It's treated as a hard drive. It's /dev/hda or something (NOT
/hda0!). Iomega usually formats a partition which is labelled #4 (not #1 for
some reason) so try mounting /dev/hdb4, /dev/hdc4/ or /dev/hdd4, depending on
which drive controller your zip drive is on (assuming IDE, of course).

I just went to http://www.ibm.com/ and put "rs6000 linux" in the search
box. It came up with 100 hits. Look around on the IBM web site and you
should find what you need to know.

Is this a SCSI or IDE drive? I'll assume IDE and go from there.
BOot the system with "linux hdX=ide-scsi" . X is "a" if the drive is
the primary master, "b" for the primary slave, "c" for secondary master,
"d" for secondary slave. Most CD-ROM-type devices are put in as
secondary masters. Or if you're not sure, do a "dmesg | grep CD" to
find out where it is.
Once that's done, log in as root, and do:
modprobe ide-scsi
modprobe sg
On reasonably modern distros, this should be all you need. Then, the
command "cdrecord -scanbus" should tell you that it's found a CD burner
somewhere. cdrecord is very flexible, but it's command-line oriented.
xcdroast/gnome-toaster have GUIs. Oh yes, if this doesn't help,

? Next time, post the exact error message you get; "superblock cannot
find hard disk" is not an accurate description of whatever the problem
is. Please post a transcript of the commands you're using here, and
include the complete text of all error messages.
Anyway, if you're backing up your system, I assume you're doing
something like this:
# mount /dev/hdXY /mnt/backup
# tar czf /mnt/backup/backup.tgz /home/ /usr/local/ /etc
# umount /dev/hdXY
If this removable drive is listed in /etc/fstab without the "noauto"
option, then the init scripts will try to mount the removable disk at
startup. If the removable disk is not there, the mount will fail, and
you could see a message about not finding a superblock. This should
*NOT* halt the boot process. Put the "noauto" option in for the
removable drive if it's not there already.

Thanks, but still no luck. I know I'm doing (or not doing) SOMETHING stupid,
but I can't figure it out.
I tried:
echo -e "\f"
echo -e "\f" > /dev/lp0
echo -e \f > /dev/lp0
echo -e '\f' > /dev/lp0
(did a "cat testfile > /dev/lp0" before each one, too)
If I do a "cat /dev/lp0" I get:
#DWS:NO;DOC:4,00,NO;DSC:NO;DBS:NO;
What might that indicate?

PCI cards can share interrupts, and Linux supports this feature of the
PCI bus. This has been true for a couple of years now. WRT the weird
message you get at boot time, try using the 3c59x module instead of the
3c90x. I have had nothing but trouble using 3c90x for the 3c905B and
3c905C NICs. YMMV, of course.
The main thing to remember about IRQ sharing is that having many devices
on the same IRQ degrades performance. If there are 3 devices on IRQ 10,
whenever IRQ 10 is triggered, the kernel has to determine which device
requires attention, then activate the handler. If all of the devices on
IRQ 10 are Ultra-160 SCSI controllers generating 100+ interrupts per
second... well, you see where this is going. My NICs seem to generate
fewer IRQs than the serial, parallel, soundcard, and IDE interfaces, but
more than the keyboard. Don't know for sure about USB; I have no USB
devices at present. HTH,

usenet isn't write only and I can't conveniently do that.
You need to install the ppa module first (using insmod)
THen I think it's /dev/sda4. There's a HOWTO that
goes into depth. (note that with that distro, you
do *not* need to recompile the kernel, support is built
in.)

Subject: Setting up parallel tape drive
Date: Thu, 15 Feb 2001 23:49:39 -0600
I've got an external parallel port tape drive (ditto 2GB) that I'm looking
to set up on my RH7.0 box. According to the hardware compatibility
howtos, this drive should be supported by ftape version 3.x and up and I
currently have 3.04d installed (default with RH7 I think). Anyone know
anything about this configuration? The ftape module installs ok (messages
output below), but I can't seem to access the drive in any way I've tried
so far. It's possible that my parallel port isn't set up correctly since
I've never actually used it under linux... what settings are supported
(ECP, EPP, etc). Any insight would be appreciated.

Hi,
I've some trouble with the Scorpion Tape drive and a Vortex RAID
controller. I get a SCSI error (syslog below) when I insert and rewind
the tape and the next operation is a read. Rewind and write a small
file is my workaround. After that the drive works fine. Has anybody
seen this?
The drive is forced to SCSI 2, but can do SCSI 3. Would changing this
do any good? The reason to wasting a whole SCSI RAID channel for a
single tape drive is LVD.
Thank you for your ideas.

Beats me why people are so concerned with CPU speed when it's arguably
common knowledge that CPUs are still waiting for graphic card and hard
drive power to catch up to them.
Moreover, if $100 Canadian is such a huge deal to you, what are you doing
playing with DVDs?

Oh, the idea behind that "if you're serious about watching DVDs" quote of
mine didn't originate from me. It came from Maximum PC...
"Lines are as sharp as they can be on a TV, but viewing on a computer
monitor delivers a picture so sharp, you�ll actually prefer to watch
movies on your PC" (go to Maximum PC's online review database and enter
the word 'realmagic' in the Product search line)
...as well as other well-known publications such as PC Gamer.
