The chip uses PIO (32-bit on EISA, 16-bit otherwise). While it's not DMA, it at least looks like a pretty good PIO implementation. It should be more efficient than chips with bad DMA that require memory-to-memory copies, especially if REP INSW and REP OUTSW are used for transfers. There's a document describing how to write drivers for the National Semiconductor DP83800 at http://www.national.com/an/AN/AN-995.pdf I'd appreciate it if those who have worked on LAN drivers could take a peek at the above URL and help me to assess the difficulty of adapting the ed driver. (Additional bells and whistles could include EISA and PnP support. I have absolutely NO idea how to do these on FreeBSD, but hopefully a lot of the code could be cribbed from other drivers.) Right now, the bottleneck in ISA systems with 10 Mbps Ethernet adapters is the Ethernet itself, since the ISA bus is lots faster than 10BaseT. Using a 100BaseTX Ethernet adapter would shift the bottleneck to the bus and CPU, which can run to their maximum ability and use the pacing in TCP to keep from getting swamped. (UDP could still swamp them, of course, but only if used in an ill-behaved way.) --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message From owner-freebsd-hardware Wed Dec 30 02:27:29 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id CAA28587 for freebsd-hardware-outgoing; Wed, 30 Dec 1998 02:27:29 -0800 (PST) (envelope-from owner-freebsd-hardware@FreeBSD.ORG) Received: from bayer2.bayer-ag.de (bayer2.bayer-ag.de [194.120.191.2]) by hub.freebsd.org (8.8.8/8.8.8) with SMTP id CAA28582 for ; Wed, 30 Dec 1998 02:27:27 -0800 (PST) (envelope-from ANDREAS.KLEMM.AK@bayer-ag.de) From: ANDREAS.KLEMM.AK@bayer-ag.de Received: by bayer2.bayer-ag.de id LAA20759 (SMTP Gateway 3.0 for hardware@freebsd.org); Wed, 30 Dec 1998 11:27:08 +0100 Received: by bayer2.bayer-ag.de (Internal Mail Agent-2); Wed, 30 Dec 1998 11:27:08 +0100 Received: by bayer2.bayer-ag.de (Internal Mail Agent-1); Wed, 30 Dec 1998 11:27:08 +0100 To: " - (052)hardware(a)FreeBSD.ORG" Subject: FBSD 2.2.8: ASUS P2B-S, is AIC 7890 and Intel 82558 100/10 s Message-Id: <0006800007846172000002L022*@MHS> Date: Wed, 30 Dec 1998 11:26:53 +0100 Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Disposition: inline Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from quoted-printable to 8bit by hub.freebsd.org id CAA28583 Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi !

