An idea to the Linux Project. Make a complete new Help System/manuals :-)

Thu, 26 Sep 2002 14:18:11 +0200
Niels Larsen (njlarsen from tiscali.se)
As I initially planned to go after this with the Editors' Scissors I couldn't decide quite what to snip without having to put my own nickel's worth in at multiple places. Leaving it intact is a better example of the sort of ordinary soul who wants a simple set of instructions.
I'll suffice to say that I favor his attitude, but fear the sort of people who already have even heard of Linux Gazette might be above his "level 1" threshold, and he is not in the least bit clear where to draw dividers for his other 4 levels. He also shows a bit of intelligence and may be beyond "level 1" himself, too.
Many commercial distros come with "quick start" guides geared for the discs in the package. If you need that, I urge you, it's worth spending the money.
Beyond a fairly minimum start, what's a spreadsheet if you won't put numbers in it, an email program if you can't decide who to send mail to ... do we know any mail programs that will tell you why not to spam before letting you use them? There is more to life than simply being told, step by step, which button to push.
On the other hand, the big name distros at this point have so many applications in them that a "level 1" manual covering each would get so huge no level 1 personality would dare crack it, or the set of them, open. We used to have it as a cartoon on the wall back when I was in tech support: "I can tell I'm getting to this guy. I heard him open the shrink wrap on the manual."
But we will cheerfully point a News Byte entry at resources that make some effort to divide up the world of Linux info along the lines of how much experience you have. And yes, Mr. Larsen, that will require us to point you at a website somewhere. The weapon, should it come to exist, is no good if we truly keep it a secret. -- Heather

This mail is about making an even better manual -and help system, which ordinary endusers can understand, and read and USE. smile - positive - friendly - but not clever :-)

I am sorry, that I try to pass my idea around to various people by e-mail, but I have not yet found out the perfect way to do do.

I hope, that my ideas would saw an even better idea, because I am not that clever.

I am running my private "war" laugh to make Linux user friendly.

And this is my contribution to the Linux Project, I mean this idea.

If you don't like me, just scrap this letter :-)

There is sitting so many ordinary people out there, surfing the internet, using windows, and having lots of problems. So it is for me. I have worked with win3.11, 95 and now win 98. The screen freeze, programs cannot work together and so on. You probably know?

Therefore I now find that "D-day" has come, to attack. joking

It is time to make the millions og people, surfing the Internet, shift from windows to Linux.

But in order to accomplish this, it is needed with a campagn called: "Now Linux has become really userfriendly to install, use and surf the internet with", or maybe a better name ? :-)

Therefore my idea goes towards making e.g. 5 levels of help manuals. The total easy manual could be level 1. The levels for the professionals 2 - 5 hi

Keep -and continue developing Linux and its help -and manualsystem as is.

This level 1 manual should be made, by letting a completely newbie sit next to an Linux expert. Then they together shall install -and use Linux, and the necessary programs. Then let's say, a journalist shall write alle the stupid questions down into a manual. Just like the conversation goes on. It must be completely simple, only ordinary words.

E.g. "You take the Linux cd called binary 1, and put it into the cd box" and so on !! :-) The whole way, like this.

Then the same thing with all the important everyday programs. I mention: Start and log into Linux Connection to the internet - set up same -browser - mail program - news program - text editor - spread sheet - zip program - backup program - pgp program - wine - direct cable - real player - scandisk - webcopier (wget) - how to install a new program - and to remove it - and probably some more. Those are my minimum windows programs. I just mention those I use. I mean just the minimum number of programs. All above programs shall have this minimum level 1 manual, so people can start using Linux and more important open the individual program and immediately start using it. Only the minimum points, so you do not have to read pages and pages, to make it work. And please lots and LOTS OF EXAMPLET. That is the simplest way.

Keep all the existing (man - info - howto etc) as is. They belong to level 2 - 5 !! :-) They shall be used as cross reference. But here also is needed a complete Linux reference book, covering about everyting, because Linux now is so extensive.

I know, because I was at one point working with the High Pack surveying program. It came with huge manuals. Nobody was able to read it, og had the time. Then I made a manual of some a4 pages. I just wrote down just what I did, which buttons I pressed.

