Maybe something was not copied that is needed??? like the other stage
and device.map files.
 

The boot sector is just the first cylinder(sector zero of cylinder zero)
of the floppy diskette, hard drive or CD/DVD disc. If not used for the
boot information (MBR) then it can and is used for data, in otherwords
it's all data.

Try the following instead to make a ext2 GRUB boot floppy as root by;

# fdformat /dev/fd0H1440

# mke2fs /dev/fd0

Note; You can use a blank formatted DOS floppy instead by skipping the
two steps above. You will lose the added security (accidentally
deleting a file for example) of the ext2 filesystem using this floppy .

# mount -t ext2 /dev/fd0 /mnt/floppy

# grub-install --root-directory=/mnt/floppy /dev/fd0

# cp /boot/grub/grub.conf /mnt/floppy/boot/grub/grub.conf

# umount /mnt/floppy

When you update the kernel all you need to do is mount the floppy and
copy the updated /boot/grub/grub.conf to the floppy. Or you can edit
the /mnt/floppy/boot/grub/grub.conf by hand (for a custom multiple
system boot floppy for example) if you want.

SMP startup problem

Posted: 26 Jul 2005 12:29 PM PDT

FWIW: I am having similar issues with my dual P2 running FC3. For me,
it seems to go through most of the boot process, but right before it
displays the login screen (if running X startup; else just the login
prompt), the system freezes. At that point I can only do a hard reset,
and try again. It usually takes 3 to 6 tries before it will
successfully complete the boot, and then all runs well. In the kernel
log I get the error:

WARNING: Kernel Errors Present
vesafb: probe of vesafb0 failed with error -6...: 3 Time(s)

This problem does not occur if I run the single CPU kernel.

As for hardware (CPU/motherboard) issues: this system ran several
years with MS Windows 2000, and then RH9 for a couple more years after
that with no problems. So, according to my deductive reasoning,
something changed in FC3 that causes this.

I haven't tried FC4 yet, since that seems to have broken other things,
and I don't feel comfortable with upgrading my main server just yet. I
would be very interested if anyone has any real information about this
problem though.

Just my dual cents worth.

How can I get into the GUI of Red Hat Linux 9 ??

Thank you for your suggestions.

HOwever, do not do so as root. Make sure that you have at least one 

Q1. Would you please tell me how can I define that ordinary user? any
special command? I'm assuming if I go to level5 from level3 it will do
it automatically..am I thinking right? please correct me if I'm wrong.


If you want to do root stuff you can always open a terminal and do 

Q2. I really like the idea of defining an ordinary user and keeping the
root untouched. but as you said to do root stuff I can always go into
the terminal and in your word "install" password. Do I really literally
have to "install" or set any password? or it's done automatically? I'm
little confused here. What I'm trying to say here is...Would I get the
prompt for password? If i do..don't I have to set the password before i
get that prompt? How would I set that? or it's the same password you
are talking about which I already set during the installation process?

Sounds like they need a new support team then. Let me know where that
shop is and I'll find a replacement service team that can do a better
job.

There was a time when Windows needed to be rebooted every six months or
so but reformatting and reinstalling is just dumb these days. It really
screws the uptime statistics. It's possible that their users keep
getting the machines infected with malware, and reformatting and
reinstalling will fix that. But that's mainly a management problem not
really a technical one. Malware, even on Windows, is mostly preventable
if you have the users trained and the support people are on the ball.

Windows server systems can pretty easily deliver 99.99% uptime and with
care they can deliver another .009% too. Seven nines reliability out of
the box is the next target for Windows and Linux/BSD.
 

Five years ago I was running a handful of NT4 servers. The only
unscheduled downtime in five years was when the UPS battery failed. It's
a pity that Windows still needs to reboot when some of the patches are
installed, that's pretty much the only downtime my servers had.

It's horses for courses. I run both Windows and Linux. Linux has now
reached the point I predicted a few years back, it's possible to build
and run a Linux system with almost no specialist knowledge. I run SuSE
and Ubuntu boxes, both excellent systems. I also run Windows.

boot knoppix from hda10

What do you mean by "boot from"? You can install knoppix on disk easily
enough!
 

I don't know what you are on about. Knoppix runs off (for its root) a
special compressed file that pretends to be a (compressed) block device
with a file system on it. It has its own driver in the knoppix kernel.
All you need to do is put that file on disk, put the knoppix kernel on
disk, add the knppix kernel to your boot loader, and change its bt
parameters to point at your hard disk and the file image on disk instead
of at the cdrom and its file image.

Besides .. knoppix comes with an install utility to put itself on disk
with!

Ye ghods, I hate these auto-mounting widgets. Nautilus is also not your
friend, but pulling it out tends to violate dependencies, so I wind up
renaming the binary to set it aside without yanking the RPM's.

No, that was primarily a LILO interacting with the BIOS limitation. Grub
seems to be quite free of the problem.

Thank you!. Now that's useful, I'll look at it ASAP.
 

You apparently knew the right keywords, my searches gave hundreds and
hundreds of irrelevant hits.
 

Thank you for pointing it out. You've also missed the point that not
everyone here is already running Linux or running from their Linux box.
(This is especially true for those of us who use a Windows games box at home
and admin Linux at work, or vice versa.) And the patch is more obscure (or
at least was for me) than seemed apparent to you.

Why make life tough for the newbies with the "begin" format of replies,
especially your cutesy use of it with the virus.txt.scr line?

And Peter once again leaves out the good bits. What is an environment
variable? Why, it's one that gets preserved! What is a local variable? It's
one that gets reset! Isn't that helpful?

Starting up a new shell re-runs certain shell configuration files, which may
in fact reset some of them automatically. Which files these are depends on
which shell you are using, they're different for bash and csh, for example.
If you're using "sh" or "bash", which are the same shell under the hood in
Linux, run "info bash" and look at the parts about .profile and .bashrc for
more information.