Note that the "S" suffix means onboard SCSI, but _not_ network interface - for both onboard, you need the P2B-LS. The only reason I ended up with the P2B-S was a temporary shortage of P2B-LS with the vendor, and they threw in Intel 100 cards at the price of the P2B-LS to compensate. Other details of the configurations are PII/400, 256MB ECC RAM (max. 512MB), Matrox G200 8MB AGP (great price/performance; I'm using Xi Graphics Accelerated-X), 2 x Cheetah 4.5GB, Toshiba 32x CD-ROM. These systems work great and are certainly fast, but you need either FreeBSD 3.x, or 2.x with CAM extensions to run the Adaptec 7890 controller. > I*%m looking for a motherboard, that is capable to drive the following > components: > > Intel Pentium II 450 MHz (single Prozessor) > Matrox Productiva G100 AGP 4 MB > or ELSA Gloria Synergy, 8 MB > 9/18 GB Seagate Barracuda or Cheetah Harddisk (Wide SCSI) > DDS3 Tape (Wide SCSI) > WIDE SCSI CD-Rom > > The mainboard should have the following interfaces / connectors: > 2 s / 1p > PS/2 connectors for mouse and keyboard > USB is not necessarily needed > > Can I choose this board with the integrated SCSI and Ethernet Controllers > or should I better go an get the P2B board and buy separate SCSI and Ethernet > PCI Cards ??? I don't know of any significant disadvantage for the on-board controllers; they are both top quality. Advantages include keeping all PCI slots (4 on the P2B) open (assuming you use AGP video), and considerably reduced price. The motherboard with on-board SCSI comes with a complete SCSI cable kit too - those LVD cables are not cheap. The on-board Ethernet has a wake-on-LAN feature. > What would be the fastest possible hardware/peripheral combination in a > Desktop / Mini Tower Chassis on one SCSI bus ? I'm not sure why you say one SCSI bus. The 7890 setup on the Asus P2B-LS includes the 3860 transceiver. There are 3 SCSI busses on the one controller: fast narrow SCSI, fast wide, and ultra-2 LVD. You can put regular wide devices on the LVD bus, but then any LVD devices on that bus run single-ended at 40 instead of 80 MB/s, and the bus behaves electrically like regular fast/wide, with a reduced length limitation. (Although with one hard drive, the reduced bus speed presumably makes little difference.) Surely, the "fastest possible" configuration would involve _multiple_ high-speed LVD SCSI drives, like the Cheetahs, which not only have 10,000 rpm spindle speed, but also have reduced diameter platters, for appreciably faster access times than competing drives. How many drives you can fit in a mini-tower/desktop is another matter. My mid-tower cases (16" tall, but wider than normal at 8 1/2") could readily fit a CD-ROM, tape drive, and 3 Cheetahs with more than adequate cooling, using extra fans. The new Cheetahs have much reduced power consumption, compared with earlier 10,000 rpm drives. The heat dissipation does increase a bit with increasing capacity. The only disadvantage I know is that they are rather noisy. Note that Seagate recommend airflow across the top and bottom (large sides) of the drive: mounting in conventional 3 1/2" bays immediately adjacent to another device like a floppy (or, even worse, a similar hard drive) is probably not a good idea. Also, what about a multi-processor board, like the P2-D series? > I need CD-ROM, 24 GB Tape (DDS3 preferred) and 9/18 GB Harddisk. If you can afford it and fit it, consider splitting the hard drive storage into 2 or more smaller drives. Depending on the application, you may want to consider CCD or Vinum to help spread load across multiple drives. > Is there a possibility to drive ??? -- Graeme Tait - Echidna To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message From owner-freebsd-hardware Wed Dec 30 08:00:36 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id IAA27947 for freebsd-hardware-outgoing; Wed, 30 Dec 1998 08:00:36 -0800 (PST) (envelope-from owner-freebsd-hardware@FreeBSD.ORG) Received: from zogbe.tasam.com (zogbe.tasam.com [198.232.144.254]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id IAA27942 for ; Wed, 30 Dec 1998 08:00:34 -0800 (PST) (envelope-from clash@tasam.com) Received: from bug (bug.tasam.com [205.252.239.241]) by zogbe.tasam.com (8.9.1/8.9.1) with SMTP id LAA27867 for ; Wed, 30 Dec 1998 11:00:13 -0500 (EST) (envelope-from clash@tasam.com) Message-ID: <010501be340d$7f0f4940$f1effccd@bug.tasam.com> From: "Joe Gleason" To: Subject: Motherboard with onboard scsi Date: Wed, 30 Dec 1998 10:59:28 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset="x-user-defined" Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.2106.4 X-MimeOLE: Produced By Microsoft MimeOLE V4.72.2106.4 Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I am looking at motherboards with on board scsi for a server I am building.

There are actually 3 SCSI connectors on the Asus P2B-S motherboards I have: one 50-pin fast SCSI, one 68-pin fast-wide, one 68-pin ultra-2 LVD. My understanding is that without this chip and using the 7890, if you mix fast-wide and ultra-2 LVD devices on the wide SCSI bus, the bus collapses to fast-wide mode, and LVD (low-voltage differential) devices are forced to switch to single-ended mode, transferring at 40MB/s. With the 3860, you have two separate busses, one for fast-wide devices at 40MB/s, one for ultra-2 LVD devices at 80MB/s (in 16-bit mode). Obviously this only matters if you intend to use ultra-2 LVD devices. The LVD bus also supports longer cable lengths, although the cabling I received with the Asus P2B-S board provides for internal LVD devices only. The cable for the fast-wide bus does provide an external wide SCSI connector. > What is the difference between 7890 and 7895? This I don't know.

The problem becomes much easier if you toss the PC in the vertical direction and drive the auto on a flat level surface at a constant speed. A few equations you might find useful are: s = 1/2at**2 + v0t + s0 (for the PC) v = at + v0 (for the car, if not at constant speed) f = ma (for the impact) The trick is to drive at a high velocity, then toss the PC up and get out of the way. The general idea is to *only* embed the PC into the car and not the installer. Of course, there is another approach. You could park the auto outside a tall building. Then take the elevator to the roof and toss the PC onto the auto. This ``top/down'' method would preferred by some programmers; but, in my opinion the installer would be too far away to fully appreciate the embedding process. > > The machine in question will be connected to a rather large stereo > system, and he says a Turtle Beach soundcard (Daytona) would work nicely. I agree, the Turtle Beach sound card would work nicely. Quality audio of the embedding process is essential. Having both quality audio and video would be even better. Would you be so kind as to put an mpeg file of the embeding process out on a web site somewhere for all of us to enjoy? There are many days when I would actually like to watch such a multimedia presentation.