If you do not change attitude towards the paedagogic principles, concerning using computer programs, one do not move much towards getting people using Linux.

Only the minimum programs and their level 1 manuals, so people can begin using Linux. Then they later can fiddle into the more extensive matters, if they want to, or are able to.

Also, tell the programmers, to make their user programs simpler, and not having so many possibilities. Because it confuses normally people.

I say, make it SIMPLE and "talking" normally language, Do not call things devices, but floppy, cd, etc. because people do not understand it, and they then just stick to windows, because they have been brainwashed to use this!

Hope you get my message??? :-) :) :) :) :) :)

I repeat, keep the existing as is, but make this simple manual, as the secret weapon of Linux. I shall here in the end just mention, that I gave above idea to Bill Gates. But he just told me to approach him with a lawyer. He was afraid to be sued by me. But that is not my idea. Just giving a suggestion.

Maybe you can get just a tiny new thinking from this letter.

I am an old pensioner, and I can only give this idea, as my contribution to the Linux Project, which I find fantastic. But I still have difficulties in getting my Linux work. I cannot remember all I read. And please also free us from this phrase: "just go to this and this website". It is ok on level 2 - 5.

I am wondering, that now data programs has existed for so long, but still one is using this ridiculous complex manuals. I think programmers has been brainwashed by windows manuals/help system, which really is no good.

I think that the closest way to get enduser using Linux in buried in the help system, which has been neclected, I think ! I think this clever programmers are buried in the very programming, and are missing the link to the end-user

An example of what I mean: Word Perfect is a program, which main purpose is to be used to write a letter: In order to use the program do the following: 1. To open the program do so and so.... 2. To write a letter do so and so.... 3. When you have written the letter you should save it to both a harddisk and a floppy disk. Do so and so.... 4. To print the letter do so and so...... 5. And so on...... All the smart gadgets with the program is not necessary to show.

I mean, that the important thing is, to be able to use the various programs immediately.

Then if you want to do the more complex things with the program, use level 2, 3, 4 or 5. smile a lot ( I think, that even my older sister would be able to understand!)

If you can get lots of people going surfing the Internet and writing letters, as a minimum, using Linux, maybe a part of them slowly will begin digging into other parts of Linux. And that would be good, at least I think so! :-) Maybe, even that was your ultimate goal?

Sorry, if I repeat something, but I am old. Kind regards A grass root, who hope to saw just a tiny seed still -laughing - positive - friendly
September 2002.

Please do not reply, thank you :-)


PC-MOS

Mon, 16 Sep 2002 12:36:20 -0700
Derek Isbell (derek from holladays.com)

This is a multi-part message in MIME format.

[argh. stop that, it's a serious waste of bits. For a oneliner question you just sent 3 extra email header lines, and a stack of HTML.]

Where can i find myself a copy of PC-MOS?

We don't know. The fact that the Answer Guy, Jim Dennis, took a best shot at poking around the internet a number of years ago, to answer a question about it, is the best we've got. PC-MOS itself appears to have disappeared and all that remains may well be all the search engine entries that point to our dusty little tidbits on the topic.

But if you've got a Linux question, or you got a thing you were trying to do with PC-MOS and wonder if some flavor or other of Linux is up to doing that for you... please, feel free to ask in more detail!


Minimal Linux (Redhat 7.2) Installation

Tue, 24 Sep 2002 10:28:23 -0700 (PDT)
V Sreejith (sree707 from yahoo.com)

I have a 40 GB hard disk. I have Redhat 7.2 installed with all the features on the hard disk taking about 2GB. I used the grub boot loader.

Now I have done a minimal redhat(7.2) installation on my hard disk.I could not go below 275 mb though. I edited my old grub.conf that is with the first installation and added this new redhat minimum installation paths.

During the boot when i select minimum version i got an error saying bios wasn't able to reach my new installation because of the cylinder limit. So I made a work around by specifying the boot of the old installation( both of them are same versions) and changed the root to my new installation. This worked and i was able to boot into my new installation.

Now after booting into my new minimum installation i deleted all the docs and man pages and further reduced my installation size from 250 mb to about 135 mb. After this i used the dd command to image the new installation to another linux partition which i created and having a size of only 200mb. I copied only the first 135 mb from the source partition to the target partition.

