Maik,
the most accurate way of time measurement on PC
I know of, is to read CPU performance counter,
which has better than 1 microsecond resolution.

The question was not immortality, but bankruptcy. There is no person or

like asking "Could sliced bread go bankrupt".

Subject: Logical Partitions are toast
Date: Sat, 23 Sep 2000 01:27:23 GMT
Hi there,
You can call me an idiot, because I should know better. Here is my
situation: I was consolidating my disk space so that I could store some
bigger files. I had enough space on one of my Linux partitions to back
up 2 of my Win98 partitions so that I could blow them away. I had
created this Linux partition at the very end of the disk (Cylinders
970-1232) in a Logical partition because Windows really sucks and won't
let you create multiple partitions as Primary. I backed the 2
filesystems up and removed them with Linux fdisk. I then created the
new partition (a FAT32 partition) in Linux fdisk. I booted to Windows
to format the new partition. Windows saw 2 drives because the new
partition happened to line up exactly with the old partitions. So, I
started up DOS fdisk (big mistake, in retrospect) and it told me I had
no Logical partitions. So I created one, because it saw the correct
amount of usable space in the Extended partition. Now, when I booted to
Linux, it did not like me at all and besides that, DOS has somehow
switched the partition numbering scheme. It had also pushed the Linux
partition into LaLa land (Cylinders 16xx-19xx or something like that).
I was quite dismayed, so I started playing and thought I might just fix
it by reconfig'ing with fdisk. I set the partitions correctly again,
but e2fsck did not like that either. I have tried using "gpart" to look
at the partition table, but it won't fix extended and logical
partitions. Anyone have ANY clue? Please? This is beyond me.
Thanks a trillion times in advance...

Subject: Locked sound device
Date: Fri, 22 Sep 2000 21:41:41 -0400
Hi,
I finally got my sound card to work under Storm Linux (Debian Based) and
I was listening to
Sara Brightman. For some reason I had to reboot the system and in my
moment of genius, I let the CD ROM keep right on playing as the system
shutdown; I wanted to see when it would cut out.
Well now it's cut right out. I got the sound working in the first place
by following the documentation for sound in
/usr/src/linux/documentation/sound/introduction.txt. And it worked
perfectly.
Now when I try and issue the same commands:
insmod soundcore
insmod soundlow
insmod sound
insmod uart401
insmod sb io=0220 irq=05 dma=1
it claims that the device is busy. My guess is that there is a file
somewhere that the system sees that usually indicated that the card is
in use. A lock file or something.
If someone has done this before, can you tell me how to clear this?
Much thanks in advance.

Here is the equation:
X --> P --> E
[X] You install software from some source (installation disks, files
downloaded from the web, type it in from memory, a backup tape, whatever)
.....
-->
[P] Onto your hard disk. That is where software goes, into some persisted
storage that implements the program store for a computer system. Why a
program store? Because the nature of computer systems is that we want to be
able to turn them on and off, survive an application crash, etc. But at
some point, we are interested in using the computer system...
-->
[E] And we go into the execution environment, defined by everything that we
have installed, and run our operating systems, applications and whatever.
What part of this do you disagree with? It is this observation, and the
natural separation it implies, has implications for all the groups I posted
to.

Reply-To: [EMAIL PROTECTED]
Just wondering if anyone succeeded in putting Win98+Linux+FreeBSD all on
one very large boot (27GB) drive? Booting to Linux anywhere on the drive
is no problem using a small /boot partition first, then Win98. My first
attempt at putting FreeBSD 4.0 after Linux taught me that FreeBSD will not
boot beyond the 1024 cyl limit.
Ok, so I dropped the FAT32 partition to under 8GB followed by the bsd
slice with / ending < cyl 1024 and FreeBSD was able to boot. As an
experiment I then tried creating an extended partition with a FAT32
logical and it overlapped and wiped out FreeBSD. The Linux+FreeBSD
mini-HOWTO said Linux install kernels don't usually have UFS support, and
would probably do the same thing, So I bought another drive for FreeBSD
and backup. But I still wonder if this would have been possible?
I may still try Win98+Linux+FreeBSD on my laptop, since it would be easy
to keep / below cyl 1024, even near the end of a 1099 cyl drive.
Although, fdisk UFS support in RH 6.1 seems unable to read disklabels of
slices that run beyond the 1024 cyl boundary for some reason.

I heard that there was some sort of free version of Oracle 8i for Linux,
presumably with restrictions for non-commercial use. I also heard that it
was an extremely popular download. All I want it for is to teach myself how
to install, manage, and use Oracle.
I've looked on their website several times, starting with their homepage,
and haven't found it yet.
Does anybody know anything about this?
Thanks.

vi ( or vim, I should say ) are just as capable of understanding the
language that the programmer is using. elvis and other vi clones offer
similar services to vim, but generally to a slightly lesser degree.
I will admit that vanilla vi can be dim-witted compared to vim, but
I would put vim right up there with emacs as a programmers editor.

Despite people's concerns about cables and termination, the problem is

Did you just buy those drives from onsale.com or something? They look like
the pair that I bought. The instructions accompanying the drives said that
they'll need to be formatted, which is what I did.
Check your system to see if you have a "scsifmt" package or program. I
didn't, but downloaded one from a Redhat contrib mirror.

I have a RH6.1 install on a laptop. The combination of buttons on the mouse
pad pastes selections in the usual Unix manor. I have a RH6.2 install on a
desktop. The desktop has a M$ scroll button mouse. That mouse does not
paste a selection. I have poked around the /etc/rc.d/* looking for help and
read many things. I am stumped. The main seemingly relevant difference is
that /etc/X11/XF86Config for RH6.1 (laptop) has
Emulate3Buttons
whereas
XF86Config for RH6.2 (desktop) has
# Emulate3Buttons
I guess I don't want to emulate anyway sense, I have three buttons. But
setting the Emulation to yes does not seem to help. Using KDE on both
machines.
Thanks for any suggestions

'shutdown -r now' is the proper way. What is probably wrong is you're
missing the script to unmount everything. Do you have the same problem
with runlevel 0 (halt), or just runlevel 6?
does /etc/rc.d/init.d/halt exist and do it's soft links exist too?

-rwxr-xr-x 1 root root 3260 Mar 8 2000 halt

The latest versions of Mandrake and SuSE at least include USB patches
in their stock kernels, which should work well. You can get these from
http://cheapbytes.com/ for very little money, or find a Linux-using
friend with a CD-R(W) and have him/her burn you a copy. Very few
distros use fvwm as a default these days. BTW, the GNOME that shipped
with RedHat 6.0 is insanely buggy; avoid it if at all possible! The
latest GNOME from Helixcode is much improved. If you must use one of
the CDs you have already, try the Caldera one... Debian is a great
distro, but its install is not that friendly for newbies and 2.1 is
pretty old.
Asking questions like "Is GNOME or KDE better?" is likely to start
religious wars. Most distros include both; install both and try them
both out so you can decide for yourself which is better.
