I've assembled some notes from old manuals and other sources on the formats used for on-disk file systems through the Seventh Edition: http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html Additional notes, comments on style, and whatnot are welcome. (It may be sensible to send anything in the last two categories directly to me, rather than to the whole list.)

Re: non-broken 4.3BSD set?

by Warren Toomey

In article by Robertdkeys(a)aol.com: > Warren... is there a non-broken 4.3BSD-Tahoe set somewhere? > Bob As in a bootable 4.3BSD-Tahoe kit? As far as I know, no. The Unix Archive has a broken copy in 4BSD/Distributions/4.3BSD-Tahoe, indicating that both usr.tar and src.tar are broken. It might/should be possible to merge files from the CRSG CD set from Kirk to recreate these tar files. Anybody out there have an unbroken Tahoe release? Warren

Yes, it does. A bug in the parsing. Why it does not affect all the lines is unknown. Perhaps some trailing whitespace caused the parser to exhibit the bug. > But if I try to use /dev/ttyl1 I get a message about a unknown interrupt > and the output of /dev/ttyl1 hangs after the first character. What is the exact message? I did a "strings /unix" and could not not find a string that looked mentioned unknown or interrupt. That would seem to indicate that the device is interrupting but not at the expected vector. It is possible to use 'adb' to look at the contents of the vectors. adb -k /unix /dev/kmem 0344/o will show the contents of the 0344 vector. The value there should be equal to 'cnrint' (or cnxint - I forget which comes first). > I have a M3106 DZQ11 that I can use instead.

I am really not used to Unix stuff of that age. :) I did the the same thing - wondered why I could never get a clean file system. Then I realized what was going on. Cheers, Steven Schultz

I do not recall any particular problem getting additional DL devices recognized (the 11/93 had 7 of them). Seeing the 'no address found' error is *strange* though - that would indicate that 'autoconfig' could not find 'cnrint' or 'cnxint' in the /unix symbol table. Look at /sys/autoconfig and you can see where that message is coming from. If you do nm /unix | egrep 'cnxint|cnrint' what do you see? > NKL 4 # KL11, DL11 > The card has four ports, one of them is the console. (The M8192 CPU card > has no SLU / ROM / ...) Ah, ok. My 11/73 has a SLU/ROM card and the console is on that. I also have a DHV installed (alas, the system is powered down now so I can not check for more information). > But I would prefere to get the DHV11 working. It seams that this device > is more suitable for multi user operation. Yes, it's a little better. Not as nice as a DHQ-11 though (which can run in DHU or DHV modes - with DHU mode having much better silo handling). I forget the exact error you were getting on the DHV but if it was 'no interrupt' then it might be that the DHV clone is not behaving exactly like a DEC DHV In /sys/autoconfig/dhvauto.c here is how the probing attempts to force an interrupt: dhvprobe(addr,vector) struct dhvdevice *addr; int vector; { if ( grab ( &(addr->dhvcsr) ) & DHV_CS_MCLR ) DELAY(35000L); if ( grab ( &(addr->dhvcsr) ) & (DHV_CS_MCLR|DHV_CS_DFAIL) ) return ( 0 ); stuff ( DHV_CS_RI | DHV_CS_RIE, &(addr->dhvcsr) ); DELAY(3500L); stuff ( 0, &(addr->dhvcsr) ); return(ACP_IFINTR); } Either 3500 microseconds (very approximately of course) is too short of a wait _or_ the method of trying to generate an interrupt is not correct. You can try changing 'ACP_IFINTR' to 'ACP_EXISTS' which tells autoconf to not care if the device interrupted or not. > ** Last Mounted on / > ** Root file system > ** Phase 1 - Check Blocks and Sizes > ** Phase 2 - Check Pathnames > ** Phase 3 - Check Connectivity > ** Phase 4 - Check Reference Counts > ** Phase 5 - Check Free List > BLK(S) MISSING > SALVAGE? y > > ** Phase 6 - Salvage Free List > 1364 files, 11625 used, 2430 free > > ***** FILE SYSTEM WAS MODIFIED ***** > > But on the next reboot I get the same when running fsck. Any hints? How are you rebooting? With the "reboot" command or by using the 'halt' button? You do not want to use the 'reboot' command because that does a "sync" which flushes the disc cache (and superblock) back out to disc - that overwrites the work that 'fsck' did. A few 'missing' blocks is not a serious problem though and can be ignored. Cheers, Steven Schultz