I added another label in grub.conf to point to this partition and tried to boot. But after some initialisation messages it stopped after showing the message kernel panic. I saw a message stating that "attempt to access block beyond reach" and showed the block limit on the partition and the block which was tried to access. Obviously the block it was trying to access was beyond the limit.

I am doubting whether this is some kind of fragmentation problems.Whether the first 135 mb of the source disk doesn't contain all the installed data. Could it be that this data is scattered all over this partition and i cannot image it directly into another partition. If that is the case what can i do about this? Is there any defragmentation tools available under linux?

My aim is to reduce the linux installation size and to make an image of this reduced installation on a seperate 200 mb disk and to be able to boot and work on it.

I actually don't know whether this method works.This is a sort of experimentation.

Are there any other way of achieving this aim?

thanx

K.Woodward (kwoodwar from mindspring.com)

Hi,

I have a problem trying to setup Linux to access the servers at the University of Phoenix. The servers (Microsoft IIS) require a "log on using Secure Password Authentication" under Microsoft Outlook Express. I understand that this requires a email and news reader to authenticate using the WindowsNT Challenge/Response (NTCR) protocol [a really bad use of the http protocol]. The school does have a website to get to the email and news groups but it is timed and is very particular and seems to like rejecting Netscape Navigator access. The UOP Tech group's pat answer is that they only support Outlook Express under Windows, I want a Linux answer.

Is there any program or daemon that I could run to allow me to authenticate using this protocol so I could use Linux based email and news readers? I have tried using pine, staroffice, and leafnode and several others which are common under KDE/RedHat 6.2.

Thanks,

K. Woodward

I am using linux to try to connect to UOP now and have not found an answer to the problem that you had did you ever find a solution that worked if you did could you outline it for me.

Thank you,
Pat Norton

[LG 82] 2c Tips #2 completion

Wed, 04 Sep 2002 16:58:19 +0700
Bill Thompson (billt from samart.co.th)

Adam,

The site for this Tip doesn't appear to be up any more. Do you have an alternate source or can send me the rpm or the source rpm?

Thanks,

Bill Thompson

I (the LG editor) was unable to reach that link when I was proofreading 2-Cent Tips ("connection timed out"), but I was hoping it was a temporary error. We at LG do not have any alternate sources or RPMs. Maybe Adam who submitted the tip does. -- Mike

I usually go poking around for them on rpmfind.net if I know some file they contain, or on freshmeat.net if I know the name of the project, in the hopes of finding whatever upstream source tree might remain. Sometimes I can find out why there's not an rpm anymore, but that's pretty rare. -- Heather

Grabuñ £ukasz (l.grabun from arr.gov.pl)

First of all: LG is great! One of the best newsletters (?) I've ever read. Easy to browse webpage, understandable language, various topics. Great, just great.

There's just one thing I'm missing: there was a column for Emacs - fans, a nmber of articles about vim, even nano was mentioned. And what about jed? It's as powerful and customizable as emacs, but much lighter and easier to use. Will there be a few lines about this great tool?

regards,
Lukasz Grabun

We'd be happy to publish an article on jed if somebody volunteers to write it. Would you? The Author Information at http://www.linuxgazette.com/faq/author.html shows the desired HTML format.


Penguins, Lizards, and Pandas?

Mon, 23 Sep 2002 10:38:12 -0400 (EDT)
Virtual Sky Media Group (virtualsky_sk from yahoo.ca)

I'm proud to say that I've been a Linux user since July 2002 and I've enjoyed my new found computing freedom very much. I've also learned a lot, too.

I began my Linux experience with my purchase of Mandrake 8.2, a great distro. for a beginner, like myself. I also started out using KDE as my desktop manager, but have now found new liberties with the use of Window Maker. Which brings me to my submission to you today.

Linux itself has the wonderful Tux as its representative. KDE has a dragon-like lizard, and Gnome has a footprint of a gnome, I'm assuming. After reading from the Window Maker web site, I learned that Window Maker has chosen a Panda as it's mascot. So, I decided to make a contribution to the line up of cute and cuddly cartoon PR "toons" with this drawing of Amanda, the Window Maker panda:
[cute Windowmaker panda]

Oh, that's soooo cute! A panda with an attitude. /me likes. :) -- Ben

Now, don't you just want to start using Window Maker? :o)

Nope. :) But then, I'm an "icewm" junkie from way back.

