PM 4 or 5 will do partition moving and resizing fairly safely. Say about 99.5%
if you are a gambling sort of person. I have resized many partitions
succesfully using PM 4 from a boot disk.
And yes, when you delete remove a partition, it will not be automatically
recovered. You will need to resize the Winblows partition to recover this
unused space.
And I know the irony of dissing MS when I am using it, but Linux won't boot on
my Azza MB and I am too cheap to upgrade right now.

Well, hit www.kernel.org for the kernel. Remeber, these aren't supposed
to work perfectly and thus sometimes don't.
Yes, you'll lose any specific kernel settings. If you are referring to
modules, then make sure you build the same ones into the new kernel and
you should be fine. Double check names prior to rebooting though to make
sure there aren't mod name issues. Other than that, kernel compiling and
installing is the key to thoroughly understanding how Linux works so
good luck.

Interesting question, but really, Linux isn't like windows and therefore, virii are
different here. Mostly, it is a question of administration. If you are a good admin,
who takes some effort securing the system, then virii are a moot point as they would
at best be restricted to a user account and therefore will only afflict something
that user can afflict. If you are not a good admin or lazy, then the picture becomes
more clouded as to what could happen.
Multi user systems like the *nix systems and (blech) NT/2000 are generally less
susciptible to virii and more susceptible to DoS type problems and trojans looking
for access to other systems. This stems from the nature of attack points. Win98 is
more prone to everyday virii as it allows access to everything to whoever happens to
be plotzing around with some CPU time such as your cousin Ted, someone with a love
problem, or Joe Hacker. References are too abundant on the web to list here, do a
quick search on 2600.com, securityfocus.com, or even slashdot.org and
32bitsonline.com. There is a lot of info to sort through though. Good luck.

It means that the program made a memory transaction to a memory address
that doesn't belong to it.
Most likely, a library is the culprit. Make sure the texpire program has
the correct associated libraries to run correctly. Good luck.

Subject: Re: Toshiba Laptop and Linux
Date: Mon, 08 May 2000 01:12:42 GMT
I'm sitting at my desk with a Toshiba T1900 with a 120 Mb HD running
Linux (Slackware 7) with some room to spare (14 Mb). (I'm not using it
for Internet access because I'm new to this and don't have it set up
yet.)
I chose Slackware rather than another distribution because I got the
impression I would have more control over the installation process and
could pick and choose what to install more precisely. I have no doubt
that with the extra space of your 200 Mb HD I could get the X Window
system installed (Slackware says the whole install of the system is
only 100 Mb.) (A project down the road is to put an X Window system on
my parallel port Zip drive.)
Looking at the Tucows site, I get the impression that a fortran
compiler, with lots of extras, would add less than 10Mb. I also get
the impression that you don't need the X Window system to run any of
the compilers; if my impression is correct, you could forget the X
Window system and have it easy on your Toshiba.
In sum, I would imagine you can do what you're trying to do, but it
will take handling the installation very judiciously. I would also
suggest trying to max out the RAM -- mine will hold 20 Mb -- to speed
things up and to minimize the swap partition -- mine is 12 Mb -- to
further save disk space. (By the way, you're right, no way you'll be
able to run KDE or Gnome.)
Good luck.

Now now, the reality here is that many OS's use ioctl and the defined values.
They are mostly POSIX anyway, which is the holy grail to most large scale
application programmers. You can't yank it cause that would break most
everything. Changing it might be a good idea, but you need consensus. Check out
kernelnotes.org and look for the Kernel discussion pages. There was a thread a
few weeks back about this which included Alan Cox.
Many OS's use ioctl, either for compatibility ChorusOS for example, or for the
actual driver interface, eg. LynxOS. These are a couple of Real Time OS's. But
Solaris and I would bet most other *nix's use ioctl as well. So, which would be
more painful? More reading and understanding, or simply abandoning a well,
albeit difficult to use, standard. I choose the learning cause it can only help
in the long run.

It's not accurate to call it a catch-all. It's simply a mechanism for writing
type-specific system calls. The kernel interface is not a function call
interface; it's a trap interface with a numeric dispatch. Similarly, ioctl
is a second level numeric dispatch for functions that are not general enough
to belong in the system call table. The ioctl library function is just a way
to get to that interface directly, in the absence of a more friendly wrapper.
Some standard library functions are just ioctl's in disguise: for example,
tcgetattr and tcsetattr.
>specific device drivers in a non-standardized way.
You seem to be missing that there are certain well known ioctl's which work
across many operating systems. For example, the FIONREAD ioctl can be used to
determine how many unread bytes are pending in a socket. This even works on
Win32 sockets, of all places (except they rename the function ioctlsocket()).

You don't seem to understand that having the source code is far better than
having documentation. In the proprietary world, you need documentation simply
because the source is not available, so people cling to the myth that
documentation is essential. Documentation isn't for dummies, it's for people
without source code. It's not an elitist assumption that developers can
understand source code.
Many programmers, like me, maintain code that is poorly documented, if at all.
Yet it doesn't bother them. Where they need documentation is at the boundary
between the software and the proprietary system interfeces that it uses. In
the open source world, you can simply view the library and the kernel as being
an integral part of your application. You do not bottom out at some proprietary
software layer that you cannot navigate without documentation.

Actually, you can often just look in the header files.
I prefer to use the online draft of The Single UNIX Specification as my handy
reference, simply to try to avoid making non-portable assumptions.

It's entirely possible that the modules you mentioned aren't modules at
all but compiled into the kernel on a stock Mandrake install. I don't
have Mandrake around to check, but SuSE and RedHat compile a metric
buttload of stuff into their default kernels.
Anyway, take out the line that says "alias scd0 ide-scsi". That probably
won't help anything. Make sure that /etc/conf.modules contains the line
alias scsi-hostadapter ide-scsi
and no other lines referring to "scsi-hostadapter". Then whenever you try
to access /dev/scd0, ide-scsi should be loaded automagically, along with
scsi_mod and sr_mod if those haven't been compiled into the kernel. Same
thing with /dev/sg0. HTH,
