Our emails are crossing each other unfortunately, but I want to
reinforce this: ring memory is not write protected. Remember that
SeaBIOS can even provide virtio-scsi access to DOS, so you must
not reset the device. It must remain functional all the time,
and the OS's own driver will reset it when it's started.
