I need some help about booting ds3100 (pmax) off cdc wren-v 600 meg scsi disk. We currently have a ds3100 with a dec disk on it and a tk50 cartridge drive. We are getting two ds3100 without disk from dec and two cdc wren-v scsi drives from someone else. My questions are how to format these two disks, and make file systems for the ds3100s and hang them on to these two ds3100 and let them boot from the two cdc drives? Thanks in advance! PS. Please tell me the detail procedures if you can.

I recently installed a ds3100 with a WREN V disk. So I'll report my experiences. It's not easy to get the right cables to connect the disk to the ds3100. So far we are only able to connect the disk via the TK50. But we heard a rumour that DEC sells the right cables. (Our DEC-rep didn't say a word about that. See last 2 lines of this article :-) The Ultrix installation tape does not support third party disks. But this can't stop us. There are ways out: Choose 'System Management' on the first prompt of the installation procedure. Then 'ed install.1'. After the lines RZ55) ns=36;nt=15;; add the lines UNKNOWN) ns=48;nt=15;root_D=WREN;; . Partition the disk as you need it. cd /dev; MAKEDEV rz0 [e.g.] chpt -pa 0 32768 -pb 32768 32768 /dev/rrz0c chpt -pd 65536 32768 -pg 98304 1075626 /dev/rrz0c Then do 'cd /;. .profile'. This restarts the installation. Choose 'Advanced installation' now. In the second phase of the installation (after booting from disk) you have to stop the installation by ^c. Then 'ed /etc/disktab'. Add an entry like WREN|UNKNOWN|CDC WREN V 94181-702 (unknown by DEC finder):\ :ty=winchester:ns#48:nt#15:nc#1543:\ pa#32768:ba#8192:fa#1024:\ . . [ Partitioning information is irrelevant] Then 'cd /; . .profile' I built a customized installation TK50 that does the above. If you want to know how to do this send me mail. I'm now in the process to setup a 'Remote Installation Service' from a VAX for the ds3100. The right way to solve the 'UNKNOWN problem' above would be to teach finder (and also autoconf) to recognize the CDC WREN V. We didn't get Ultrix 3.1 sources yet. So I could not try it. The ds3100,WREN V configuration is running fine now for ca. four weeks. ~~ Matthias Kandler Inst. f.
