I'm an 18 year old Computer Science freshman at Worcester Polytechnic
Institute.  I first heared about Linux when 0.10 came out on one of
the unix newsgroups, but didn't have a computer, so I had to wait
until I came to school here and influence my roomate into installing
it on his 486dx/33 VLB system when 0.99pl12 was around.

Since then, I installed it on two friends' computers, who are in turn
most likely spreading it around as well...

All this from a person (me) whose most advanced computer that he owns
is a Commodore Vic 20 (or my hp48g-p, take your pick ;)...

The less I have to deal with DOS, the happier I am :)

  There was a question about how to recognize my 3c509 network card from
my Linux system and I get a great help from Ptomblin. First of all I have
to thank him but I still can't configure my system.
  It may be due to different distribution have different method to
rebuild the kernel and further, some stuffs may relate to the system
developer. I hope I will not disturb you to much. :P


He replies that:-
| -----------------------------------------------------------------------
|
| Further, I already try to use ipconfig to check whether it can detect
| my network card or not. The result is unknown interface. Is it due to
| my 3C509 network card that doesn't supported by LGX version Linux?
| In fact, my kernel is 0.99.

This is because you have not configured the kernel to recognize your network
card.  You are going to have to rebuild it.

Log in to the machine as root.  Make sure you have a boot disk handy in case
something goes wrong.
cd /usr/src/linux
make config
You'll have to answer a whole bunch of questions about what you want, and
what you don't want.  Make sure you answer 'y' to TCP/IP networking, and
3c509 support.
make depend
make
mv /vmlinuz /vmlinuz.old
mv zImage /vmlinuz
/etc/lilo/install
reboot

If you did everything right, it should recognize your ethernet card when it
boots.  If you did something wrong, it might not boot right, in which case
you'll have to boot with your boot floppy, and move the old kernel back into
place.

"Hello, this is Linus Torvalds, and I pronounce Linux as Linux"
========================End of Forwarded Letter =========================

  I already tried to use Ptomblin suggested method to rebuild the kernel,
but something got wrong. Something I don't know how to do and something
error displayed, the following is summarized what I encountered:-

1) I can't find '/vmlinuz'. I already use /vmlinux instead of it.
2) I can't find 'zImage' to rename it to /vmlinux (/vmlinuz).
3) when I do 'make' after 'make depend', the following error displayed:-

   ...
   pcsp.c: In function 'pcsp_init':
   pcsp.c:65:'SND_MAJOR' undeclared (first use this function)
   pcsp.c:65:(Each undeclared identifier is reported only once
   pcsp.c:65: for each function it appear in.)
   make[3]: *** [pcsp.o] Error 1
   Leaving directory '/usr/src/linux/kernel/ ...'
   ...                                       ^^^
                      (I omitted, if you need I can show you)
My configuration is as follows:-
-486DX with 16M RAM
-Yggdrasil LGX Fall 1993 version, Linux 0.99.13 kernel
-SCSI 1740 controller
-200MB external harddisk
-3c509 network card
-Sony CD531
-Use floppy disk to boot the system up (I don't intend to use LILO as
 my boot loader because Linux is installed in D drive of external
 harddisk and can't be boot up if my external harddisk is removed)

  Further, I tried to read /usr/src/linux/README for any advice. I found
that several advices is different to Ptomblin's suggested.
The document said:-
1) use 'make zImage' to build a compressed kernel.
2) use 'make zdisk' to make a boot disk.
3) 'linux/tools/zSystem' is a compressed kernel and 'linux/tools/system'
   is uncompressed kernel.

All of above I have tried and looked, the result is as follows:-
For 1) Just like error listed above and still can't find zImage for
       '/vmlinux' replacement.
2) Floppy disk drive haven't light up and operate, nothing was done on
   floppy.
3) Both files can't find in named directory.

What can I do know? Maybe I don't know where the kernel is built and make
the replacement to '/vmlinux'.
Further, I want to know there are any command to make the boot disk after
I build the kernel.
Thank you for your help!

Nope. There's no danger of losing your right to develop software until
they send the police to confiscate all compilers. Don't think there's
much danger of that in the near future. Nor is it likely that anybody
will stop you from giving away what you've written.

