Various combinations of SIMM sizes are supported as long as the total amount of RAM is even. For example, a SPARC 1 configuration with 40MB of RAM is possible, combining 4MB and 1MB SIMMs. SPARC 1/1+ machines will take up to 64MB of RAM. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com - ------------------------------ Date: Tue, 27 Jul 1999 20:19:47 -0700 (PDT) From: Rik Schneider Subject: 3chip SIMMs in a 1+?

I was given a DEC 5000/200 box a few weeks ago. As an exercise (which applications I think you can see), I am trying to install netbsd in it using a W95 box as the bootp/tftp server. The server I am using is Cabletron's bootp/tftp server. So, I configured the server, told it what is the MAC and IP numbers for the DEC box and specified where the miniroot is. Then, I went to the DEC box adnd tried to tftp boot it: >>cnfg 6 6: PMAD-AA DEC V5.3a TCF0 (enet: 08-00-2b-17-91-25) >>boot 6/tftp ?IO: 6/tftp, bootp tmout >> As it can be seen from above, I got a timeout error message. If we look at the server log file, 08/05/99 03:21:53 PM BootP Server Initialized. 08/05/99 03:21:54 PM TFTP Server initialized. 08/05/99 03:26:39 PM BootP: Processing request from: 08-00-2B-17-91-25 08/05/99 03:26:39 PM BootP: Request from: 08-00-2B-17-91-25 processed. 08/05/99 03:26:44 PM BootP: Processing request from: 08-00-2B-17-91-25 08/05/99 03:26:44 PM BootP: Request from: 08-00-2B-17-91-25 processed. 08/05/99 03:26:55 PM BootP: Processing request from: 08-00-2B-17-91-25 08/05/99 03:26:55 PM BootP: Request from: 08-00-2B-17-91-25 processed. 08/05/99 03:27:16 PM BootP: Processing request from: 08-00-2B-17-91-25 08/05/99 03:27:16 PM BootP: Request from: 08-00-2B-17-91-25 processed. 08/05/99 03:27:57 PM BootP: Processing request from: 08-00-2B-17-91-25 08/05/99 03:27:57 PM BootP: Request from: 08-00-2B-17-91-25 processed. that would make me think that both machines did talk, at least at the bootp level, but tftp never started. Would you have any idea of why that happened? I know you may not have knowledge on DEC boxes, but perhaps such behavior has been found before.

SCSI devices are and if not specified it usually is + single-ended or differential single-ended + wide or narrow narrow + normal, fast, or ultra normal First the bad news: The adapter between single-ended and differential is complex, often hard to find, and unless found surplus is likely to be costly; it requires power; and it probably won't fit inside the SS2. The cable adapter between wide and narrow is simple and probably fairly inexpensive, but it may not fit easily in the available space. The good news is that you should not need to match speeds, since the controller and drive will figure out the fastest which they both support. The SS2's built-in controller is narrow and single-ended; I don't know if it's normal or fast but either way a fast narrow drive should work as long as it isn't differential. The other thing to consider for internal drives is power/cooling: it's safest not to use a drive that consumes more power (and generates more heat) than the 424 MB drives for which the SS2 power and cooling were designed. - ------------------------------ Date: Wed, 28 Jul 1999 09:47:08 +0200 From: Jonathan Thornburg Subject: SS2 SCSI drives To: suns-at-home@tigger.net-kitchen.com In SAH v12 n20, "Gregory F.

But is it a "narrow"? > Will a "fast narrow" work? Yup on both counts. In fact, even a SCSI-1 drive will work, though those are pretty rare these days. The comp.perphs.scsi FAQ has a pretty good (abeit rather PC-oriented) description of what all the various SCSI terms mean. Briefly, SCSI (nowdays SCSI-2 is the norm) defines * width: narrow or wide; SS2 are narrow * signalling method: single-ended or differential; SS2 is single-ended * speed: slow (mostly obselete now), fast, or ultra; SS2 controller is slow, but it can handle any type of drive (it just won't use the extra speed of the fast or ultra drives) The SCSI is basically the same for all the sun4c systems (SS1, SS1+, SS2, IPC, IPX, SLC, ELC). > Also, does anyone know where to get external enclosures cheap for a > scsi drive? I've bought a couple from ads in misc.forsale.computers.workstation . Typical prices seem to be US$50 to US$150. You could also look for an old PC case, or even an old PC (and strip out the innards). -- -- Jonathan Thornburg http://www.thp.univie.ac.at/~jthorn/home.html Universitaet Wien (Vienna, Austria) / Institut fuer Theoretische Physik "The first strike in the American Colonies was in 1776 in Philadelphia, when [...] carpenters demanded a 72-hour week." -- Anatole Beck - ------------------------------ Date: Wed, 28 Jul 1999 08:05:18 -0400 From: "Gregory F.

Thanks for the info. One more question: I would assume that as the technology has gotten more advanced that the drives would require less power and cooling, thus a newer 1gb drive is probably equivalent to the older 424mb drives. Is this true? /greg -- Gregory F.

If the interfaces do not match, all you have to do is get a converter and plug the drive(s) in. For example, a configuration of SPARCStation 1 with an Ultra-SCSI drive with a "narrow" connector is possible without any conversions.

Is this true? You're correct that, in general, the newer drives tend to run cooler (use less power) than the older ones while providing increased capacity. However I don't have the specific figures for either the Sun 424 or a typical newer 1GB. - ------------------------------ Date: Wed, 28 Jul 1999 10:18:38 +0200 (MET DST) From: Francesco Messineo Subject: Suns-at-Home Digest V12 #20 To: Dwight McKay > Do those 3chip SIMMs (supposed to be true parity) work in a 1+?
