What does one have to do (Linux, MacOS, *BSD) to write such an image to the CD with
512-byte blocks, so it can be read by a DEC boot-ROM?
I think that's a property of the CD drive, not the disk itself.
I've got a Plextor CD writer which can be jumpered between 2048 and 512
I was able to boot the Ultrix installation CD (MIPS) on a DECServer.
