I'm not sure your explanation makes any sense, unless "non-contiguous"
means something else in the Linux world than it does in the DOS world,
or in the English-speaking world for that matter. I understand
"non-contiguous" to mean bits of a single file located on blocks
separated by other empty blocks or blocks containing bits of other
files. Since files (blocks) are read sequentially, "non-contiguous"
necessarily implies a degradation in performance since more blocks have
to be traversed to read (or write) a given file.

Actually, maybe a few dozen processes, most of which have nothing to do
with reading files from disk. See response to Dances with Crows--for a

The Net is not 'for' anything. The Net is what the Net is, just like any

This was true of DOS filesystems, but is not true of current Windows
filesystems (which is why the poster reported low fragmentation on his
Windows box, which bears out my own experience, as well).

Standard redhat has not disabled it; binfmt_aout is built as a modules and
insmod'ing this module would have done the same thing -- faster and easier.

Maybe -- maybe not. inetd is something you would use on a server
and for a pure workstation it should not be needed. The problem
is when you need a hybrid server-workstation installation, and then
the preconfigured catagories doesn't match. Probably most installations
fall into that catagory.
Then again, a linux installation without inetd and the other server
daemons is more secure when connected to the internet, as the attacker
cannot get access to the system without these daemons.
p.s. It is more stupid that ipop3d and imapd is not included in
a server installation.

This is an understatement. Most of the GNU utilities are big improvements
over the standard unix equivilants; it would often make sense to install
these on standard unix systems like Solaris or AIX just to get these
improved versions. Also, some utilites like gzip are not even found on
standard unix systems.
In fact, that is how the GNU utilities were used for several years before
there were any linux system to run them on.

I have the same problem -roughly-, but with Sound Blaster 16 + Mandrake 7.0.
I have RedHat 6.2 installed on the same machine but it's never shown this message,
But Mandrake does a lot, so I have to rerun sndconfig to treate that Mandrake

I've copied redhat's /etc/conf.modules to mandrake path but it failes to solve the

The 'net isnt. But Usenet is.
If a webmaster puts word documents on his web server is his business.
You don't have to go there and download it. It's nice if he changes it
when you tell him that you can't view it though.
Usenet however, with its push design of newsfeeds, leaves you no choice.
You get the stuff people post. That's why there's certain rules and
guidelines for posting to Usenet.
Everybody posting to Usenet should be familiar with those rules and
guidelines. Everybody walking on the streets alone is supposed to know
the traffic rules!

'date' sets the OS notion of time. After this you need to update BIOS time
with /sbin/clock -w (or perhaps lookup hwclock or setclock). Must be root
