I'm happy to share it out, though it's not too hard to do manually -- there's a writeup at https://minnie.tuhs.org/Archive/Distributions/DEC/Ultrix-11/Fred-Ultrix3/setup-3.1.txt that covers the basics. > Glad to to hear you were able to get this running with the EIS, I was > unsure if it was possible.

Ultrix runs fine, but it's tight and the lack of separate I+D spaces means some programs won't fit (vi, for example). I did manage to build a kernel with TCP/IP and Ethernet included, but I need the larger backplane in order to install the Ethernet controller to test it :). > > I will check to see if I have the backplane. > Thanks! - Josh > > Bill Degnan > >
