I have no idea what the included message was - as my text only news
reader doesn't handle that.
But the message header saw 'well intentioned'. Beware of anything
you read. There are some people who will give you instructions on
purpose to trash a system.
A few months ago someone on a BSD group asked for help on an
install, and one poster "The Reverend Don Kool" - who preaches that
you should never run *IX on any iNTEL platform actually told
the poster to
cd /; rm -rf *
The poster did this - found out the hard way - but took it in
stride.
Trust nothing that you read unless it makes sense. If it doesn't
make sense, or you don't understand what the command is doing,
don't do it.

Yes, from the swapon(2) man page:
Swap pages are allocated from areas in priority order,
highest priority first. For areas with different priori-
ties, a higher-priority area is exhausted before using a
lower-priority area. If two or more areas have the same
priority, and it is the highest priority available, pages
are allocated on a round-robin basis between them.

Subject: Mandrake and 3D Labs Problem
Date: Tue, 19 Dec 2000 02:38:10 +1100
Hi everybody, I am desperate to get this box working
I installed mandrake 7.2 everything went fine in the install
routine and the open GL display looked great while this
took place, the resolution was fantastic.
I installed lilo because I'm dual booting between win 98 and mandrake 7.2
there is no problem through the boot process only when it tries to start the
X Windows I get nothing on the screen at all, only the mouse cursor which
works fine. When I installed it I chose 1024x768 at 4 billion colors I think
it's almost as if the windows are there but the resolution is to high.
I have a 3D Labs Oxygen VX1 Graphics Card, I can get in to the command
interpreter but I don't know how to change the resolution from there.
Can anyone please help me with this problem?
Thank's in advance!

This is almost certainly a problem with Win 98. I can't think of
any way lilo would give you such a message. There is something wrong
with the boot sequence for Windows which occurs after it gets started.
You can try looking at files like autoexec.bat and config.sys,
although I thought those were not necessarily used during the W98
boot process. Also see if you can find the command processor.
In the end, you may have to reinstall W98.
If you can boot LInux, you should be able to mount the W98
partition and look at it.
What happens by the way if you enter
C:\WINDOWS\COMMAND>COM
at the prompt?

Depends on your programming level I would guess. If you are just starting
out, it seems that everyone writes a mail application in perl at first.
Some sort of right of passage. If you are more seasoned, do something dead
sexy involving integration of a computer into anything. (IP over anything?)
Some of my favorite things to play with are computers where computers
shouldnt be, www.mp3car.com has a lot of examples of people shoe horning
PCs into cars with some really bitchin results. Or how about a home
stereo MP3 player with a twist, instead of broadcasting different streams
over wires to different rooms, broadcast over FM channels locally so all
you have to do is tune in to whatever format you want from any radio in the
home, just watch that output power. I think I may go home and do that one
myself. Just think of something that would make your life more convienent
and then decide if their is any way to work Linux into the mix. That whole
Mother of All Invention thing..

This means that gzip is seeing in the test file some extra data that
can't be interpreted as gzip-comressed data. Maybe ssh is adding
something to the output stream, like welcome messages etc.
Try ssh -q (quiet). Also try whether this results in the same message:
tar cOphz <directory> | (cd /tmp; tar xzf -)
(delete the stuff from /tmp afterwards).

If you have other resolutions selected, you can use CTRL+ALT+- and
CTRL+ALT++ to switch between them.
Else, when you get to the lilo boot, type "linux 3", which will bring
you into console mode. login as root, and run your X configurateur again
("XFree86 --configure", I think), choosing a smaller resolution.

Yeah, like anybody cares! 4.75 checks anyway, especially from the BACK
button. Moreover, it ignores maximum cache size and occasionally destroys
the history.dat file, which is -- to somebody's eternal shame --
unsearchable unless you write it to a file and then search that, which is a
nuisance.
It would be really handy to go back and look at the stuff that's stored in
the 19 meg and growing cache file without being on line, although
cablemodem makes it less essential. Just being able to FIND stuff there
would be a good thing. I hate having a mess of saved files hanging around
just because I think I might want to look at them again, especially since
they're already saved in the cache.
