I've ran dd if=NV287MH.2K0 of=strip bs=1 skip=1536, put the ROM file in /usr/share/qemu, run restorecon on it and it started working! I'm so thankful for both of you Alex and Thomas, i've been trying to get it to work for at least 4-5 days and you've helped me in just one day. While we are still here, do you have any recommendations on optimizing the VM so it runs smoothly almost as a native OS and how should i interact with the VM? I've seen an article on https://rokups.github.io/blog/#!pages/kvm-hid.md that made a software KVM switch, would that be good?
