Looking at Google I found The Biostar Geforce 6100-m9 NVIDIA Socket
939 micro ATX USB 2.0/ Serial ATA/ RAID for $65.00 and a barebones kit
with mb and cpu and case 350 watt ps for $130.00.
It has a floppy drive and serial port on the mb. With all the other
stuff. This would be my cheapest new computer unless you know why it is bad.

I've got a Fedora 7 (x86) system that started exhibiting truly bizarre
behavior about a week ago. Basically, the clock stopped working. If
I run 'date' it shows the date/time from a few days earlier, and it
*never* changes. If I touch a file, it has the date/timestamp from
the time/date in date output. The odd thing is that this behavior
only happens when the system sits relatively idle for a long chunk of
time (at least 24 hours). If i'm actively using it every day, then
its fine. If I reboot, then the problem goes away (and the system has
the correct time after rebooting).
The first time that this happened was last weekend (Aug 18), and I had
to reboot it last Monday (Aug 20) to fix the problem. Its now
happened again. At this moment in time, date claims that its Sat Aug
25, even though its actually Sun Aug 26 right now.
To make matters worse, the system behaves oddly when this problem
occurs. I suspect its because anything that relies on getting an
accurate (or changing) clock is failing. If I attempt to reboot
cleanly, it just never happens. The system acts frozen in time.
I've checked dmesg & messages, and there's nothing there. messages
just stops logging anything around the time that the clock appears to
Anyone ever seen this bizarre behavior, or have any ideas what might
be going on?
I was talked into using LABEL's because they make it easy to add new
partitions and such. I have a bunch now and they work fine.
Alas, now that I am making 2 hard drives with the exact same F7 on
them LABEL is causing me all kinds of problems. Even the F7 Rescue
So the only fix is for me to go back to exact partition names so I
can continue to get my understanding of dd complete. I think dd will
work fine IFF the partition your sending data to is larger than the one
it is coming from, and you do NOT put a file system in the destination
So all my LABEL's are going to disappear.

I have a number crunch application that is starting to hit bottlenecks
in standard maths functions, like log, exp sqrt etc. Thing is, in many
places I don't need much precision, so was wondering if there was
anything I could do, like use a different library or enable some gcc
options (currently using -O2) to speed things up.
Does anyone have any recommendations for fast maths ? search around on
the web I've found a lot of references to fast / approximate math
libraries, but nothing obvious.
Since I upgraded my FC6 box from kernel-2.6.20-1.2962.fc6 to
kernel-184.108.40.206-32.fc6, and now 220.127.116.11-42.fc6, I am getting pauses
from the whole OS. They last ~1 second and occur every few minutes.
Every application becomes unresponsive for the duration. The 1 second
scheduler latency this causes is long enough for my music player to be
effected and the audio track to be interrupted. This makes the fault
very easy to hear. At the same time kernel thread events/0 seems to
use all the CPU time. Here is the first few lines of top's output
when a pause happens:

Has any one else seen this issue?
Does anyone know what kernel thread events/0 does?
Could this be related to CFS newly introduced into Fedora's kernel 2.6.22?
Can anybody suggest how to fix this issue?
Ok I switched from Windoes Xp to Linux and got Fc6 installed in which
im using right now but earlier I bought the next version of Fedora
which is f7 but it wont boot from restart or start up and the reason
I bought was becuase I couldnt download anything from the internet at
all! Only from like Add/Remove default program and the updater!
Can anyone help before I give up Linux!!

Has anyone been able to get this working? All I get is a resolution of 1280 x

I gave my wife a Canon Elura 100 camcorder for Christmas. I just watched
her download her very first movie to Windows XP. Can I do the same in
Fedora Core 5? If I just plugged in the camcorder to my onboard 1394
port, will an application come up recognizing the camcorder and offering
to download the movie from the DV tape?
If you want to copy something big from one partition to another the
old dd method is for you. You have to do it right. This means that:
1. The destination partition MUST be at least a byte larger than the
source partition where the data is coming from. This is essential!
2. The dd copies everything including the file system.
3. Be ready to check the file system of the copy with fsck.
4. If you are making a copy of an entire working Fedora system make sure
you change all the entries in /etc/grub.conf and /etc/fstab files to the
new partitions of the copy before you try to run it.
5. To copy a partition from the source, called /dev/source to a
destination partition called /dev/destination use the standard dd form:
# dd if=/dev/source of=/dev/destination
6. Always run dd in the source computer.
7. Take your time doing all this. It will save you problems later. There
are a lot of ways to make errors.
8. Think of how dd works this way, dd see's the source partition as just
a pile of bytes. It takes a few bytes each cycle and puts those bytes on
the destination partition. When done dd reports how many bytes it found
and how many it put on destination. They are the same large number.
