I would be very grateful to receive some help concerning the next questions
on Linux slackware installation:
I have prepared the hard drive and have successfully installed Linux 3.1
slackware on it.
The Linux installation program was able to see CD-ROM during the
installation process (I have installed it from CD-ROM).
After finished with the installation, I set up the LILO program to start
either Windows 98 or Linux, depending on what I chose. Then I tried to go to
configuratoin section and set up my hardware. I gave the system all the
specifications of my mouse and CD-ROM, but after the rebooting - it would
not find nerither CD-ROM nor the mouse. It looks strange, because it saw the
CD-ROM during the installation.
What should I do to make the CD-ROM and mouse work properly!!!???
I configured the XF86Config file for the X Windows system, and after I type
startx and pres @Enter@ it gives the graphically lookoing interface with the
light blue screen background and the small window in the left upper corner
of the screeen. And nothing works then, even the mouse pointer doesn't move
at all!? But when I press ctrl+alt+backspace - it quits the this module!
What should I do to fix this stuff!!!???
THANK YOU IN ADVANCE!

System.map is a kernel thing, see:
/usr/src/linux/Documentation/oops-tracing.txt
Don't see where it enters into the picture of moving files.
Now lilo's 'map' needs to be updated when the kernel and
certain other files used by lilo are altered in any way.

Linux is the obvious choice for large ASIC projects, the major
simulators are all available for it as are CVS, Flexlm and Xemacs, what
more do you need? Also Linux integrates seamlessly with other UNIXs such
as Solaris so you can run your backend applications on large servers.
For documentation Framemaker runs natively on Linux, but if you feel the
need to punish yourself by using Word and Excel that can be done also by
using Win4Lin. The pluses for Linux is that it's real Unix on cheap iron
so it's the best choice for workstations. It's certainly better than
running Exceed on top of NT to log into a buch of Solaris systems.

My fault. I thought System.map was a sort of database where locations
were saved (from where till where the kernel is situated on the HD, f.i.
from block 15468 to block 54862). Therefor I assumed moving things
(which changes the block-locations) would've made the System.map-file
corrupt. After reading the oops-tracing.txt and the klogd-man-page, I
now know better.

Yes. Well, you made me a happy man (I now know a little more of Linux

If this drive was made after 1998, it's probably not using the ppa
module, but the imm one. The correct order is:
modprobe parport
modprobe parport_pc
modprobe lp
modprobe imm
modprobe scsi_mod
modprobe sd_mod

Lilo is the exception. It does keep track of absolute sectors. Rerun
lilo.
There are some details you need to pay attention to to make that work,
but it's not really very hard.
If you've booted from a rescue floppy/CD-ROM, you've mounted your hard
disk partitions in different places than they usually go. And you may
have put your new filesystems in different partitions on the new
disk. That means that you need to adjust the lilo.conf file to point
to the right location for the kernel, and that you need to tell lilo
where to find lilo.conf. This is also complicated if you've attached
your new disk as /dev/hdc, for example, but will change it to /dev/hda
once you've moved everything. It's simpler if you attach the new
drive where it will live, and move the old drive to a temporary
location.
I use a small /boot partition. Running from the rescue disk, there's
nothing to prevent me from mounting the new /boot as /boot. Other
partitions would be mounted in temporary locations for copying. So,
after copying the old filesystems to the new filesystems, I edit the
new /etc files that need to be changed. For example, I'll edit
/mnt/newroot/etc/fstab to reflect the partitions that the new
filesystems will live on. And I'll copy /mnt/newroot/etc/lilo.conf to
/etc/lilo.conf, and edit it if needed - probably not. Patch the
kernel with rdev, if needed. Run /sbin/lilo. It will find the blocks
used by the kernel on your /boot partition and write them to the MBR
on the first hard disk, assuming that's how you've configured lilo.
Another approach is to edit /etc/fstab (if needed), and boot from
floppy. Run lilo. If you used the same partitioning scheme, the same
floppy will work. If you've moved root or swap, you should use rdev
to patch the floppy, while running from the rescue disk. I'm talking
about a floppy with a copy of your normal kernel, created with "cp
/boot/vmlinuz /dev/fd0". I use a monolythic kernel, which keeps
things simple. If you use initrd, that may add additional steps.
If you understand how lilo works, this is not hard to do. It's harder
to describe than to do.
This also works for Windows 98 and NT partitions. Just edit the
boot.ini file if you've moved NT to a different partition.

Hi:
We are attempting to install Linux Redhat 6.2 on a Dell Web server. We have
installed the device driver from Dell, but there is not much documentation
that we could find to assist us in configuring the drivers.
We are having difficulty configuring the firmware to recognize the Dell Perc
2-Si Raid Controller (which actually is Adaptec). We would like to
configuring the RAID for mirroring (RAID 0). Has anyone succeeded? Are
there step by step instructions on the web or that could be sent by e-mail?
Please e-mail me a copy of any reply posts and I will forward them to the
people doing the install.
Thanks,

Try adding a line like this to your /etc/conf.modules:
options parport_pc io=0x378 irq=7
This asssumes you use a standard printer port configuration and makes
it use interrupts for better performance. Also, go into the bios setup
and make sure you have EPP+ECP enabled for that port for enhanced
features and performance.

Actually, the HPT370 chipset does NOT support RAID in linux. It will
recognize only single drives. It says it on High Point's page here:
http://www.highpoint-tech.com/370drivers.htm
scroll down to the bottom where it says "Note: At this time, the HPT370
Linux patch is compatible with single disk functions only. (Non-RAID)"
There's your answer. I patched my kernel and it recognizes drives on
the HPT370 chipset fine, but not arrays. And well... THIS SUCKS.
It says in the documentation that Gentus linux supports HPT370 RAID,
and I'm going to try this crap linux distro out when I get home today,
but I'm wondering.. If it *does* work, and Gentus can recognize the
array, doesn't Abit have to release the source code patch for this
under GPL licensing? Thanks,
John

Assuming you've got a USB port on the computer, your easiest solution
is to upgrade to the latest 2.4.0-test release kernel, which includes
USB support. You should then be able to mount the drive. Check
http://www.linux-usb.org for more information on compatibility with
specific devices, though. (The last I heard, Zip drives worked, at least
mostly, but it's conceivable there's a problem in the latest 2.4.0-test
release.)
Another option would be to patch a 2.2.x kernel with appropriate
2.3.x/2.4.x code. Again, http://www.linux-usb.org has information on
this. This approach will take more effort initially, but may create
fewer problems in terms of compatibility with the overall kernel with
the rest of the system. (2.4.x rearranges stuff in the /lib/modules
directory, for instance, which can cause problems.)

Hi all
I`m thinking about getting either an AIT or DLT multi-tape unit (ADIC?) for
our Linux server (RH6.2). Does anyone have these units running OK under RH?
I dont really mind that it would probably require a `manual press the

Any tips or experiences would be gratefully received. Many thanks in advance
