It is something that crossed my mind and I have not checked. I think this
will have to be my next line of investigation.
Thanks

It is failing at the stage of detecting the
disks with an
"invalid block size" error.
I am using a CR-506 CD-ROM drive and the disks I have are RZ56 and RZ57.
Could this be an issue with the CD-ROM not supporting 512byte blocks?
I know that microVAXen need this to install VMS, perhaps this is true with also.
With some drives you have to set a jumper to force it to 512byte blocks.
