In the next month or so I will be installing Berkeley 4.3 on a uvax. The first problem I'm going to have is to get a generic system to boot from a tk50 (the tape drive) I would like to contact anyone who has installed 4.3 (or 4.2 will do) on a uvax and has made a bootable system on the tk50?

The easiest way to get 4.3 onto a uVAX is to get Ultrix up first, then use it to bootstrap 4.3. Note that 4.3 supports the uVAX II, but not the uVAX I. It also helps to have a VAX already running 4.3. A set of bootstrapping floppies comes with Ultrix. Once Ultrix is up, you can ship 4.3 over across your Ethernet and boot the new system. One must be a little bit careful in bootstrapping; 4.3 and Ultrix are not quite compatible and if you screw up the machine may hang and you must reload Ultrix from floppies and start over. (e.g. a 4.3 kernel doesn't much care for the Ultrix init). It would be wise to backup any user files before you begin. Here are (roughly..its been 6 months since i did this) the steps: 1) get Ultrix up 2) On the root partition, create /bin.43 and /etc.43 and rdist over those directories from a 4.3 (VAX) machine. Also, get /usr/bin.43 over in a similar manner. If your root partition is too small to have both the new and old copies of the directories, you will have to get some more space. You can probably find files in /etc and /bin that are not critcal. For instance, cut down the size of the host table, get rid of /etc/dump*, etc. NOTE, the 4.3 rdist thinks that rdist is in /usr/ucb on all machines. On non 4.3 machines, it is in /usr/local (or /usr/local/bin). On the Ultrix machine, mv or link rdist into /usr/ucb before attempting to rdist. 3) Get a 4.3 kernel onto the uVAX. Be sure that it has been compiled with the VAX630 option. I don't believe it is in the generic kernel that comes with the 4.3 distribution. 4) Fix up the rc.local, fstab, and ttys file in /etc.43 for your machine's configuration. 5) Take that plunge! That is, issue the following commands and boot the 4.3 kernel. This is the point of no return. Once you have issued *some* of these comands, or the machine gets rebooted or crashes, your machine may hang. mv /etc /etc.ultrix mv /etc.43 /etc mv /bin /bin.ultrix /bin.ultrix/mv /bin.43 /bin mv /usr/bin /usr/bin.ultrix mv /usr/bin.43 /usr/bin mv /vmunix /vmunix.ultrix mv /vmunix.43 /vmunix /etc/reboot 6) Not all the major device numbers are the same in Ultrix/4.3. You may have to delete entries in /dev and use the 4.3 MAKEDEV to put them back in correctly. I know that the numbers for the DHV-11 are different. They were the same for the RD-52 and DEQNA though. 7) You should now have 4.3 up. You still need to get the rest of 4.3 over. Again, rdist comes in real handy. you can rdist /lib /usr/local/*, etc. -- Thomas Narten narten@purdue.EDU or {ucbvax, ihnp4, allegra}!purdue!narten
