How do VMS Condists work?

by Antonio.Carlini＠riverstonenet.com

>OTOH, what forces you to upgrade? - If you want to cluster a VAX to an >Alpha running 6.1, that should be OK: this is the usual way to upgrade a V6.0 on VAX was OK but short-lived; V6.1 was somewhat better. Most people either stayed with V5.5-2 or moved rapidly to V6.1 or V6.2. I believe that the VAX V6.1 CDs were the first ones that could be booted directly into OpenVMS (rather than just being able to boot S/A BACKUP to restore the .B saveset). The Hobbyist people should be able to supply V7.3. If they cannot do so, then I believe that you are allowed to acquire media by any means (specifically you can have someone copy the CD for you).

Kevin, cctech is a pointless mailing list. It was supposed to stop off-topic postings but the concept wasn't thought out very well. Hence, no traffic. Everything is going on at cctalk.

How do VMS Condists work?

by Antonio.Carlini＠riverstonenet.com

>I just tried, my VAX 7.2 VMS CD also boots into a minimal VMS from SYS1 >on my MicroVAX. So I guess they changed it between 7.1 and 7.2. I don't know where they changed but I looked at a V7.1 binary disk and it had a [SYS1] directory with many files underneath. The easy-to-spot difference between S/A BACKUP and full OpenVMS boot is the number of files. I don't have either V6.2 or V6.1 to hand so I don't know if this (undocumented and unsupported) facility was there back then. If you tried booting V7.1 and it didn't work, then either I looked at something other than V7.1 or you booted incorrectly. Antonio

0T- Old linux question-Redhat 5-networking

by rhudson＠cnonline.net

Hi, This is a question about an older linux.. I am running redhat 5, on an IBM755c (486) OH perhaps my laptop is old enough... : ^ ) Anyway I have to enter the following lines every time I reboot: modprobe ne io=0x300 dhcpcd ifconfig eth0 up so networking is ready... my question, Anybody know the --proper-- place to put these 3 lines? I could just put them in local.rc and be done wid um, but that wouldn't be the --proper-- place to put them. Thanks! : ^ )

I read Jay's proposal (which he posted to classiccmp). I even replied (privately) with a suggestion about how to do one of the things he wanted to do. What I didn't do was think about the proposal and realize how this was likely to play out. Hindsight being 20/20, I now recognize my error. So. Can we just blame me and quit kvetching about this 'til the next time our most gracious list host feels like it's time to make a change? -Frank McConnell

VAXBI trouble -- I just killed a bunch of boards -- haunted VAX in my basement

by Antonio.Carlini＠riverstonenet.com

>Normally, a machine that damages boards has got PSU problems (the 5V rail >sitting at 12V or something). Do you know what the outputs of the PSU >should be and can you check them? (use a 'scope as well if you have one >to look for HV ripple on the output -- a common failure mode of SMPSUs is >a high ESR (or open) output capacitor and you can then get 10-20V spikes >on the 5V output...). I no longer have one to look at, but from memory, the 6K regulators are at the back and the outputs are shielded by transparent plastic covers. Should be easy enough to remove these and 'scope away. Note however, that these are there for protection: the voltage is low but the current is high - remove metal from body before trying this out! >One board damaging another is less common unless some component failure >is shorting one of the pins to a supply line or ground. It can happen (as >here). Do you know what to expect on each pin (I guess not, as AFAIK DEC >never published real technical documentation for the VAX 6000 series). The 6000 tech manuals tended to concentrate on the programming aspects. There was an XMI handbook which covered the bus signals and protocol in some detail. >If there are any recognisable chips on the boards (especially bus >buffers), check them. And if there are picofuses for the supply lines >(some machines have them, I have no idea if the VAX 6000 is one of them), >check those too. It's not unheard-of for a bus short to blow a fuse and >not damage much else. The XMI connection was handled by a dedicated chip (in the "XMI corner") with possibly a few drivers and such strung around it (much the same concept as with the VAXBI bus). I would be surprised if a dead XBIA managed to also take out an associated XBIB. There are rules about which boards can go in which slots etc. I had a few "funny turns" with my 6K but it always turned out to be a badly seated board, or a missing cable or the problem being somewhere else and me being in a rush. My first step would be to ignore the VAXBI, remove as many boards as are needed to get the thing to start at all (which in this case seems to mean remove the BI-XMI interface boards) and then add in the XMI end of the interface. Now try to run diags and see whether the board is even partially alive. (Obviously it will fail the tests that go look for the other end of the interface). If OK so far, empty the VAXBI cage and add in the BI end of the interface board, properly hooked up. Pay careful attention to the transition headers and plugs on the BI and XMI interfaces. Now see if the diags are happy or not. If OK, season with further BI boards. I did this a few times myself and always ended up with a full set of working boards. Maybe I was lucky, maybe there really were problems with boards being badly seated or maybe I had a marginal board or two. Since all my problems happened when I needed to reconfigure the hardware, I assumed it was just seating rather than marginal hardware. Antonio

Making an MMJ to DE25-F adapter

by bob_lafleur＠technologist.com

I have an adapter that has MMJ female and a DE25-F connector. The adapter needs to be "made" (i.e. I've got wires coming out of it that plug into holes in the DE25-F connector). I want to make it so that I'll use an MMJ cable from the console port of my MicroVAX 3100 to the adapter, and plug the adapter into the 9-25 adapter cable that's connected to my PC Serial port. How do I wire it? I've got these color wires (not in any particular order) Red White Blue Green Yellow Black Which holes should I plug which colors into? Please describe how I should orient the connector when describing which holes to plug the wires into. Thanks. - Bob
