4090/4080 eDP DP_D vBIOS MOD

[ssj92]

@Tetsu @DynamiteZerg @SuperMG

 

I made a vBIOS mod for RTX 4090/4080 based on the 4070 MXM card. There's a 99% chance it won't work due to falcon but who knows??

 

Anyways simply put, 4070 has eDP on DP_D whereas 4080/4090 has eDP on DP_B.

 

I simply modified the DCB table to match the 4070.

Thanks.

 

But What, so their datasheets were right??? It said eDP on B I was like no way...

 

I have the datasheet of the RTX 4060 and it says eDP on D.

 

I don't have them with me right now.

 

X-Vsion answers about DP_D issue:

 

We encountered a factory with H610 motherboards that had this phenomenon, but later the BIOS PCIE was set to ASMP Disabled and they could be used 

 

MSI B760M-P open UEFI and CSM OK

 

Z690 no

 

Asrock B550 open UEFI and CSM OK

 

ASUS H610 Some models work, some models don't

 

I also sent them your Google drive link so they can test it and maybe... Find someone to certificate them?

I don't know who you are talking to , but might be useful to CC me on the email chain. The more information I have from them the easier it is to do mods

Jason from X-Vsion. Helen doesn't answer to emails anymore. Jason gave me more informations than Helen did in a 1 year...

Jason from X-Vsion told me something interesting.

 

Their early version of the 4080 and 4090 (black PCB with some capacitors on the X-bracket way) have full eDP support on D. It used some Clevo VBIOS that I can't find.

 

@janepahas the Black PCB version.

[SuperMG]

@ssj92

Got it https://drive.google.com/file/d/1Xt0R8L33k5xgRKVUs2Kbt54Da6Ra5Kf_/view?usp=drivesdk

 

This is the early version of the 4090 VBIOS. 

 

Could you tell us if the DCB is different than the latest 4090 VBIOS? VBIOS version number? Can't check because I have no computers there, can only be available in 4-5 days 😞Thanks

DP_B on that vbios so maybe this is the wrong vbios. 95.03.3E.00.16

I have that 4090, need to figure out x-bracket issue. Also it had a 4090 ASUS mobile ROM which caused 6 beeps.

The VBIOS comes from a Clevo X370SN. You sure the eDP is not in D? Then this is so strange.

 

What's that Asus VBIOS? Same DCB? Same GPUID?

Yes I am sure. 
 

my 4090 had this ASUS bios.

Alright.

 

I told X-VSION to sign your modded VBIOSes. I am sure they have a contact since they are a big company manufacturing lots of embedded GPUs.

Okay let’s see if they can sign it

You changed everything related to DCB correct? Then it'll be easier for them. I told them how you did the vbios mod (4070 DCB to 4090 DCB) if they can't sign yours.

I just got RTX 5000 working on my M17xR3 eDP PEG last night pure legacy and now I’m working on 4090 with built in bios backlight pin mod (no flex cable needed). 
 

you still doubt me? The 4090 vBIOS is correct

Because there's the DCB virtual table and then there is also a connector table that details the interfaces. Did you edit them as well? That's what JadeRover told me in order to edit every DP_ outputs.

 

I hope to sell all of my backlight mod v2 because it works on my M17X R4 with the A5500 and RTX 4070 in pure UEFI

I edited all the legacy ROMs not just the first one. Either way nothing is guaranteed until we have a signed vBIOS. Only then can we do testing. I made 400 bios’ to make RTX 5000 working, it wasn’t done in one shot. 
 

if 4070 is working , 4090 should work too IF the vBIOS is properly signed. The complete eDP path was ported over.

4050-4070 is the best card for DCB. Works with DP_A/DP_B/DP_C/DP_D.

 

M4800, M6800, 7720, P870, all the outputs worked! With the backlight mod v1/v2

 

The ampere ones are fine but DP_B is HDMI and not DP...

[SuperMG]

Now I understand why ZRT were ignoring me, their datasheet were fake lol...

 

ZRT 4080/4090 had the same "display tables" as the RTX 4050/4060/4070 but that's not true.

 

So I wasted like 8 months for nothing lol.

 

If X-VSION can find someone who can sign your modded VBIOS it's so good. It'll fix everything and I'll donate you 40€ if they do it.

Honestly if they can sign that vBIOS then they know someone in nVIDIA or they have a leaked tool. Which is good for us because we can make more vBIOS mods 

 

all modern 4090 have DP_A or DP_B for eDP. I checked like 15 vBIOS’

That's news for me.

 

If we could just get basic DP for B and D, it'll be good for us still. Because basic DP works on eDP screens as I tested with many laptops and with many Ampere cards from X-VSION.

 

I thought they were still doing eDP on DP_D... The Clevo P870, X170 and HP ZBook G6 are using DP_D for eDP too...
