Calvin Miracle also noticed that the VAX780 had an issue booting/running NetBSD 6.1.5 with some devices when the system had more than 64MB of memory.

With the latest simh version (and the VMB.EXE it contains) an R5=0 boot will work fine for both NetBSD and Ultrix on all the older VAX models. - Mark _______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
