Unable to dump

Script location: /tmp/user.scripts/tmpScripts/Dump_GPU_vBIOS/script
Note that closing this window will abort the execution of this script
You have selected this device to dump the vbios from
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Lexa XT [Radeon PRO WX 2100]
This does look like a valid GPU to me. Continuing .........
Checking if location to put vbios file exists
Vbios folder created at
mkdir: created directory '/mnt/user/isos/vbios/'
I will try and dump the vbios without disconnecting and reconnecting the GPU
This normally only works if the GPU is NOT the Primary or the only GPU
I will check the vbios at the end. If it seems wrong I will then retry after disconnecting the GPU
Defining temp vm with gpu attached
Domain dumpvbios defined from /tmp/dumpvbios.xml
Starting the temp vm to allow dump
Domain dumpvbios started
Waiting for a few seconds .....
Stopping the temp vm
Domain dumpvbios destroyed
Removing the temp vm
Domain dumpvbios has been undefined
Okay dumping vbios file named WX-2100.rom to the location /mnt/user/isos/vbios/
cat: rom: Input/output error
Um.... somethings gone wrong and I couldn't dump the vbios for some reason
Sometimes when this happens all we need to do to fix this is 'stub' or 'bind to the vfio' the gpu and reboot the server
This can be done in Unraid 6.8.3 with the use of the vfio config plugin or if you are on Unraid 6.9 or above it can be done
directly from the gui in Tools/System Devices .....So please do this and run the script again
In this case, this GPU is not the primary but is in slot 1. The system has an AMD APU and another undetected GPU in slot 2.
I actually already have the appropriate PCIe devices bound to vfio as well so I'm not sure why the output suggests otherwise.

There's a variable on line 49 called forecereset. Try changing it from no to yes and see if that helps.
I was having the same issue and this fixed it for me.
I tried that and it gets this far but never continues. File is created but it's zero bytes.
