RSX-11M/M+ Question

Is there a way to configure either RSX-11M or RSX-11M+ to boot up off of a disk that it can't write to? I just created a backup CD-R of my RSX-11M system, but since it could't write to the disk as it was coming up it didn't come up in a usable state. However, it did boot. Alternatively would it be possible to boot standalone backup off this CD or build a CD with standalone backup? RT-11 is a little more forgiving :^) Though I messed up and didn't have the partitions assigned correctly before making the disk image so I can only access part of my data when booting from CD, still it's enough to be able to recover the system with should I loose the HD!
