It was only when IBM started to move to 64-bits that the Austin lab (home of POWER & AIX) and Rochester lab (home of AS/400 & OS/400) were told to build 1 64-bit processor that could be used by both. OS/400 uses an extra bit (33-bits and 65-bits) for it's weird protection scheme. It is true that the AIX kernel (on POWER & PPC) was a custom written control program (written at T.J. Watson Research Center) with UNIX semanitics layered on top. This was to take full advantage of the POWER's architecture (especially in the VM area) that would have been too much work to adapt a "standard" unix kernel to. -- TTFN - Guy

I have the bookmark for the instructions somewhere, but it boils down to needing an IDE adapter that's pretty brainless, and that either has no serial ports or can be turned off, a Seagate Medalist <2GB, a goat, and 2 plucked chickens. I seriously did have to beat the drive repeatedly with the AOS LL-format utility to get it running. After it took a BSD filesystem, it then happily accepted TLC from the VM tools. Apparently, *only* the Medalist line supports an arcane instruction or sense bit or something that the ESDI adapter used and the system firmware wants to see. And, at this point, I'm not sure that a <2GB Medalist qualifies as "easily obtainable". ;) At that point I was able to power up the RT without dimming my office lights. Three very tired E70s suck some serious amps spooling up. I'd dearly love to snarf a mouse and a Matrox graphics adapter for the thing, but it's one of my pride & joy items just as it is. Doc

Quothe Jeff Brendle, from writings of Fri, Apr 02, 2004 at 03:16:32AM -0500: There's one full-height one around here somewhere, IIRC... not very much capacity, however; didn't come with this system. It's been so long since I've tried to use this machine, that I forget exactly what's in it. Originally, it had three ESDI hard drives in it, two 70 and one 40, or vice versa, IIRC. I swapped one of the drives with a 330MB Micropolis, and that worked, but one of the drives soon bit the dust, or there was some sort of weird error message; trying to remember. Going to have to power it up and see what happens... To confuse me all the more, watch it decide not to show me the error message and boot instead. :-) Will have to try to get to that drive and see what the model number is; should have at least one spare similar drive for emergencies if it's still useable. Thanks. Time to take another look... it hadn't changed the last time I looked at it though; I was just wondering if anything had changed since the FAQ was last updated. -- Copyright (C) 2003 R. D.

That is all I (or rather, the book) is claiming. I am not implying that they ever shared code. Well, I will have to go and find the book (which could take a long time), but I am pretty sure it was a major design goal for that version (AIX 3, I think?), and as I stated, was ported to other architectures that are not very POWER. If the book is misleading - well, then I have been misled. However, it is an official IBM document. William Donzelli aw288(a)osfn.org

[quoting order fixed up -dM] Like Jay, I've worked with various different unices (for most of my career, I was a sysadmin at a university research lab), and at one point one of them was AIX. And I'm with Jay on this. Perhaps SMIT makes sysadmin simple if you don't mind drinking the IBM kool-aid - but if you're trying to manage a heterogenous pile of machines and keep them more or less similar to one another as far as you can, AIX is practically guaranteed to be an outlier. Way, way out. We called it "aches" for a reason. Or at least it was back then. I don't know what it's like now. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

It would show you the command line it was about to execute. I'm not generally a GUI user for admin stuff, but the ability to setup a complex command and then view the actual commandline statement was useful. Kelly

Been searching the 'net and talking to dealers with little success. I have two computers (chrysler call them Spark control computer) I'm trying to get info on what kind of programming for different emissions systems and two types of carbs. Especially for chrysler 2.2L 4 cylinder engine with these computer, controls or uses: Non-feedback or feedback carbs, has vaccum pot on the computer itself for the advance, switches and temp sensor, soleoids (emissions stuff and/or fuel/air mixture soleoid). Some used O2 for the feedback carb. Hall effect sensor in disributor and set spark advance for spark control). Have somebody who have access to better info on those especially emssions type (fed, calif or canadian and which carb is used? I have two computers for the caravan (Part numbers are: 5227382 for 1986, and 5227379 for 1987.) Cheers, Wizard

At the time IBM introduced a totally integrated LVM in AIX - it came under heavy criticism from the rest of the UNIX community because disk drives in AIX were entirely logical and not readily RAW capable. The fact that one could add (or in some cases delete) drives and logical partitions in a running UNIX system was critical for large commercial shops. I'm not sure either. I don't recollect SMIT being available with the first release of AIX - But it was definitely available in the early eighties. I've worked with HP-UX on 9000's - and it is relatively easy to work with - but, in my opinion, AIX's SMIT is more complete and better integrated (especially in logical volume management). AIX also had from the begining and continues to have a very sophisticated and well integrated patch management system which equals that of large enterprise level systems (mainframes). On another, but related topic, someone had commented on AIX and Open Source - Early AIX releases were a pain - but later releases (say 4.3 on) were much easier to work with. Now IBM has ported tons of freeware to AIX - downloadable as source and binary from their AIX site - and is comfortably Open Source friendly. BTW: Just so you don't think I'm biased toward AIX (I'd like to think I am "fair and balanced" ;-) Here is my picks in order of: Favorite *NIX servers --------------------------- Solaris Linux IRIX AIX HP-UX Favorite *NIX workstations --------------------------------- IRIX Linux Solaris AIX HP-UX Lyle -- Lyle Bickley Bickley Consulting West Inc. http://bickleywest.com "Black holes are where God is dividing by zero"

One thing that AIX had before hpux is the ability to dynamically increase the size of its lvols. HP can now do it (and has been able to for a couple of years), but AIX has had this feature for a long time (and I was very envious of it until hp finally added it into its unix). -Bob On Wed, 31 Mar 2004, Jay West wrote:
