I was following this guide on how to do single gpu passthrough, I reached the vBIOS Patching section and ran this code:
echo 1 | sudo tee /sys/bus/pci/devices/0000:01:00.0/rom
sudo cat /sys/bus/pci/devices/0000:01:00.0/rom > path/to/dump/vbios.rom
echo 0 | sudo tee /sys/bus/pci/devices/0000:01:00.0/rom
Got an Input/Output error so I tried to run it in recovery mode and still got the same output:
root@wanka-GL703VM:~# echo 1 | sudo tee /sys/bus/pci/devices/0000\:01\:00.0/rom
1
root@wanka-GL703VM:~# sudo cat /sys/bus/pci/devices/0000\:01\:00.0/rom > /home/wanka/vbios.rom
cat: '/sys/bus/pci/devices/0000\:01\:00.0/rom': Input/output error
root@wanka-GL703VM:~# echo 0 | sudo tee /sys/bus/pci/devices/0000\:01\:00.0/rom
0
When running sudo dmesg | grep 0000:01:00.0 I get this:
wanka@wanka-GL703VM:~$ sudo dmesg | grep 0000:01:00.0
