OK, trap 6 code 2 is integer divide by zero on the VAX. My obvious guess is that the disk has a garbage label on it and when the kernel tries to interpret it, it divides by zero and blows up. A garbage label is something worse than no label at all, because the label structure has a magic at the beginning, and trust me, the kernel does check it and it does not blow up with a divide by zero when block 0 is all zeros. Wilko, what exactly do you have in the label block of disk 1? If you've been following my installation instructions to the letter, that disk would be your Ultrix disk. My installation instructions call for labeling the BSD disk, but not the Ultrix disk. In fact, putting a BSD label on an Ultrix bootable disk would render it unbootable, as Ultrix has boot code where BSD has the label. This means that normally when someone follows my Ultrix-based installation procedure, BSD will simply view the Ultrix disk as unlabeled and make it one big partition a. You obviously have something else in there. Well, this at least means that this is not yet another one of my own bugs, so that's the good news. :-) But sure, the kernel could do with a few more label sanity checks so that it prints a nice error message instead of blowing up. I'll look into it. -- Michael Sokolov Special Agent International Free Computing Task Force Harhan Computer Operation Facility ARPA Internet SMTP mail: msokolov(a)baryon.trailing-edge.com Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id NAA47798 for pups-liszt; Sat, 28 Aug 1999 13:58:50 +1000 (EST) Received: from henry.cs.adfa.edu.au (henry.cs.adfa.edu.au [131.236.21.158]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id NAA47794 for <pups(a)minnie.cs.adfa.edu.au>au>; Sat, 28 Aug 1999 13:58:44 +1000 (EST) Received: (from wkt@localhost) by henry.cs.adfa.edu.au (8.9.2/8.9.1) id NAA06231 for pups(a)minnie.cs.adfa.edu.au; Sat, 28 Aug 1999 13:58:44 +1000 (EST) (envelope-from wkt) From: Warren Toomey <wkt(a)henry.cs.adfa.edu.au> Message-Id: <199908280358.NAA06231(a)henry.cs.adfa.edu.au> Subject: dmr's comments on releasing old code To: pups(a)minnie.cs.adfa.edu.au (Unix Heritage Society) Date: Sat, 28 Aug 1999 13:58:44 +1000 (EST) Reply-To: wkt(a)cs.adfa.edu.au X-Mailer: ELM [version 2.4ME+ PL43 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-pups(a)minnie.cs.adfa.edu.au Precedence: bulk All, Dennis Ritchie just emailed me with a URL about Dan Bricklin's efforts to release his original VisiCalc: http://www.bricklin.com/history/vcpostingreactions.htm The URL contains a link to an email from Dennis about his attempts to get the older UNIX source code, and the primeval C compilers, released: http://www.bricklin.com/history/dmrletter.htm Cheers, Warren Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id OAA47821 for pups-liszt; Sat, 28 Aug 1999 14:03:48 +1000 (EST) Received: from gull.prod.itd.earthlink.net (gull.prod.itd.earthlink.net [207.217.121.85]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id OAA47817 for <pups(a)minnie.cs.adfa.oz.au>au>; Sat, 28 Aug 1999 14:03:41 +1000 (EST) Received: from gort (1Cust102.tnt2.covina.ca.da.uu.net [208.254.25.102]) by gull.prod.itd.earthlink.net (8.9.3/8.9.3) with SMTP id VAA13229 for <pups(a)minnie.cs.adfa.oz.au>au>; Fri, 27 Aug 1999 21:03:30 -0700 (PDT) Date: Fri, 27 Aug 1999 21:03:30 -0700 (PDT) Message-Id: <199908280403.VAA13229(a)gull.prod.itd.earthlink.net> X-Sender: mjcrehan(a)earthlink.net X-Mailer: Windows Eudora Light Version 1.5.2 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: pups(a)minnie.cs.adfa.oz.au From: Martin Crehan <mjcrehan(a)earthlink.net> Subject: Dennis Ritchie letter on releasing early Unix Sender: owner-pups(a)minnie.cs.adfa.edu.au Precedence: bulk I ran across an interesting account from Dennis Ritchie on the process he went through to get us the SCO liscense for Ancient Unix: http://www.bricklin.com/history/dmrletter.htm Martin Crehan 9 PM PDT, August 27, 1999 mjcrehan(a)earthlink.net Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id VAA49114 for pups-liszt; Sat, 28 Aug 1999 21:08:36 +1000 (EST) Received: from henry.cs.adfa.edu.au (henry.cs.adfa.edu.au [131.236.21.158]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id VAA49110 for <pups(a)minnie.cs.adfa.edu.au>au>; Sat, 28 Aug 1999 21:08:29 +1000 (EST) Received: (from wkt@localhost) by henry.cs.adfa.edu.au (8.9.2/8.9.1) id VAA07821 for pups(a)minnie.cs.adfa.edu.au; Sat, 28 Aug 1999 21:08:29 +1000 (EST) (envelope-from wkt) From: Warren Toomey <wkt(a)henry.cs.adfa.edu.au> Message-Id: <199908281108.VAA07821(a)henry.cs.adfa.edu.au> Subject: Primeval C compilers To: pups(a)minnie.cs.adfa.edu.au (Unix Heritage Society) Date: Sat, 28 Aug 1999 21:08:29 +1000 (EST) Reply-To: wkt(a)cs.adfa.edu.au X-Mailer: ELM [version 2.4ME+ PL43 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-pups(a)minnie.cs.adfa.edu.au Precedence: bulk Hi all, I also asked Dennis if we could put his two old `primeval' C compilers into the archive. He said: I don't have a problem with copying the compilers, more or less as a mirror. I wonder if anyone will try to revive them? I've had a go at reviving them today, using V5 cc and tools. It's a real PITA I can assure you. I've got the last1120c compiler compiled, but I can't get it to compile itself. As soon as it sees line 16 in c00.c i = namsiz; it complains that the LHS isn't an Lvalue. I think I'll stop now, my brain is hurting too much :-) Ciao, Warren Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id CAA50367 for pups-liszt; Sun, 29 Aug 1999 02:46:23 +1000 (EST)
