[cctalk] Ultrix 11 installation and ZULU SCSI Disc Emulator

Hi all, I tried several ways to get a working SCSI image to be successfully boote on a ZULU 2024 SCSI Emulator. 1. I do have an Image of an RZ25-E drive containing RSX11M Plus, which is booting properly. This is a raw dd based disc image of a SCSI drive. 2. I got a disc mage by Jacob, which is booting using simh, but not using the ZULU on a physical 11/73 3. I created a fresh installation of Ultrix 11 using simh 3.9.x creating a RD54 image which won't boot on the ZULU an the physical 11/73 4.. I created a fresh installation of Ultrix 11 using simh 3.9.x directly into a physical SCSI drive partition, created an image via dd which doesn't want to boot on the ZULU. Simh is booting properly from a dd image of this partition. 5. Simh is telling me in general using a (virtual) RQDX3 controller. Maybe the images created won't boot because of being created by the virtual RQDX 3 controller? How to create a raw disc w/o any controller specific format - simply a plain Ultrix 11 image as a target for a SCSI drive to be booted either from the physical, or from a virtual (ZULU). Best Andreas