I think I'll have to lobby Marko Macek for a mascot now. -- Ben

Keep the very informative issues of Linux Gazette coming! I enjoy them very much.

David Bouley

Glad you like'em, David! Stick around; there's always more good stuff in the works. -- Ben

An explanation sidebar might be inline about what a PNG is, why GIF, and now JPEG, are Bad Ideas, and why Internet Exploiter 5 doesn't know how to deal with PNG's. At least not as URLs; maybe it gets them right as inlines... -- jra

The only problem I've seen with PNG is that Netscape 4 displays a solid filled rectangle instead of the image if the image contains any transparency.

As for JPG, I've heard conflicting information on whether any patent applies to it, but the last I heard was that there wasn't a problem. Have you heard differently? -- Nike

JPEG is fine. The so-called JPEG patent is bogus, and if Forgent tries to use it, they will lose it (like BT and the hyperlink patent) (This is from the leading defender of software patents, Greg Aharonian: http://www.aful.org/wws/arc/patents/2002-07/msg00029.html)

PNG support in browsers (inluding MSIE) is "quite good":
http://www.libpng.org/pub/png/pngstatus.html#browsers

(Linux Journal has been using PNG instead of GIF since our redesign last year, and there have been no complaints.) -- Don

And of course, Don ought to know, since he cheerfully burns all GIFs. (http://www.burnallgifs.org) It's a good site to check on why a number of patents out there are really quite foolish. -- Heather

In any case, PNG and JPG have quite different uses. PNG is good at compressing line art but bad at compressing things with lots of colors (e.g., photographs), whereas for JPG it's the reverse. Whenever somebody sends a GIF to LG, I convert it to both PNG and JPG, and take whichever one has the best compromise of small size and color brilliance. It's not always one or always the other. Sometimes the sizes are hugely different, as in one being four times the size of the other. -- Mike


Thank you!

work, the real address of the Linux Gazette Answer Gang is:

Mike Orr (Linux Gazette Editor)

Please do not publish my email address; I will read the Gazette for any responses.

Email address will not be published. It shows up in this correspondence, but there's no public archive of this list.

We do publish addresses for Mailbag items and 2-Cent Tips, but not for Answer Gang questions. That's Heather's choice as the TAG Editor Gal. If I were doing it I'd publish addresses in the Answer Gang column too, because why should that column be different? In any case, you don't know which of the three columns your letter might appear in. A lot of it has to do with whether it produces one or two short replies or a long discussion.

So the only way a reader can guarantee his/her address won't be published is to specifically ask us not to.

-- Mike

Originally, the Answer Guy column was purely the answers of Jim, but as it changed, The Answer Gang column is now about matters which have pretty much been solved, or discussed to death in some fascinating way. Therefore unless the original querent's problem remains unsolved -- a real stumper -- there's little need to provide his or her email address, but we do mention the name.
In the case of Tips other people may have useful comments, so the address is offered.
Unless, of course, they'd like to be anonymous.
People do not get selected for Help Wanted if they wish to be anonymous. You can't beg a few thousand readers for help that way. They just have to have a complete and interesting enough description to tantalize one of the Gang to answer them. -- Heather

[ An 8 line sig block claiming confidentiality, erased per its instructions. ]

Must be confidential indeed; it didn't say anything but this!

This mailing list (The Linux Gazette Answer Gang, which makes its home at linux-questions-only@ssc.com) is not a confidential location. It is a mailing list filled with a medium sized handful of Linux folk, who expect as their main pay a bunch of warm fuzzies and the knowledge that a really juicy answer can be published for the readers of our monthly magazine. Opinions are likely to run rampant, conclusions may or may not occur (we guarantee nothing) and attachments in HTML are often ignored or grumbled about unless you're defending a foreign character set (yes, we have translators). It's a good idea to actually dust off your sense of humor because we definitely use ours.

If you need an answer in some business-like fashion, you'll have to consider a consultant instead. LinuxPorts has a good list of them.

