FreeDOS VM Issues

I am looking to set up a FreeDOS VM with networking and CDRom support. I recognize I will be things I shouldn’t (such as using the incus CLI).

To get it to boot, I had to set security.csm: "true". Doing a quick search, incus does not permit you to specify the network device. I tried to set raw.qemu="-vnc :10 -net nic,model=ne2k_pci", but that gives me a PCI conflict when I start the VM.

Has anyone tried this and gotten it to work?
