Perhaps I'm missing something, but when I found that Linux didn't like my
G2K P5-66 hard drive I *immediately* got suspicious and started rooting
around in the advanced CMOS settings.  Not having a clue what many of them
were (I'm not a PeeCee hardware guy) I simply turned off anything that
looked to me like it might be a fancy option for the IDE interface.

My drive was recognized on next reboot, so I went back and after a couple
more quick reboots I knew which option had done the trick.  Later I looked
it up to see what it was and I guess it sort of makes some vague sense to
me.

You should turn off the "IDE LBA Translations" (or something like that --
my manual is under my notebook at the moment and the G2K has some active
connections on it).  LBA stands for Logical Block Assignment, I presume (or
perhaps read).  I would guess it has something to do with the >1024
cylinders and some silly BIOS limitation.

Anyway, I've been fine since.  Not really understanding all this stuff, I
decided to be cautious and put all the cylinders above 1024 (and some below
it) into my swap partition (1016 - 1048).  I get a complaint about that
partition having "different physical/logical endings" but everything
*seems* fine.  I tested things by forcing major swappage once, and the
machine seemed ok.

I guess I'm posting this because I figure I must have the same motherboard
and drive as you guys, so my experience might help.  I guess I also wanted
to get a reality check in case what I've done is completely crazy.  Like I
say, I'm *not* a PeeCee hardware guy (*Mac* hardware I can handle ;-) --
guffaws all around...).

Yes, lead by wpp@marie.physik.tu-berlin.de (Kai Petzke), who did the

And it's not a "de facto" standard.  It's a "de jure" standard.  I.e. it's a
standard because OSF (and others) have declared it a standard, not because

   I just wanted to point out that the GPL has come head-to-head with
   corporate lawyers at least once before (NeXT's Objective-C compiler)
   and the GPL won. (I don't know whether it was a sudden fit of ethics,
   or they were afraid that a competitor might pay the FSF's legal bill,
   or what...)

More precisely, the FSF "won".

Point being that if y'all are talking about someone violating the GPL,
you'd better contact the owner of the copyright of the code being
violated.  Only that person or organization decides whether to
prosecute the violation -- perhaps a license agreement other than the
GPL has already been reached between the parties, for instance.

Here are some examples.  If someone is shipping a binary derived from
GNU C (GCC) or GNU EMACS, but not offering source, contact the FSF,
since they're the copyright owner.  If someone is shipping a
derivative of Linux without offering source, contact Linus Torvalds,
who is, last I heard, the copyright holder of the Linux code itself.

In the Linux case, assuming Linus is indeed the copyright holder,
he can decide whether to investigate the alleged violation, how to
handle it, whether to sue, whether to separately license Linux (say,
to Novell) for profit (or beer), whatever.  (Such licensing would
not affect the GPLed licensing of existing versions of Linux, but
it could permit enhancements Novell made to Linux to be proprietary.)

If, for some reason, Linus (or some other holder of GPLed code)
was unwilling to deal with GPL violations the way the FSF intended,
that might be their right, but it is also the right of all of us
to pool funds and offer to buy the copyright on Linux from Linus
and donate it to the FSF or to some other organization that will
fight the good fight in Linus' stead.  Or, if Linus was unable to
litigate due to lack of funds, we could donate money directly to
him, I suppose (though many GPL supporters would probably prefer that
copyright be transferred to the FSF, which already has experience in
these matters, and might indicate their preference by not donating
to Linus but rather to the FSF once the transfer was done).

In summary: the GPL isn't really a magic bullet, it's just a regular
bullet that requires both a regular gun and a regular guy to point
it at someone and pull the trigger when needed.

