NiPoGi Model E3B - ReBar enabled according to GPU-Z, but Intel Software says nope, BIOS with FFS added included

[dreimer1986]

Hello, first some details:
The PC is a Mini PC from NiPoGi and it's the Model E3B with a Ryzen 5 7430U and a AMI BIOS that seems to be based on Aptio V (at least the flash tool worked for Backup and Flash).

I am using a M2 to Oculink Adapter and then a Oculink to PCIx adapter, too. On that I hooked my Intel Arc B580

Things work quite fine... if you ignore the missing ReBar by default. So I dumped my BIOS, added the FFS module and set the ReBar size to 2^10 with ReBarState.exe. Anything higher causes the system to not boot anymore unless I unplug the card and change the size with the onboard one back to max 1G. The Patcher does not allow ANY patch to be applied and I guess this is my problem in the end? 1G ReBar size might be not enough to make Intel enable it on 12 G vRAM? GPU-Z says all is super fine, but Intel Software says it could not be any worse than it's right now...

I added my BIOS below, too. Maybe someone can help me with the patching and maybe look if I did some mistake? I verified that the module was flashed btw, I did another dump after the flash and it included the FFS module.

I would really appreciate it if someone cold check the file and maybe find the correct patches for this BIOS to allow more ReBar size or Rebar at all? Btw, 4G decoding can be fould as hidden function, but GPU-Z says it's enabled already anyways.

All in all I don't understand whats going on at all. Some ppl say that enabled ReBar means that you find some large memory range in device manager, too. I don't have that, either...

@dreimer1986 do you have your original dump? would you also tell (and elaborate) the modded bios flashing procedure? this might be helpful for those in mobile devices or maybe even on desktop where bios flashback feature is not available.

OK, first some news regarding that matter. Even though GPU-Z claims that 4G decoding is active it was not really as it seems. The added FFS file did a nice job with what it was able to get without the 4G decoding aka max 1GB of ReBar size. This is not enough for the Intel GPU to activate it as it seems. I was able to get a modded BIOS with all hidden stuff enabled from the guys over at https://winraid.level1techs.com/ and there I was able to switch on 4G decoding AND ReBar and now all is super fine. But I killed my PC, too as this BIOS has dangerous features editable, too... and in my curiosity and stupidity tinkered a bit too much with these... As new BIOSes are not CMOS anymore, I was not able to reset it back to default anymore. Luckily warranty was still granted and I replaced the PC even though I told them what I did. Looks like sometimes telling the truth is better than lying. So if anyone ever needs a small PC with good price and EXCELLENT support... Check for NiPoGi :D I had way worse experience with BIOS problems in the past (one even resulted in a camera team showing up at my house to interview me ^^) and these guys just told me all is fine and send it back.

Sooo, if anyone still wants the original OR the modded BIOS I can add it here of course. But this one does not need the FFS anymore as it's now able to enable ReBar on it's own.

Ah and regarding how I did the flashing:

This official Aptio V flasher worked super fine for getting a full dump AND flashing the modded BIOS. I can upload this one, too if wanted.

Here some photos with results AND all the billion now available settings: https://photos.app.goo.gl/dhJU51hN3zhwBHkw8

I can't provide a picture from work, but there is a option on the left. Something like flash all or something. I just select this one and the rest I keep default.

@dreimer1986 Which one of these?

[dreimer1986]

Program all Blocks

Thank you @dreimer1986 , but i've stumbled upon this AFTER flashing, not before flashing:

I modded/inserted the .ffs to the bios only, did you also stumble upon it too?

[dreimer1986]

Nope. It did never output any error for me. Not with the FFS and not with the completely modded BIOS. Did the verification succeed aka did all block get green?
