There are 2 IDE HDs installed, one on each controller (for performance reasons). (they are Quantum Trailblazer and Quantum Fireball if this matters). I have a newly bought Conner 1G SCSI-2. Tested in other machine (PCI UMC) under 2.1-RELEASE, same card (the system ran just from that drive, no IDE was installed). When I install it, and boot my 2.0.5-RELEASE (haven't upgraded yet, would ASAP), it recognizes all the drives. I've disklabeled and newfs'ed my new sd0 just fine. When I start to `cd / ; pax -rw -X -pe -t . /mnt/root' (just for example), in plain single-user, nothing but a shell running before, it starts, then, after some short time copying files, I got: assertion "cp == np->header.cp" failed, line 5235 assertion "cp" failed, line 5236 ERROR (80:100) (7-a3-0) (8/13) @ b5c:720071d regs: da 10 c0 13 47 8 0 1f 80 7 80 a3 80 1 3 0 command failed (9 ff) @ f089cc00 this is from my paper notes (the machine is at work, I write this from home), but I hope I haven't made any mistake in numbers.

It seems that all works fine _until_ I access both IDE and SCSI. It that the problem? I have read some guys' report in relcom newsgroup telling just the same: NCR works fine but with IDE.

(-O In my efforts to keep cost low, I have come up short on documentation. I recently purchased a NEC 1Gig drive and Adaptec 2842 SCSI controller card, but vendors at the computer didn't provide documentation. I would like to install FreeBSD 2.0 on this new disk in my 486 DX2/66Mhz VLB PC which currently has an 170MB IDE drive. My searches in the archives indicate that this is possible, but explicit explanations and/or directions as to HOW to do it were not given. Who out there can coach me through such an installation? I would like to keep a small DOS partition on the IDE disk and the majority of FreeBSD on the SCSI. Are there any Adaptec drivers I need to run FreeBSD? Where can I get them on the Internet? And, to further make it difficult, I would like to do the install via ftp and a modem. What helpful hints can you give me? Is there a prefered ISP in the Atlanta, GA area anyone would recommend?

Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-hardware@freebsd.org Precedence: bulk Hi, When I check out the various RAM distributors, I can't seem to find EDO simms that also support parity! Why is this? EDO doesn't make parity a moot point, does it? How much of a performance boost does EDO provide, anyways? I'm putting together some servers where stability is a must, but extra performance is always nice.

I'm looking at a ASUS P55SP4 motherboard, based on the SiS 5511/5512/5513 chipset. I BELEIVE that it supports parity memory (the earlier SiS chipset does - anyone know for sure?), but I know that it supports EDO. Hence my question. > Having said that, I'm not terribly enamoured of parity memory anyway; what > good does it serve? ECC memory I can understand, but parity? Nehh. Ok, do you know of any good&cheap ECC-supporting motherboards? I'm trying to avoid the cost that comes with the Compaq and HP server lines. I'm trying to build the most stable system possible for the best price. I gather that you don't think that parity memory is helpful to this goal? Systems with parity memory can't do much more than halt when a parity error occurs, right? Am I right in assuming that systems with ECC memory will correct such parity-type errors and keep chugging along? Will FreeBSD work with such motherboards? Thanks for your response!

This has pretty much been the case since 486's came out, and definately since the pentiums arrived. -- Rob From owner-freebsd-hardware Thu Dec 21 10:57:20 1995 Return-Path: owner-hardware Received: (from root@localhost) by freefall.freebsd.org (8.7.3/8.7.3) id KAA26667 for hardware-outgoing; Thu, 21 Dec 1995 10:57:20 -0800 (PST) Received: from server.id.net (root@server.id.net [199.125.1.10]) by freefall.freebsd.org (8.7.3/8.7.3) with ESMTP id KAA26655 for ; Thu, 21 Dec 1995 10:57:15 -0800 (PST) Received: (from rls@localhost) by server.id.net (8.7.1/8.7.1) id NAA22241; Thu, 21 Dec 1995 13:58:53 -0500 (EST) From: Robert Shady Message-Id: <199512211858.NAA22241@server.id.net> Subject: Re: Plug-n-play boards and FreeBSD?

If so, what do I need to do? Make sure you have a plug-n-play BIOS, with a plug-n-play modem, then plug it in and play... ;) -- Rob
