Right now we're running BSD4.1 on a VAX-11/780. We just received our 785 upgrade kit. We want to swap in the new CPU boards next weekend to help our swamped out 780. From following the discussions about the 785 being bug-for-bug compatible with the 780, I know that 4.2 runs on the 785, whether it's 4.2 from the Berkeley distribution or from an Ultrix distribution. I'd like to be as confident about 4.1, too. Has anyone run 4.1 on a 785? Since we want to make the switch, reboot, and start running (faster) without any interruption, I'd like to ask if there are any potential trouble spots to look out for. In particular: will the instructions in "Installing and Operating BSD4.1" for making a new boot floppy be enough? Any hidden trickiness with the 785 on that score? Are there any drivers or even any kernel code which might be sensitive to timing changes that a ~50% boost in CPU speed would bring out? Please, no flames about 4.1--we'll be going to 4.2 soon.
