DEC VX40 Multia	by Bill Degnan - 05/14/2017 10:17
This tiny (~10 inches wide) DEC VX40 Multia stared out as a VX40B and was field upgraded to a VX40L-F2 . Click image to see files Boots up like a typical Alpha from the mid 90's. This system has VMUNIX installed but I have not yet cracked it to get access. Click image to see larger view. See boot screen succession snapshots. If you the reader have experience with this hardware or have any comments please contact me. More to come. Reply
DEC UNIX 4 hacking for Root Access	by Bill Degnan - 10/28/2017 12:48
The DEC UNIX CDE Desktop. Click image for larger view. I was able to change the DEC UNIX 4 root password as follows: >>> b dka0 [enter] # mount -u / # mount /usr # passwd (enter new password 2X. ) HINT: Use a complex password with Upper/Lower/special chars/numbers in the event the system requires complex passwords. Even if you can change the password X Windows might not let you in. I found that in this systems' case the OK button is be greyed out when the password stored in the passwd file does not conform to the rules. Restart your system. -------------------- In this particular Multia running DEC UNIX 4 here is what I have to do to get into the DEC GUI known as the Common Desktop Environment (CDE), EXACTLY, from a cold boot (assume you hit enter after each line): >>> b dka0 # init 3 This initiates the startup script for single user CDE session. Because I am not connected to anything and the system has not been configured the system freezes trying to connect to the network for an update (watch for when the line "Update: started" prints on the screen). To bypass I hit CTRL+C. Once the startup script finishes the system asks me to log in. Upon successful login I am greeted with a # prompt again. To enter the CDE I enter these commands: # ./xlogin stop # ./xlogin start (why I can't use restart I don't know) Finally, I get to the CDE GUI login screen prompts. NOTE: If you have issues check /etc/securettys for lines that contain references to :0 in them (meaning root display ":0" can login locally). Useful page: http://bhami.com/rosetta.html Reply

>>> b dka0 # init 3 -log in- #cd /sbin/init.d/ # ./xlogin start login once the GUI boots up. Reply
