partitions are /dev/hda5, ..hda6 ..hda7. 5 is boot, 6 is /.
I had made a rescue disk; didn't understand I needed a bootdisk other than
the default install bootdisk. Found a ref to mkbootdisk in the ref guide;
re-connected the 6.1 server-class install HD in what's to become a FreeBSD
box, man mkbootdisk and then made a bootdisk from that. Successfully
entered rescue mode. Did e2fsck /dev/hda5 and then 6 and 7. hda6 first
reported UncorrectableError on a sector, however, subsequent re-run gave a
clean report. hda7 turns out to be swap, which can't be fsck'd. after
this, I decided to try re-booting one more time; what I thought was a hang
was just taking a long time before giving up on mounting NFS (some error
message there about RPC; far as I know, I don't have any NFS
mounts active). After this gave up (I fell asleep for a couple
minutes at the console, so didn't try to shut down so it had a chance to
time out and boot continued) booting continued, the box is back up for
now.

/sbin/lilo
There could also be a problem with device codes. You may need
disk=/dev/XXXX
bios=0x8?
To correctly assign the device codes.
The boot installer (21.6 and later) can tell you about device codes with the
-T diagnostic switch
lilo -T help
lilo -T geom
should give you geometry and device code information.
lilo -v3 will tell you what device codes lilo is trying to use when it
installs the boot loader and map file.

Subject: Problem mounting ZIP 250 USB drive

Hello all,
Hello all,
When I try to mount my ZIP USB drive (mount -t vfat /dev/sda
/mnt/usbzip) with a PC formated disk (empty or full), I get the following error :
mount : type fs incorrect, incorrect option, incorrect superblock on /dev/sda,
or too many filesystems mounted.
The drive light flashes and I hear the drive starts to spin but it just
gives out that error message. Anybody have an idea ?
Note :
_ I have all necessary USB options enabled in kernel (no modules)
_ I have the USB device filesystem mounted ok (entry in fstab), i can
see the entry in /proc/bus/usb
_ I have set the necessary options for scsi. I can see information on my
device in proc/scsi/scsi.
_ I have created a usbzip directory in /mnt.

Problem.
Check each and every file on hda6, against the rpm database or something.
I had an odd situation here when i hit the reset switch once.
A binary got corrupted., and had to be replaced.
You might want to split the system into several partitions.
/boot
/
/root
/tmp
/var
/home
/usr
This way, if something in the /usr part gets screwed up, the / ( root ) is
not affected, and you can repair it fairly quickly.
With your current everything-in-one-partition setup, corruptions in /home
or other non-root) could cause you unnecessary complications.

I agree that Xinerama creates one large desktop that spans multiple
monitors, which allows you to drag windows from one monitor to the next.
However, when windows maximize to take up the entire desktop, the maximized
window will extend into every monitor, and this is quite a nuisance. Most
people who have multiple monitors display different windows in different
monitors, so windows "should" maximize to fit only one monitor. According
to Xinerama How-To, Enlightenment can handle multiple monitors in Xinerama
and maximize windows to fit one monitor, and not extend into other
monitors. My point in the previous post was that when I upgraded to Ximian
GNOME, Sawfish was still the window manager, however, now, windows maximize
and fit into only one monitor.
There's one problem, though, that I forgot to include in the previous post.
I have two monitors of different sizes, and placed them side-by-side; the
larger monitor is the primary monitor. When I maximize windows in the
smaller monitor, the horizontal width is correct, but the vertical height
is too long; height of the larger monitor.
Does anyone know how to correct this problem?

There's a couple of other solutions:
rm -- --atime-preserve
or
rm -i *
*** Don't forget the -i or you'll be REALLY sorry ***
It'll ask you about each file in your directory, one by one... actually,
come to think of it, don't use this one for your particular problem. If
you accidentally had created a file "-rf", it would be bad. I just
recalled when I use this trick: when the filename has unprintable
characters in it.

I thought cave art showed spirituality in the only language they could

Yup, could do, but hopefully, it's just /sbin/lilo and go... I wouldn't
think you'd need anything else unless there's a EIDE drive hidden in this
some where. If it's just SCSI then it shouldn't be that complicated.

Yes, I finally figured this out although I settled on QUANTA2 which at
least makes an attempt to be for those of us who are not programmers. With
it I believe I can muddle my way though the site update.
Thanks. I just didn't want to have to install a text editor, learn how to
use it, install an ftp program, learn how to use it. Linux is wonderful
but sometimes trying to get any work done is a bear.
For example, I wanted to change my logo so I decided to install the GIMP.
7 meg rpm download. My package amanger complains that it won't handle
anthing with major number => 3. Downloaded 3 new versions of RPM to no
avail Now in the process of downloading theGimp sources 12 megs. No doubt
when I try to compile it, something or other will be missing and I'll spend
more time plinking around.
There's something to be said for just going down to the Office Depot and
buying a program in a box.

I have the same CD-RW drive as you and probably the same DVD drive
(Pioneer DVD-105S) and I'm having a similar problem...
I'm using kernel 2.4.2 and SCSI-emulation for the two drives, which are
hdc and hdd respectively. I can mount and read discs just fine in the
Pioneer drive. When I try to mount the same discs in the Plextor drive,
I get mount's generic "wrong fs type, bad option, bad superblock, etc."
message.
I switched back to plain ATAPI (rmmod sr_mod and ide-scsi and insmod
ide-cd) and tried again. The Pioneer drive still mounted things fine, but
the results with the Plextor were less predictable. I once got it to
mount successfully and read the root directory, but trying to "ls" a
subdirectory on the CD returned garbage. For the most part, any attempt
to mount or unmount would result in a bunch of kernel messages saying
"status error", "status timeout", and "irq error", and a few ATAPI
resets.
Now, the really interesting part: under kernel 2.2.18, _it works
perfectly_. Is this a driver bug, or something that needs to be
reconfigured, or what?
My motherboard, btw, is an Asus A7V, different from yours.

Let the install do whatever it does, but once it is finished,
part of customizing your system can be to change whatever the
install did, to what you want. The only thing you _don't_
want the install to do is make a separate partition for /tmp,
unless of course you want it to stay that way (and I can't see
any reason one would want both a /tmp and a /var partition).

It is very difficult for me to suggest what would be best for
you! It might be that for you, one big partition actually is
the best. Certainly if you want to learn "proper" (whatever
that is) UNIX systems administration you will want a number of
"unnecessary" partitions. You might want two or more root
partitions, each with different distributions on them, as an
example.
Personally, I would _at least_ want a separate /, /boot, /var
and some number of other miscellaneous partitions that I usually
mount on /u1, /u2, /u3, etc. (Note there is no separate /usr
partition listed, though usually I do like a separate /usr
partition too. I also like a separate /usr/local.) I almost
always make /home a symlink to a directory on a /u* partition.
(I also like to have at least 2 swap partitions, each on a
different disk...)
If you have a backup system that is restricted in size, it is
very handy to limit partitions such as /home to some size that
allows the entire partition to fit on one tape.
Symlinks are handy when you discover, six months after you did
an install, that your 500Mb /usr partition just isn't large
enough. There is no need to re-partition the disk in order to
have more room to add new software. If the disk itself is too
small, just add another disk. But whether another disk is added
or whether all the extra space on the existing disk is in the
wrong partition makes little difference. The point is you can
use symlinks rather than go through the pain of re-partitioning
the disk.