Subject: 32-bit Novell desktop OS combines Unix, DOS 7
Date: 17 May 1994 19:26:52 GMT

PC Week, May 16, 1994
By Anne Knowles

Novell Inc. is targeting July for the launch of its 32-bit desktop
operating system called Corsair.
    Tentatively priced at $99, the operating system combines Novell
DOS 7 with a kernel based on Linux 1.0, a Unix clone for Intel Corp.
PCs that is freely available over the Internet, according to a Novell
internal document examined by PC Week.
    The document describes Corsair as an "enterprise networking client
fully integrated into NetWare and Unix networks."
    Code-named Expose, the software will run on systems based on Intel
and PowerPC processors and "other leading RISC platforms," according
to the document.  Users will be able to run Windows, DOS, and Intel
Application Binary Interface-complient Unix applications
simultaneously.
    A "virtual world" 3-d graphical interface will emulate real-world
job functions, thereby reducing training costs and increasing
productivity, the document states.  Corsair will also feature a
World-Wide-Web brower that may be based upon, or similar to, Mosaic, a
popular interface that is also freely available via the Internet.
    "All elements of the Corsair user interface are remotely
manageable, further reducing support and administration overhead," the
document states.  However, there were no details regarding which
network or systems-management protocols, platforms, or applications
are supported.
    A Novell spokeswoman cautioned that there is no set release date
for Corsair.  And since corporate buyers already must sift through
several commercial operating systems, some users questioned where the
new software would find a home.
    "It would be something we'd look at, but I don't really see a
compelling reason to change to it," said Mark Butler, systems
administrator at the state of Washington's Department of
Transportation, in Seattle.  "We are stabilized on Windows 3.1," said
Butler, who supports about 1,000 NetWare and Windows 3.1 users.
    "We'd have to be able to support [Corsair] without any problems,"
he added.  "We'd accept some performance degradation [on Windows
applications' performance], but we want plug and play.  If it requires
a lot of complexity, we're not interested."
    Another NetWare user had a similar reaction.
    "I'd be interested in implementing it as an option on a subset of
machines to provide an interface to the outside world," said Peter
Brantley, MIS manager with the AIDS office of the Department of Public
Health for the city and county of San Francisco.  "But I couldn't
adopt it as a desktop because of lack of funding at the department.
    "Sounds great, neato, but I couldn't see it being more than a
couple machines," Brantley added.  "Anything more than that seems
foolhardy."
    According to sources, Novell Chairman Ray Noorda picked the
Corsair name for what has been his pet project.  At one point, the
Provo, Utah, company decided not to continue developing it, but Noorda
put forth his own money to keep work going.
    Corsair will be available through all of Novell's sales channels,
according to the document.

told them to be). Do people use dvi output and some dvi translator? Thanks
in advance for any information.

Subject: Bug report (?): Gnu C++ 2.5.8 with Linux 1.0.8 (Posix) or 1.1.0
Date: 20 May 1994 12:10:41 +0200


Hello,

I think I've found a bug in either the Linux floating point emulation code
or the Gnu C++ compiler for Linux. When the running the following piece
of code I get a Floating Exception:

// BUG.cc : expose bug in floating point handling when using class
//          parameter

class some_class { public: ~some_class(); };

some_class::~some_class() { } // empty destructor

float func(some_class n) { return 1; }

int main()
{ some_class p;

  float f=func(p);
        f=func(p);
} 

// End of BUG.cc


The problem is clearly the combination of a float return argument and a
parameter of a class with an (empty) destructor. If either is removed
(i.e. the type is changed to int or void, or the parameter is given
another type) the bug disappears. The exception is raised on the second
call to the function, although I think any reference to the variable p
will raise the exception.

I've compiled this with version 2.5.8 of the GNU C++ Compiler, both on
a straight out of the box Slackware system (version 1.0.8 (Posix)) and a
slightly modified Linux system version 1.1.0. Both gave the sazxme
exception at the same place.

Unfortunately I have no expertise in either Linux, C++ or GNU compilers
to give a more accurate or precise description of the bug, but I hope
this will be enough to be able to replicate it. You can always ask for
more info when necessary.