Re: [pups] 2.11BSD device config trouble

I don't think that's the problem in this case - the error that is being printed out: cn 1 csr 176540 vector 344 no address found for kl/dl-11 comes from what appears to be a missing entry (or an entry that autoconfig can't find) in the /unix kernel symbol table. One way, I think, this can happen is when booting an alternate kernel (/genunix instead of /unix). THe only suggestion I have at this point is to turn on debugging in autoconfig. To do this go into /sys/autoconfig/main.c and add a line that forces 'debug = 1;', then install (after saving the original ;)) autoconfig into /etc and reboot. Hopefully useful info about what autoconfig is doing will be printed. > Mine is at least correctly identified by autoconfig, though I've never > attached a terminal to it to see whether the ports actually do anything. > The post that's vanished included my dhv line from /etc/dtab but, except > for the goofy CSR I used for some reason that I cannot now remember, it If I find the time I'll power up the 11/73 and see what it says but I've had a DHV11 on the system for years (it's how I got the RTS/CTS flow control working). My suspicion is that the DHV clone isn't behaving 100% like a DEC DHV card. > > BTW: Never play with the SMD cables when the machine is running. Now I > > get: > > Is the disk write-inhibited? Doing a 'reboot' (which performs a sync(2) call) will overwrite what fsck has done - when the message about "reboot" comes out you should use the front panel or ODT to simply halt the cpu and then start the boot process cold.

cross reference tool for pre-K&R C

by nao

Hi, I really enjoy hacking ancient unix rather seriously and want a cross reference tools for them. Since some of them are written in pre-K&R C, modern tools are not very useful. Is there any cross reference tool for pre-K&R C source codes? BTW, early UNIX assembler document has bugs which state '>>' and '<<' are shift operators despite that really '\>' and '\<' are. I wonder where these bugs came from... Cheers, - nao

Who were you talking to at the NetBSD > project? Hi Greg. I am worried with possible licensing issues with AT&T's Documenter's Workbench (DWB). In fact, AT&T retained the copyright and distribution rights on those parts of the UNIX documentation tools they developed some years ago. That is the reason we have [nt]roff, but not diction (diction(1), explain(1), suggest(1)) and style(1). Last days, Perry E. Metzger observed that 2.11BSD was closed source: "And it is closed source. Sorry. We aren't allowed to use code that did not originate in V7/32V. If Caldera did not specifically release the sources, we cannot use them. If your claim is that diction and style were not in 32V, then we have no rights to them." Well, in a previous email Perry observed that: "I appreciate all this and I thank you for doing the work, but please do your work against a version we have clear ability to use." In short, he does not says that "we cannot add diction(1) and style(1) to NetBSD" only that *license terms are NOT clear*. What I do *not* want to do, is asking for adding a piece of code that will report problems to the NetBSD Foundation. They are doing a superb job, and I do not want to start a legal problem adding some tools whose license is not clear. On the other hand, Steven M. Schultz observed that "Not 100% - much of it is covered by the BSD license and the Caldera/SCO/whatever license(s)". I believe that diction(1) and style(1) are covered by a different license agreement, but I did not find it in the source code. > > Can someone, please, helping me on this matter?

Caldera (now SCO again) was supposed to make some kind > of official statement, but it's taking its time. Well, there are some operating systems under Caldera's agreement (a BSD-style license), including v7 and 32V, but looks like 2.11BSD is *not* under those terms. In fact, it is not available through Caldera, it is in tuhs, not covered by Caldera's license agreement. (at least I think that it is right...) I am not a lawyer, only a Physics grad student working on a Ph. D. on CS. I have no idea about the legal status of 2.11BSD or, to be more precise, about the status of diction(1) and style(1).

2.11BSD license question: porting software to NetBSD

by Igor Sobrado

Hello. I have just finished porting diction(1) and style(1) from 2.11BSD to the NetBSD operating system. Those utilities are a part of the AT&T Documenter's Workbench (DWB), and are not available on the v7 and 32V UNIX releases. I asked to the people of the NetBSD Foundation about the possibility of adding those commands to the base system (as a part of the tarball with documentation tools) but they think that it is not possible, as a consequence of a licensing issue. I supposed that all the software provided in the 2.11BSD was under a BSD license, but it looks like 2.11BSD is a closed source release. Can someone, please, helping me on this matter? What should I do? Should I just drop this software? Cheers, Igor. -- Igor Sobrado, UK34436 - sobrado(a)acm.org
