daemon is users/groups for background processes (no password).
admin is user/group/processes that have administrative priveledges (no
password).
NOBODY (I repeat, NOBODY) should be logging into the daemon or admin
users/groups. They are ONLY for background processes that the OS uses.
If you want to add a user that has administrative priveledges, you can add
'admin' to their group as well as other groups.
Again, NOBODY should be part of daemon user/group. Period.
For a better description, read the "Linux System Administration" (try
http://www.linuxdoc.org). Another book would be "Unix System
Administration" for a description of users/groups and background processes
in unix/Linux.

Aber es gibt doch bei fdisk die Option "Nicht-Dos-Partitionen löschen".

Am besten du besorgst dir Partition Magic von Powerquest - damit hatte
ich noch nie Probleme. Du kannst hiermit Partitionen verschieben,
splitten, zusammenfügen, Dateisysteme umwandeln und der gleichen noch

I got the Compaq Presario 1247 to work using TurboLinux but I
had an equally hard time setting up the X Server. However, I
finally got it going. For the monitor I simply used the default
monitor setting with the modes 800x600 and 640x480 set up.
The setting I used for the graphics card was tgui9420dgi. The
way I found this out was by trying to install with a combination
of XF setup programs. They each detect things differently and
I eventually came across the correct setting. The utilities
I used were:
XF86Setup (runs with the VGA16 server)
xf86config
turboxcfg (comes with the distro)
The next problem is getting sound and I haven't got that going
yet! Let me know how you get on.
Regards,
Michael.
PS. I've been amazed at the lack of support Compaq gives. From
what I can tell it's not just on Linux.

Mit FIPS wird noch das Programm RESTORRB dazugemacht. Damit kannst du,
falls du vorher bei der Frage, ob du die alten Partitionsdaten speichern
willst, mit ja geantwortet hast, diese wiederherstellen und hast danach
deine Windows partition mit Daten drin wieder, wenn ich mich nicht irre.
Du musst dann nur noch die Sicherungsdatei angeben (wahrscheinlich
Rootboot.000) und hoffen das das klappt. Natürlich brauchst du dazu die
Fips-Bootdisk mit den Sicherungsdateien drauf.
Wo hast du denn FORMAT C: eingegeben? Hat er dann tatsächlich
irgendetwas formatiert? Wenn ja, dann ist da natürlich wenig Hoffnung,
das da noch irgendwas ist. Aber probiers halt aus.

I probably have the same type of Maxtor (27G series 6800), and
it does run hot. I tested with the drive placed outside of the
computer and a room temperature of 22-23C. The aluminum body
eventually reached 50C, and during reads the small square chip
marked 'Lucent' reached 65C, and it seemed to get hotter with
PIO than DMA, but I'm not sure. The large DSP chip next to it
didn't get quite as hot, but I don't remember my measurements.
Maxtor told me that the Lucent chip is designed to withstand
such high temperature. The tiny chips at the front of the PC
board also ran hot, and I was told by another party that they
drive the head voice coil and the motor.
The Lucent chip cooled down to 40-45C when I mounted a fall fan
next to the PC board or when the drive was mounted vertically.

I would be very surprised.
AIX is IBM's UNIX. It's a fairly traditional UNIX whose API is a hybrid
of SysV and BSD (much like Solaris, HP/UX and many others are.) IBM
sells (or has sold) it for every platform they ship - s370/390
mainframe, AS/400 mini, RS-6000 workstation and PC/PS-2.
As far as I know, there has been no cross-development between A/UX and
AIX, except for the stuff that everybody in the world already uses.
As for the user's point of view, the two systems are radically different
- A/UX uses a Mac-like desktop, which AIX uses a traditional X11 server
with a window manager.

Not quite.
RAID level 4 (I think it's 4) uses a dedicated drive for parity
information.
RAID level 5 stripes parity across all drives along with the data.
But you are correct that one drive's worth of storage will be used for
error recovery (usually parity) data in any RAID5 array. This means 1/3
of your storage if the array has 3 drives, 1/5 of your storage if the
array has 5 drives, or 1/9 of your storage if the array has 9 drives.

