Yeah, sounds OK. You could try using a configuation profile
so it doesn't bring up eth0 in the first place. ifdown eth0
should work too.

Date: Wed, 28 Jun 2000 20:48:54 GMT
This brings up the whole FONT issue with linux and the X server. X does
not support TrueType fonts natively (not the one that comes with redhat
6.2). Redhat 6.2 comes with a truetype font server, called xfs, which
renders the truetype fonts for X programs.
X is picking huge fonts to give to the dropdown list boxes and it ends
up making the whole thing look stupid.
It would help to give additional fonts to xfs, the font server. If you
have a windows machine you can copy windows' default fonts from, that
would help.
There is a how-to available called "Font deuglification". Last time I
looked at the linux documentation project's how-to list, it was not
included, so you may have to search for it. It will have instructions
on how to add some fonts to the font server, and your display will
render more-correctly, although still not perfectly. Netscape 4.72 its
self doesn't handle fonts very will IMO.
You can also tinker with the new Netscape 6. Go to www.netscape.com and
pick downloads from their "other downloads directory", and grab
netscape6. My first impressions are that it will render the fonts more
friendly-like.

Buy more RAM? Seriously, if a program malloc()s 256M and you only have
192M, you're going to hit the swap partition no matter what you do unless
you buy more RAM. WTF are you running, anyway, that requires 450M? Not
even Netscape+VMWare+Oracle Lite requires that much.

If you want to boot Linux from your hard drive, you pretty much
have to use lilo. But that is not really what your problem is.
You don't want to put the lilo boot loader in the MBR because
that gives NT indigestion.
The standard way to set up a dual boot Linux+NT system is
described in the Linux+NT-loader (mini) HOWTO, which should
be available as part of any Linux distribution. It can also
be found at the Linux Documentation Project web page.
That method uses the NT loader as the primary boot loader and
by an artifice lets it find the lilo boot loader as a secondary
loader for the purpose of booting Linux from the hard disk.
See the HOWTO for details.
There is another way to set up a Linux+NT system which uses
lilo but does not change the MBR. The point is to put the
lilo boot loader in some other partition, not in the MBR,
and then using the Linux fdisk make that the active partition
on the disk. (This assumes you have one disk. This method
won't work if you can't put lilo somewhere on the first disk
if you have more than one disk.) With some effort all this
can be done during installation, but it is easier to boot
Linux from the boot floppy made during the installation
and take care of the details afterwards.
Here is an example of what the partitioning might look like
for a system with one IDE hard drive.
/dev/hda1 NT
/dev/hda2* Linux primary partition marked active
/dev/hda3 Extended partition
/dev/hda5 Linux logical partition
/dev/hda6 Linux logical partition
/dev/hda7 Linux swap partition
And /etc/lilo.conf would look like
boot=/dev/hda2 #This would normally be /dev/hda for the MBR
.
.
.
.
image=/boot/vmlinuz...
label=linux
.
.
.
other=/dev/hda1
label=nt
table=/dev/hda
The dots represent other usual lilo.conf entries.
You can't normally put the lilo boot loader in a logical
partition such as /dev/hda5, but you could put it in the
extended partition containing it, in this case /dev/hda3.
Where the dots represent normal lilo.conf entries

Subject: kernel 2.2.16 questions
Date: Wed, 28 Jun 2000 21:04:03 GMT
I have a quick question about rebuilding my kernel to the latest stable
(currently 2.2.16).
I noticed quite a few changes in the menu options. I also noticed that
many common options are not even defaulted as modules. such as network
devices like PPP, generic sound support, etc. All of these are modules
that came with my redhat 6.2 distro.
Is this normal, and should I go through every option to decide if the
device I want should be a module or built-in? I'm a bit new at the
kernel-building :-).
And I noticed that when I pass vga=ask to the kernel via lilo, it
ignores that option unlike the 2.2.14 kernel that comes with RH 6.2. Is
there any way to get the smaller text mode?

I don't really know what your problem is, but I would bet it is
a hardware problem.
If you bought your machine from VALinux, you might consult them,
even if it is past warranty. In the past I've found them
reasonably helpful.

Hi all,
The following program is valid for MSDOS6.2 or older.
C:\>debug
-a
0AD7:0100 movax,201
0AD7:0103 movbx,7c00
0AD7:0106 movcx,1
0AD7:0109 movdx,80
0AD7:010C int13
0AD7:010E int3
0AD7:010F
-g
-d7c00 7dff
You can see the Master Boot Record now.
-d7dbe 7dfd
You can see the partition table (4 entries) now.
-f7dbe 7dfd 0
Clear the partition table.
-a
0AD7:010F movax,301
0AD7:0112
-g=100
Write the MBR back to hard disk.
You should have deleted all partitions in this hard disk, and you can
repartition it now.
I have used this simple technique to remove NT & Win2000 partitions for
times.
If you have enabled the anti virus function in BIOS, the computer will
show a small box to warn you when you try to write back the MBR.
As I know, BIOS load MBR to 0:7c00, then jumt to this address. Magic
begins from this point.
-u100
You can see the MBR code, or a MBR virus code maybe. :)
It usually move itself to other place, then load the activated
partition's boot sector to 0:7c00.

What I would do, go into your old kernel, make menuconfig.
>From there, go to the bottom, save out your kernel config as
a file somewhere accessible to all kernels like /usr/src/
Now go into the new kernel tree, make menuconfig, and read
in this kernel config file. Done. I'm sure someone else will
have a better simpler faster way.

Try using some propietry windows c++ builder thingy. I used one once for
exactly that purpse, and it was very easy. Visual C++ or Borland C++ builder
will allow you to drag and drop network stuff. Using borland c++ will
definately be problematic for windows programming.

cdrecord has a packet writing mode?
See http://sourceforge.net/project/?group_id=7091, but I'm pretty sure
packet writing is only supported in late 2.3 and 2.4-test kernels.

I suggest you use both of them for a while and then make a choice
about which one suits your needs and taste best.
KDE is more businesslike, cornery and robust-looking, and the
soon-to-be-released KDE2 includes a complete MS-Office-like set of
packages and a very advanced web-browser. KDE is the GUI to be used in
business-environments. Because of the businesslike look KDE shares
some resemblance to Windows and Apple GUI's.
Gnome, on the other hand, is more playful and softer to look at, with
as few as possible sharp edges and lines. It keeps a little more true
to the original Unix-GUI standards. Gnome is more friendly towards
casual home users. Gnome is also much more faithful to the
GPL-standards (all open source) and therefore often preferred by the
more experienced Linux-users.
I'm talking about the standard Windowmanagers that come with these
GUI-systems, of course. Windowmanagers can always be replaced by more
appropriate ones as necessary.

That should be "post-intall" and "pre-install" to force an insmod to wait
until another required module is first installed. See "man modules.conf".
