I don't have a copy here at the moment, but I can repost it from home. I'd be happy to see it (or something based on it) become a part of the standard NetBSD distribution, and integrated into the install kit for NetBSD/vax... It was re-engineered from the tables in the back of one of the VMS 5.2 manuals -- and I interestingly uncovered several small mistakes in those tables while doing it. :-) (My program agrees with the actual CONFIGURE output where the tables don't.) Anyway, the actual CSR and vector assignments generally depend on the total configuration of the system, but here's a simple run on a VAX, based on what you asked about: $ MCR SYSGEN SYSGEN> CONFIGURE DEVICE> UDA,3 DEVICE> ^Z Device: UDA Name: PUA CSR: 772150 Vector: 154 Support: yes Device: UDA Name: PUB CSR: 760334* Vector: 300* Support: yes Device: UDA Name: PUC CSR: 760340* Vector: 304* Support: yes SYSGEN> -tih -- Popularity is the hallmark of mediocrity. --Niles Crane, "Frasier"