If you want an answer in a "Making Linux a Little More Fun" fashion you'll at least need to provide us a real question, and if this sig block of yours is automatic, a disclaimer that supercedes it and grants publishing permission. We have examples in our "Ask The Gang" FAQ; see http://www.linuxgazette.com for more. Lots more :)

Your HTML attachment has been sent to the shredder; it wanted a snack and we won't be passing out candy for almost a month !

Letter of inquiry

Thu, 19 Sep 2002 02:16:09 -0700 (PDT)
dang mangaoang (jomegs143 from yahoo.com)

Dear Sir,

I am writing this letter to inquire about your product Red Hat Linux. I saw Red Hat Software's advertisement . . .

Red Hat is a company of its own; you should follow contact information provided in the advertisement. -- Heather

Try
http://www.redhat.com -- Dan Wilder

We don't make Linux, we just blather about it.

See
http://www.redhat.com as well as
http://www.linux.org and probably
http://www.li.org not to mention
http://www.tldp.org

-- jra

. . . for version 5.1 of Linux in the issue of Linux Journal.

That's an interesting case of time travel you have there; you've reached the Linux Gazette, which is a related pubication in that we're hosted by the same publishing company.
Red Hat 5.1 is quite ancient... -- Heather

RedHat is up to 7.3 in production release, and there's a beta 7.4 out there somewhere, I think, rotting people's cats' teeth. -- jra

They [Red Hat] are mirrored in a number of countries so it should be possible to find an instance of the 7.2 "GPL edition" disc on servers nearer to you. Beware that downloading 650 MB can take a while, though. -- Heather

I was quite impressed with the capabilities as listed in the advertisement, and I would like to learn some more about the product. I am a student and we are studying about Linux and this is the reason why I want to learn more about the product.

Running older versions of Linux for experimental purposes, or studying what was claimed of Linux a few years ago to see how it has grown, are both valid student projects. -- Heather

another thing is I want to subscribe a magazine about linux operating system.

In that case you came to the right place, almost :D
I cheerfully direct you to the website for Linux Journal, http://www.linuxjournal.com where you can use a secure connection to subscribe, or find more information about having it sent to you monthly.
Linux Gazette is only available as a webzine although that leads to some unusual "subscription" models in the form of Sitescooper, debian packages (lg-subscription), and services that can tell you when a website changes. These features are not provided by staff of the Gazette but rather, by volunteers elsewhere. -- Heather

Hope you could reply me as soon as possible.

Sincerely yours,

Dang

Hope you found this useful!
Thank you, and enjoy Linux. -- Heather

John R. Sowden (jsowden from americansentry.net)

I subscribe to various linux/dos/security/pascal/xbase lists, so knowing what "ssc" is is somewhat difficult. Once a month you send me a reminder to make sure I still want to subscribe. Please consider describing the various subscriptions, including other ones that might be of interest.

SSC is Specialized Systems Consultants, Inc, the company that publishes Linux Gazette, the print magazine Linux Journal (http://www.linuxjournal.com), and books and reference cards about Linux/Unix. The message you get once a month is from our mailing-list server, reminding you how to unsubscribe or change your settings. Other mailing lists we run are are at http://www.ssc.com/mailman/listinfo and in the top right corner of http://www.linuxjournal.com . A few are discussion lists, but most are announcement-only lists (newsletters).

How to Ask a Question

Fri, 30 Aug 2002 09:48:01 -0400 (EDT)
Naresh (nganta from myrealbox.com)

How can I ask a question to the answer gang?

Naresh

Send your note to the address: linux-questions-only@ssc.com
Make your subject a useful one.
Make your description of what you're trying to do, and what is going wrong, sufficiently detailed and interesting that some of the gang can answer it.
We might answer in a big burst, or after a long time, or not at all. A small portion of the "not at all" get pubbed as Help Wanted and readers from all over the world may give those a shot - but for that the description does have to be pretty clear.
We've more details in the Linux Gazette FAQs.
Good luck! -- Heather

Regarding Bessie's problem in the sept. 2002 issue of LG (Help Wanted #1): http://www.linuxgazette.com/issue82/lg_mail.html#wanted/1

I also have one of these printers, and it has worked nicely, at least for monochrome. I have done limited color testing - early on, it would print in color if I selected a different printer driver at that time (bj 200 is only capable of doing monochrome). Colors were somewhat washed out, and i never got around to really testing things like gamma correction. Besides, that was some time ago, before cups et al.

