6. Get the GPU BIOS [Source](GPU_BIOS_video) [Why?][]
[You can download the bios.](techpowerup vgabios) If you do so, download a HEX editor and skip to step 4.
1. Boot the host into Windows.
2. [Download and install GPU-Z][GPU-Z].
3. [Download and install a HEX editor][bless].
3. Open GPU-Z and backup the GPU BIOS. Right next to the `Bios Version`; in my case `80.04.C3.00.0F`, there is an icon for backup. A file named `GK104.rom` will be created. [There is also a way of doing it in Linux][] but it did not work for me.
4. Open the ROM (`GK104.rom`) in the HEX editor.
5. After a bunch of `00` there is a `55` or `U` in HEX, delete everything before the `55`, and save. I strongly recommend not to overwrite the original ROM.

And you must supply QEMU with the Full GPU's ROM extracted extracted using a tool called "nvagetbios" , which you can find in a package called "envytools"
