a lot of titles still.
This is why ill never part with my Gigabyte X470 Gaming7 WiFi its worked with every GPU ive thrown at it going back to Nvidia 8800GT
I miss Lost n bios, i do hope hes ok.
Sorry I use google translate.
For the needs of the graphics card firmware research, I modified the last two versions of nvflash, mainly modified 7 jumps so that the program will not go to āInvalid firmware image detectedā, because it is an experimental project, it may destroy the function or An unknown situation occurred. Please feedback if there is any situation.

Hi wudimobile,
Iāve tried both nvflash versions, trying to flash Alienwareās 3080ti mobile, but it catches subsystem ID mismatch right at the end.
Any help would be appreciated 
Are you writing to a different model of vbios?
For 30-series, I donāt know what verification has been added at this time, so any modifications to vbios may not pass verification, perhaps using programmer to write to the chip will work.
I canāt offer any more help at the moment.
Did this just bork my GPU? not flaming or blaming anyone, I chose to fiddle with my PC so entirely my doing. Last night I ran ānvflash v5.670.0 patched update3ā with the command nvflash --index 0 rom.rom. And my screen went black immediately which is strange because the first thing NVFlash does is asks to confirm. Iāve booted off a second GPU, flashed the first one again with itās original firmware but it just fails to boot. Even though I can see it fine from GPUZ. Any suggestions appreciated
I think I posted this somewhere in the thread before but as I keep getting emails for passwords the only passwords I have for these archives are;

This is a dead project now it was only ever intended as a proof of concept.
I tried reaching out a few times but nothing. Someone else might know better but I think putting out other peoples fires all the time just got tiring to him, understandable IMO I had to stop saving every individual that shot me a message years ago because it just got too much to stay on top of which is why I now make really detailed guides when I can and just lend a hand here and there to those really struggling
Could you send me the password in a PM?