I sent bessie an email asking if she were using cups. There is a little difference in the revs of cups at least with Mandrake 8.1 which is what I'm currently running. If I use printerdrake, i am able to select a bj200 driver, which is perfect for doing monochrome printing, and the test page prints just fine. If i use another printer configuration tool, there is no corresponding entry for my printer. However, selecting a similar model driver is doable if the exact model is not listed -- and seemingly in (how?) recent cups it is not. And seemingly, there are different printer databases. (i built cups 1.1.10 I think sometime ago from source).


sendmail and Courier

Dan Wilder (dan from ssc.com)
This is in regards to September's help wanted #2: http://www.linuxgazette.com/issue82/lg_mail.html#wanted/2 -- Heather

Hi,

First, you'll have a problem using sendmail and maildir, since, sendmail does not support maildir, only qmail and postfix support this. If you've a

However, consider using procmail as the local delivery agent. I believe sendmail will support this, though I should mention I haven't used sendmail for quite a few years. Anyway, procmail supports maildir delivery.

-- Dan Wilder

A different reader seemed to believe that sendmail cannot, only postfix and qmail -- but yet another reader chimed in that it's the default on his distro for sendmail to use procmail as its local delivery, after which it's of course no problem. Sadly they had confidentiality notes on their mails, so no juicy details. Sorry. -- Heather

This is for help wanted #3 in September's issue: http://www.linuxgazette.com/issue82/lg_mail.html#wanted/3 -- Heather

Determine if the mail server is trying to perform reverse resolution for your IP address. This can lead to odd time-out problems with various services. A quick test is to add a mapping for your IP address to the mail server's /etc/hosts and see if the problem goes away.

Maybe i'm wrong ... but it can be ...

Regards :)

Babs here has to at least be partly right. Postfix doesn't speak POP3 -- it speaks SMTP! Common pop3 servers include qpopper, solidpop, or ipop3d. -- Heather

Hello Matt and LG,

My name is David Ranch and I am the author of the IP Masquerade HOWTO as well as the TrinityOS documentation project.

Anyway, regarding your eth0/eth1 issue, have you checked the DUPLEX setting on the Ethernet switch? The tell-tale signature of this is the "carrier" transitions in your "ifconfig' output. Since you have a switch and not a dual-speed hub, make sure it's set to FULL DUPLEX for that port connected to eth1. You also might want to force the speed on that port to 100 as well. Ethernet auto-negotiation has always been a problem.

If that doesn't fix things, do you have a different Ethernet card to try? Personally, I think all LNX* network cards are pretty crappy though they do work. I've had great luck with any Tulip-based network card (Netgear FA310 [not the 311, etc]), Intel EtherExpress, etc.

Ps. The comment from Heather at the bottom of

http://www.linuxgazette.com/issue82/lg_mail.html#wanted/4

is plain wrong. The IPMASQ code has supported ICMP MASQ since the Linus kernel 1.2 days (possibly earlier).

--David

In fact, I did see some references to it behaving correctly - later - but never have figured out why it wouldn't work in real life while I was dealing with it. Which means that while it's surely supported, if I'm in a situation on a 2.2.x kernel where ICMP is not working past NAT, I have no idea how to convince it to start working.
Oh well, we all have our specialties; I'll go back to tweaking X displays and tuning up laptops, now.
I absolutely agree that the Tulip chipset is the good stuff. Never leave home without it. -- Heather

Hello John, LG,

My name is David Ranch and I am the author of the IP Masqeurade HOWTO as well as the TrinityOS guide.

Anyway, I saw your LG question:

http://www.linuxgazette.com/issue82/lg_mail.html#wanted/5

First off, one of the posters mention that EQL is the solution. This is incorrect as EQL is rarely supported any other terminal servers than possibly older Livingston Portmaster. Like you mentioned, you want MultiLink PPP.

