## vBIOS
I experienced some weird things when doing this on the display, like a corruption of the image, but seems to work fine. If you encounter anything, a reboot solved my problems.

### Method 1 - Linux
It did not work for me, the ROM is 59KiB and it should be around 162KiB. It may work for you.
1. Execute `scripts/iommu.sh` as **root** to get the BUS ID for the GPU. Looks like `0000:06:00.0`.
2. Edit `scripts/extract-vbios-linux.sh` to your convenience. Change `videobusid=`. [Optional] Change also the location where the vBIOS will be save `VBIOS=`.

From here you are alone, I don't know how to proceed. Maybe you need to edit, maybe don't.
### Method 2 nvflash in Linux
### Method 2 - nvflash in Linux
1. Download nvflash https://www.techpowerup.com/download/nvidia-nvflash/. Do not install from AUR; the package it's broken.
2. Unzip it as `/root/nvflash_linux` with `# unzip nvflash_5.414.0_linux.zip -d /root/`
3. Edit `scripts/extract-vbios-nvflash.sh`. Change `videobusid` with your GPU; `NVFLASH=` if you changed the location of the executable; and `VBIOS=` if you want the ROM in other place.
4. Link the service to systemd: `ln -s scripts/qemu@.service /usr/lib/systemd/system/`
5. Execute the systemd unit with `sudo systemctl start qemu@extract-vbios-nvflash.service`. You can also do it over `ssh`. The extracted ROM will be in the root directory `/root/vBIOS.rom`
6. [Edit the vBIOS](#edit-the-vbios)
### Method 3 Windows
Get the GPU BIOS [Source](https://www.youtube.com/watch?v=1IP-h9IKof0). [You can download the bios from techpowerup.com](https://www.techpowerup.com/vgabios/); if you do so, download a HEX editor and skip to step 5.