Actually, I want to retract this statement about the Winbond chip generating corrupt frames at 10Mbps half-duplex. Upon further investigation, it turned out that the problem was not the Winbond cards generating bad frames: it was the Netgear FA310-TX cards on the other end DMAing bad packets in promiscuous mode. I happen to have one machine with two Winbond cards, each of which was directly wired to a machine with a Netgear FA310-TX Rev D1 card with a PNIC chip. Running tcpdump on both PNICs and observing traffic transmitted from the Winbond cards, it looked like the Winbonds were sending out crap data. It was actually the Netgear cards: when the promiscuous mode bit is turned on, and there's heavy traffic being exchanged, the PNIC chip sometimes DMAs a whole crapload of data along with the desired received frame. Since tcpdump turns on promiscuous mode by default, it was tripping the bug. This only seems to happen with revision 33 PNIC chips. The LinkSys LNE100TX has a revision 32 chip (at least, the one I have does) and doesn't exhibit this problem. I communicated with Netgear support, and they confirmed that they're aware of problems with promiscuous mode with these cards, but they didn't have a workaround. I suppose most Windoze users would be unaware of the problem since Windoze doesn't use promiscuous mode. I just committed a change to the PNIC driver that implements a software workaround for this bug; it jumps through some hoops to salvage the received frames that get mangled with the bug trips. It's sort of a kludge, bug the performance impact shouldn't be too bad since the problem only seems to happen at 10Mbps (and it never happens in full-duplex). -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message From owner-freebsd-hardware Thu Dec 31 16:55:27 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id QAA10795 for freebsd-hardware-outgoing; Thu, 31 Dec 1998 16:55:27 -0800 (PST) (envelope-from owner-freebsd-hardware@FreeBSD.ORG) Received: from allegro.lemis.com (allegro.lemis.com [192.109.197.134]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id QAA10790 for ; Thu, 31 Dec 1998 16:55:21 -0800 (PST) (envelope-from grog@freebie.lemis.com) Received: from freebie.lemis.com (freebie.lemis.com [192.109.197.137]) by allegro.lemis.com (8.9.1/8.9.0) with ESMTP id LAA15392; Fri, 1 Jan 1999 11:20:01 +1030 (CST) Received: (from grog@localhost) by freebie.lemis.com (8.9.1/8.9.0) id LAA41708; Fri, 1 Jan 1999 11:19:42 +1030 (CST) Message-ID: <19990101111942.W39598@freebie.lemis.com> Date: Fri, 1 Jan 1999 11:19:42 +1030 From: Greg Lehey To: Joe Gleason , freebsd-hardware@FreeBSD.ORG Subject: IDE hot plugging (was: IDE Antics) References: <007301be34de$f89a2bf0$f1effccd@bug.tasam.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.91.1i In-Reply-To: <007301be34de$f89a2bf0$f1effccd@bug.tasam.com>; from Joe Gleason on Thu, Dec 31, 1998 at 11:59:36AM -0500 WWW-Home-Page: http://www.lemis.com/~grog Organization: LEMIS, PO Box 460, Echunga SA 5153, Australia Phone: +61-8-8388-8286 Fax: +61-8-8388-8725 Mobile: +61-41-739-7062 Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org On Thursday, 31 December 1998 at 11:59:36 -0500, Joe Gleason wrote: > Right now I have a server with 4 ide drives.

Some drives need to be jumpered differently for `alone' and `master'. If your drives are of this kind, you lose. One way or the other, though, I'd expect them to crash. I'm sure that hot plugging is way down on the list of priorities for the IDE ``standard''.

We do exactly this many times a week (some weeks). the 'alone' vs. master/slave thing is not an issue since both drives are on the same chain. We do it to clone ide drives for products. Be sure to: Power/boot the machine with both drives in place, strapped as master & slave. mount manually after drives are installed & powered. unmount manually before drives are unpowered. Never use drives of different make/model in same slot between boots. As you said, never access either drive while they are removed/unpowered. This will lock the machine (although I have successfully recovered from this by replacing the drive and powering it up, probably dumb luck!). We've done this at least a 100 times so far without failure. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