Oops, I thought they were one and the same. Thanks for pointing out my misconception. -- John Karns -- Heather

Before you start looking into setting this up, you should call your ISP and see if they allow ML-PPP? Many don't and the few that do usually only support it for ISDN users.

Good point, one which I forgot to make. -- John -- Heather

Anyway, here are some URLs that should help you in your MLPPP quest if your ISP does infact support ML-PPP for dialup users.

And thanks for the URL's. -- John -- Heather


power management

Hello.

My new PC running Linux has the new Intel motherboard that supports only ACPI, not APM. I understand from the vendor that Linux does not support ACPI as yet. Hence, I can't put my machine in stand-by or sleep mode. The only solutions are to keep it running (room temperature gets high during day time ~80 degrees) or power off.

Is Linux planning to support ACPI any time soon? Are there other alternatives to power off? After all, one of the best advantages of Linux is that you don't need to boot it every time you want to use the machine. It can run for a long time without crashing.

Thanks.
SG

[Ashwin N] Linux has support for ACPI in 2.4.x kernels. I suppose it wasn't there in the older kernels.
You'll need to install/upgrade your Linux distribution/kernel.

Hello. Thanks for the prompt reply. I guess the vendor knows less about Linux than I do. He installed RH 7.3 with kernel 2.4.18-3 on the PC, which as you say supports ACPI. Unfortunately, it is not activated. In the directory /etc/rc.d/init.d I can find apmd but not acpid. Do I have to reconfigure/recompile the kernel to get it working. I checked up all the Linux How-Tos and FAQs and can't find any information about getting ACPI to work.

Thanks.
SG

[Rick Moen] Googling found this unofficial HOWTO: http://www.columbia.edu/~ariel/acpi/acpi_howto.txt
It's linked from this summary page:

And perhaps you've already come across the ACPI 4 Linux Project:

Adding Win98 to a second HD

Nigel Ridley (nigel from i-amfaithweb.net)

O.K. I know this is a lame one but I don't want to mess up!

My children are now of the age that they are fighting over whose turn it is on the (old) computer - it has Windows 95 and (unfortunately) they like some of the silly games that children love - namely Mario (no I haven't found one to run under Linux).

So now I am under pressure to use my Linux box as a second Windows machine to satisfy the children (no funds for even a second hand 'puter).

On my Linux box I have two hd's, one 20 GB - the main one and a second one of 6 GB. I want to put Windows 98 on the second hd. How do I make sure that Windows uses the second hd and not wipe out my Linux one? Also how do I rescue the mbr from Windows after the install? - I'm using Mandrake 8.2 with Lilo.

Nigel Ridley

[JimD] Take out the Linux drive. Make it a slave. Install the smaller drive (as standalone at first). Install Win '9x. Change the smaller drive to be the master (if necessary) and re-install the big drive. (Leave a small non-DOS partition near the front of it if you can).
Now boot from a rescue CD or floppy specifying root=/dev/hdbX (as appropriate) and add the appropriate entries for an "other" stanza to your /etc/lilo.conf. Then run /sbin/lilo to install a new MBR on the little drive.
(The MBR on the big drive will be preserved, irrelevant until it's put back into a system as a master or standalone).
You might not need to use that small non-DOS partition that you created --- but I'd reserve it anyway (if the Win '9x installer will let you). You can boot from a Linux rescue disc or diskette to run Linux fdisk and mark the small partition as OS/2 or with some sort of hibernation volume type --- anything but Linux, since I hear that newer Microsoft releases with eradicate Linux partitions with extreme prejudice :) .
There are undoubtedly a multitude of alternative approaches. You could use GRUB and it's notion of "hidden" drives (to swap the identities of the two drives during the boot process, in memory). You might be able to install it (standalone) and then make it the slave (LILO) but I think MS Windows would get unhappy about not having a C drive.
[John K.] If one is resigned to using sharing the system with the rogue OS, then the above is another good reason to keep MSW straight-jacketed in an environment such as a virtual machine where it can't do any damage to things it has no business touching.
[JimD] I think John is thrying to suggest that you could use VMWare (or Plex86 if you're daring, or WINE) to run Win '9x as a process under Linux.
This works pretty well --- but has a few downsides that might apply to you're needs:
  1. VMWare needs lots of memory and plenty of CPU horsepower.
