Reply-To: [EMAIL PROTECTED]
This note explains a solution to a LILO problem with a SCSI-controller
Adaptec AHA2940AU.
Linux had been installed on a system with three SCSI disks, connected
via an AHA2940AU controller.
The Linux resided on the third disk (bios=0x82), an 18 GB disk, in an
extended partition, starting above the 8 GB limit.
Fortunately, although the (SCSI-)BIOS dated from 1996, the AHA2940AU
supports LBA adressing in its BIOS.
After installation LILO booted fine from the boot floppy.
But when booted from disk, nothing at all happened.
The diagnostic floppy that comes with LILO 21.6 got stuck in the middle
of displaying EDD parameters.
After some investigation it was discovered that the BIOS has a bug in
the Int 13h function 48h: Get Disk Parameters.
This function returns without error (CY=0), but the buffer isn't updated
(hence, all 0).
In consequence, the diagnostic floppy and LILO itself got confused.
The problem could be solved by explicitly specifying the disc geometry
in the LILO configuration.
The geometry data was retrieved by means of the partition table
information displayed from /sbin/fdisk.
This is the /etc/lilo.conf file that solved the problem:
disk=/dev/sdc
bios=0x82
sectors=63
heads=255
cylinders=2231
boot=/dev/sdc5
map=/boot/map
install=/boot/boot-text.b
message=/boot/message2
lba32
image=/boot/vmlinuz-2.2.16-22
label=linux
initrd=/boot/initrd-2.2.16-22.img
read-only
root=/dev/sdc7

You seem to resist defining what unsetting a password means.
You say you do not wish to run with no password. Running with no
password would be a dumb idea.
Another interpretation is that you want it disabled; i.e., unchanged,
but login impossible. You seem to say you do not want that either.
WHAT DO YOU WANT?

No special distro. I've found this on the LinuxFromScratch-Documentation
(http://www.linuxfromscratch.org) to build my own Linux. Therefor I'd
like to know the meaning of this entries.

AFAIK non-root user can't normally switch to runlevel (0|6) with
"shutdown", "halt" or "reboot", expect the combination of
"ctrl+alt+del" (if this is present in the inittab file) or any other
methods like 'sudo' for example.

Subject: Backup Windows 2000 partition from Linux
Reply-To: [EMAIL PROTECTED]
Date: Thu, 28 Dec 2000 16:12:50 GMT
I have a system that has Windows 2000 Server on one disk, and Linux on
another. I would like to backup the W2K partition from Linux, delete
it, and restore it later.
Is this possible?
The W2K disk looks like this, according to Linux fdisk:
Device Boot Start End Blocks Id System
/dev/sdc1 * 1 548 4401778+ 7 HPFS/NTFS
I am thinking of something like this:
# copy raw W2K partition to file
dd if=/dev/sdc1 of=/tmp/sdc1.dd
# copy MBR to file
dd if=/dev/sdc of=/tmp/mbr.dd bs=512 count=1
# backup both files to tape
cd /tmp
tar -cf /dev/st0 sdc1.dd mbr.dd
# (maybe put a 'z' in the tar args to compress it, to make it
# fit on a single tape)
To restore, I would ensure the disk is partitioned exactly the same,
and then reverse the above steps.
Would this work?
Would this enable me to perform a "bare metal" recovery of my W2K
system, assuming I recreate the partitions exactly as they are now?
I know so little about W2K...
Thanks.

You multi-posted this message -- posted it separately to different
newsgroups. I answered in another group. In the future, when you must
post to multiple groups, cross-post -- post once, listing all the groups
on one line. As a general rule, you should post to just one group, with
two or three as the absolute maximum. Multi-posting wastes time and
bandwidth. For instance, I wouldn't have answered if I'd seen Peter's
answer in this thread, which provides basically the same information I
did in my response.

This might indicate that the libraries you installed are not compatible
with the version of agetty which is installed on your machine. I suspect
your only solution is to put back the libraries in the version you had

My suggestion: Stick with the current standard: ext2 (2nd extended
filesystem.)
There is no reason to go after other obsolete formats on a new system.
There are enough complicatons without didling with the file system
format!

[ snip ]
Not me, in those situations I usually just go to the beginning of the
line <ESC>I, and type my first command, then a semi-colon. It saves
a few keystrokes. Or sometimes I just <ESC>dd, execute the first
command and then <ESC>p, to bring back the other one. I still cant
think of a time when interactive comments are necessary. The only
exception I can think of would be for instructive purposes, as in
a Usenet posting answering a newbies question, as in...
bash-2.03$ pwd # get the current working directory
/home/anm
or something similar. I do not use bash though, so I guess the point
is moot for me. I just dont see why interactive comments need to be
enabled by default.

You can post the results to this thread if you want.
64 MB is not very much, if you're using a memory hock like

With 64 MB you should use 128 MB swap, but it won't help you much, try

Hello,
as someone else pointed out, use ext2, it's AFAIK one of the fastes file
systems in this world.
Only if you have big HDs/RAIDs > 100-200 GB, and don't have the time for a long

a rare hard reboot, you should look for reiserfs, which is journalized...:-)