Plus, if as you said in another post, by "free" software you mean only
GPL'd software, what about the large volume of freely-available source
code that's not even encumbered? You can't be serious...

My new GUS card only works under Linux if I first boot DOS and allow

to initialize the card under Linux?   I can't find any reference to 
this in the Linux Sound Users' Guide or any of the packages it
refers to.  

After it gets initialized, the GUS card works like a hose!  I'm using
mp, xmp, gmod, and vplay to play the various formats.  I'll try recording
one of these days. :-)

        I can very highly recommend the "Newnes C++ Pocket Book". 
        Whilst it is "pocket-book" format, it is 368 pages long and meets
        both of your first two requirements.  It does not address X and
        is not available in electronic form.  The thing I like about this
        book and it's predecessor "Newnes C Pocket Book" is that they
        are NOT designed as academic texts, but are instead targeted to
        the programmer already familiar with compiler concepts and logic.
        To quote from the backcover: "Newnes C++ Pocket Book will be useful
        to programmers already having a working knowledge of C as a
        conversion aid to the C++ language and to software development
        using the object-oriented approach."

        As an aside to whoever was having trouble getting books in Europe,
        this book is published by:
                Newnes
                An imprint of Butterworth-Heinemann Ltd
                Linacre House, Jordan Hill, Oxford OX2 8DP

        The specifics are:
                Newnes C++ Pocket Book
                Sexton, Connor
                ISBN 0 7506 0635 5

        These books are a real PITA to find here in the "colonies", but 
        worth the trouble.  They publish a smashing UNIX pocket book that
        I had to special order from the UK ($$$), but it's worth it! 

        Other titles:

                Newnes C Pocket Book            ISBN 0 7506 0221 X
                Newnes UNIX Pocket Book         ISBN 0 7506 0391 7

                Newnes Computer Engineer's Pocket Book (I don't have the ISBN
                        for this one - I'm still hunting for the book!)

        These little beasties aren't cheap, but are pure information, no
        fluff or dreck.  As an added bonus, PROPER English spellings are
        used, not Americanisations.  :)

        enough to drop a kilobuck to Sun for their C compiler!)

        Ok, USENET and Internet mail are my only access to Internet at the

Slackware or Soft Landing package (or any other package deal). I regretable do
not have a CD-ROM, I don't even have a tape drive, I just have two 3.5" drives
and two 2400 baud modems. I don't want to spend weeks downloading it, via FTP
by mail,  or racking up LD charges.. hehe (I'm poor enough as it is :)

        So, if anyone can e-mail me with the address and price list of the
latest Linux distribution packages, I would be overly delighted. I'm currently
stuck with .99 pl14. hehe..

        Well, thanks in advance!

Books, that fill your needs 3 and 4 are available.  Get the
documentation from X windows.  It contains the titles:

        XLib -- C Interface
        X Toolkit Intrinsics -- C Language Interface
        Athena Widget Set -- C Language Interface

I have printed them, and learned programming X from them.  They
are quite technical, and the ordering is more that of an reference
manual, than that of an introductionary book.

Start reading with the second of them, the X Toolkit Intrinsics.
You will see, that you can leave out many of the annoying details
of the XLib interface for the beginning.

The alternative is "Tcl and the Tk Toolkit" from John K. Ousterhout
(The book is available from Addison-Wesley, or a postscript draft
of it is in the tk/tcl dist).  The tk interface to X is somewhat
more flexible, and less buggy, than the Xt/Athena Widget combo.

You can use the tk interface both from C, and the tcl macro
language.

I few months ago I had a dockingstation on loan for my laptop (Which
runs linux). The docking station had a NCR SCSI controller, which was
recognized. I was working with the laptop in our workroom in
Amsterdam, and there was a NCR 6298 RAID unit with 2 ranks of 5 Gigs
each. I used a 3450 to initialize the ranks on RAID 5 (Giving a total
of 8 Gigs available) and then hooked it up to the laptop. It
worked. My A4 notebook had 8 Gigs of diskspace!!!!!!!

On the downside. NCR raid disks use a kernel driver that enables the
system to know about the state of the RAID unit. Like when a disk is
being removed (Remember the 6298 is hotpluggable), When a disk is
brought back and it controls the rebuild-rate when a disk is brought
back. This (obviously) did't work on the laptop.
