Come to think of it, I have had bad experiances with several pieces of
hardware that has caused the similar problems.
* Defective DIMM caused the Kernel to "Page fault" and dump CPU regs to
the console and lock after heavy use.
* CPU malfunction via overheating, while cracking RC5 keys for
www.distributed.net, this caused my system to reboot :(~. My solution was
to use thermal paste between my CPU and it's heatsync.
* Power surge caused the power supply to turn off my box (I assume it's
the current threshold) and not come back on for like a delay of 30Mins.
Eventually the power supply burnt out, (apparently it could generate
250Watts of power) I then bought a new case which had a 250Watt
powersupply mounted already.
After that fieasco, I have experianced extreame stability for a good few months.
Hope I helped :)

Support for the Geforce line of cards *should* be present in XFree86
3.3.6 (the current "stable" release), and it is definately supported in
the 4.01 release. You would need to both upgrade to 4.01 and download
the appropriate GLX and kernel tarballs in order to make use of its
OpenGL support (i.e. games).
I've been using this setup for my TNT2 and it works quite well. After
reading some reviews, I'll be picking up a Geforce2 MX just as soon as I
can find one.
Go get that sucka.

Subject: Linux laptop and projector problem

Hi,
I tried using my Linux (Mandrake 6.5) laptop with an LCD projector.
There is a Fn key that switches the video output between various
outputs. When I press this key I get a distorted display (it's as if
a portion of the display was sliced out vertically and repeated sude by
side --- i.e if screen display was A B C D you would see A A A A)
Pressing the key again freezes the machine requiring a power down to
reboot.
Does anyone have any ideas where I might start to try to get my
Linux laptop working with this projector?
Thanks,
DS

Hmm...one thing I noticed was that you're running an SMP kernel on a
non-SMP-capable system; this probably doesn't make a difference one way or
the other, but why are you doing this? Assuming that your drive is working
right and you don't have something hogging the processor, you shouldn't be
having these problems. I have a BTC BCE621E (?) 2x IDE burner in a 450-MHz
K6-III box, and the only time I've burned a coaster was when Win98 locked up
during a burn. I've never burned a coaster under Linux. I've used Maxell,
Sony, Memorex, and several no-name CD-R and CD-RW media with it, and the
only problem that's popped up was that one of the no-name CD-Rs was
unreadable by one of my older CD-ROM drives (a Mitsumi 6x CD-ROM, IIRC...and
given that it's a Mitsumi CD burner that you're using, I'm beginning to
wonder if there's a pattern of problems developing here that centers around
their hardware).

Sure it is. You are not recompiling the kernel(you *could* update the
system to the latest development version every night and recompile but
it wouldn't be very stable :-) Rather, you are updating the ports
collection -- the application index. Basically, the way it works is
that there is a directory /usr/ports which has subdirectories with
programs divided by categories. Each directory contains a makefile
skeleton and the patches needed for a smooth compile. To install
gnome, all you have to do is cd /usr/ports/x11/gnome and run make
install. It will fetch all dependencies from the internet, compile
all the libraries and programs and install it for you. Easy, clean,
quick. By updating the ports, blowfish means updating the skeletons
to reflect the newest apps.

IMHO, it is not evil(and, frankly speaking, I wish I tried to do a
binary install of mozilla on my old 166; the compile took forever but
apperently, the startup took even longer :-) However, with all things
equal, why not compile from source? You'll get a little extra
performance from custom switches. You can tweak the program if
needed. . .

Fine. Install packages. I, personally, believe that freedom is
freedom to choose. Packages have their place and if you are not
interested in hacking around but rather need to get something done, I
can easily see how a package might be better than compiling source
code for you.

As I see it, RPMs/packages are for people who need productivity and
who are not sysadmins/etc. Both packages and source compiles have
their place. It's up to you which one you want to use.

"make bzdisk" essentially executes the following command:
dd if=arch/i386/boot/bzImage of=/dev/fd0 bs=8192
This command copies the kernel image directly to a floppy disk, with no
filesystem or anything. This allows you to boot from the disk in a very
simple way, but it wipes out any filesystem on the disk, so you can't
access that disk in the normal way.
If you execute the following commands:
fdformat /dev/fd0h1440
mkdosfs /dev/fd0
then you will lowlevel format a floppy disk and create an MS-DOS
filesystem on that disk. After that, you can mount the disk in the
normal way and copy files to and from it using just about any machine.
Linux boot floppies are often a bit of a special case; if you want more
info than you ever will need to know, visit:

1024*768*32=3M, so there should be no problem running at 1024x768 at
32-bit color. Check your XF86Config; after the line that says "Section
"Screen" ", add the line:
DefaultColorDepth 32
and see if that improves things. For whatever reason, RedHat's
automagic X configuration doesn't configure anything but 8-bit color,
which is just plain silly in these modern days. Or run Xconfigurator as
root and make sure you configure modes for 32-bit color...

Many CDs (especially burned CD-Rs) have an area at their very end that
contains unreadable blocks. When the cp command tries to read those
unreadable blocks, it spits out errors like that even though the command
has read everything correctly and such. There's a program called
"readcd" that comes with the cdrecord utility which can read CDs without
generating those errors. readcd also may work better for copying
scratched/damaged data CDs. If that's too much trouble, try this:
dd if=/dev/cdrom of=cdimage.iso bs=2k
HTH, good luck.

FWIW, I use a Mitsumi CR4802-TE IDE CD-RW burner under the Linux
2.0.38 non-SMP kernel (on a single processor machine) and CDRECORD 1.9
without problems. I've burnt several audio and data CDR and CDRW disks
without making a single coaster (using Shark CD-RW and Memorex CD-R
disks).
I have upgraded to the latest microcode, but even with the original
microcode, I had no problems with creating CDRs on the Mitsumi drive.

Hi Mario,
I see for first time that somebody (you) use cp to make disk image. There is dd
command which used for this purpose. Just use
dd if=/dev/hdd of=disk.img
Hope that it will not produce errors.
