The Question is: We have attempted to install a KZQSA SCSI board into our VAX 400-500 system running VMS 5.5-2H4. Due to a custom interface board currently installed, we are running into CSR conflicts and I am seeking answers to the following questions. I am looking for the jumper settings and resulting CSR values for the W1 thru W7 jumpers on a KZQSA SCSI controller board. Can multiple jumpers be installed or is movement of a single jumper the limiting factor? Where could I purchase or download the KZQSA installation Guide (Part# EK-KZQSA-IG)? We have had no luck in locating a copy. Thank you, T.J. The Answer is : Please contact your hardware services organization, or the Assisted Services program referenced in the OpenVMS FAQ; please see topic (1202) and (2648), among others, in addition to the Assisted Services program information in the FAQ. For information on the Q-bus, please see topics here including (1149), (1866) and (3232). You will want to configure the ENTIRE Q-bus, as the ENTIRE Q-bus -- all Q-bus devices present, all devices to be removed, and all devices to be added -- must be considered when performing a Q-bus bus reconfiguration. (Q-bus devices cannot be and are not configured in isolation. Configuration changes for the CSR and/or the interrupt vector can and often do involve more than one Q-bus module.) The OpenVMS Wizard would supplement this VAX 4000 series Q-bus system with a newer SCSI-based system; with a VAX or an Alpha system with a native SCSI connection. The OpenVMS Wizard would not attempt to use a KZQSA for more than it is (was) supported and tested with; with devices other than specific tape drives and CD-ROM drives. The KZQSA is not intended as nor suitable as a generic SCSI interface for Q-bus systems.