If you really want to do this the browser way you should search the
apache documentation for how to install apache. Then you will need to
learn some simple shell programming and write yourself a cgi-script.

For a basic card, anyway. Which is all you need for slow devices like
CD, tape and removable-media disks.
OTOH, for hard drives, you need a high-performing card (Ultra-Wide,
Ultra2, or Ultra3) to match EIDE's performance, and those cards will
probably cost you between $100 and $300.

Keep in mind that the original poster already had a strip-down SCSI card
from another device, so he'd be replacing one card with another. In
other words, he's not giving up a slot.

times longer than normal to boot. When I'm asked to insert the root-disk it
loads it happily, without being slow.. After it has loaded, the kernel says
"bus-error" four times, before it tries to go down.. it hangs, when it tries
to reboot.. Have to reset it manually.. I have tried aha1542 bootdisk and
no_pci.s bootdisk.. both detects the scsiadapter and it's drives fine, but
then this "bus-error" comes. Anyone knows what it means? What can I do about
it? The computer runs win98 quite happily, well it swaps a little bit.. ;-),
but I have noted no stability problems yet in win98..
Maybe I should mention that the mobo has got apm- capabilites, could this be

Yes, but it's not usually a problem. The device files run from /dev/hda
to /dev/hda63 for IDE, meaning you can have 62 partitions. (3 primary, 1
extended, 59 logical.) SCSI disks are limited to 15 partitions. This is
usually enough for most peoples' needs. If you really want more
partitions than that, I suppose you could hack the kernel source or check
out devfs....

Not true. Drive size is unrelated to temperature.
Temperature of the chips is a function of the speed the chip is clocked
at. This should be 33MHz or 66MHz for a UDMA drive. If you overclock
the IDE bus, then you're overclocking the chips - possibly causing
overheating.
Temperature of the drive mechanism itself is a function of the spindle
speed (7200 RPM runs hotter than 5400 RPM, and 10,000 RPM runs hotter
than 7200 RPM) and the number of platters in the case.
As for where you should mount the drive, the answer is any place where
you get enough airflow to keep the drive within its normal operating
temperatures. If you do this by placing it in a 5.25" bay alongside
some extra fans, then that's fine. If you place it vertically at the
front of an ATX case (where Dell and Micron put their drives), that's
also fine. If you leave your case wide open and aim a 15" fan at it,
that's also good (albeit inconvenient.)
One importatnt thing to keep in mind is the direction the air is flowing
through your case. If you add a fan that blows in the wrong direction,
you may end up impeding airflow instead of increasing it. This will
cause your heat problem to get worse!
In other words, if you're having a problem, you've got to think about
what you're doing. Don't just throw fans at a problem and expect it to
go away like magic.

use /dev/fd0h360
d360 is for 360K drives
h360 is for 360K disks in 1.2M drives
man fd(4) for more information.

See the man page for fd(4).
H360 is for formatting a 360K disk in a 1.44M 3.5" drive.
You want h360 for a 360K disk in a 1.2M 5.25" drive.

It depends on your hardware architecture.
For X86 PC hardware, you can have up to four primary partitions.
You can designate one of these primary partitions to be an extended
partition. Extended partitions may contain an unilimited (up to the
number of /dev entries for the drive) number of partitions.
Partitions 1-4 (eg: /dev/hda1 ... /dev/hda4) are the primary partitions.
Partitions 5-16 (eg: /dev/hda5 ... /dev/hda16) are partitions that are
contained within the extened partition. DOS/Windows calls these
"logical drives".
For other architectures (SPARC, Mac, etc.), there will be other limits.

Actually, bigger drives are sometimes cooler, because they have newer chips
with lower powers. In some cases (no prunch intended), disconecting the
fan leads to lower overall temperature. The fan itself makes approx. 10W
of heat.
