Subject: LILO with rh7.1 & win2000
Date: Sat, 26 May 2001 09:42:42 +0200
I've just installed succesfully my rh7.1 but i've some problems with lilo.
When i finish the installation of rh my lilo can't see win2000 so i entered
in linux and i typed lilo -u /dev/hda, now with my old mbr i can see win2000
but there's no notice of linux, the only way to login is to use the boot
dosk. And so i did, in order to reinstall the lilo, but another time my lilo
can't see win2000
My lilo.conf is:
boot="/dev/hda"
map=/boot/map
install=/boot/boot.b
prompt
timeout="50"
message=/boot/message
linear
default linux
image="/boot/wmlinuz-2.4.2-2"
label="linux"
read-only
root="/dev/hda5"
Is there anuone who could help a fresh linux man?
Thank's
Maury

This is not necessarily true - I have a 5610 modem (id 12b9:1008), and
all setserial tricks don't work with kernel 2.2 serial driver. This driver
simply does not support (some) PCI serial ports. In order for the modem to
work with kernel 2.2 you need to download the driver from
http://serial.sourcforge.net. 2.4 includes the new driver.

I've seen the same problem and solved it by adding the following to my
lilo.conf (assumed that your Win2000 is on /dev/hda1):
other=/dev/hda1
label=Windows2000
That worked.

Use the command, chpasswd.
ex)
# useradd foo

|Yes, you are using the useradd -p parameter I suspect. Useradd expects an

If you write the script in Perl (and probably Python) there is a crypt function
just for this purpose. You will need to look up the manual for it, and read the
description of 'salt' and how it works.

If your system is not going to accept routing broadcasts from remote routers
and hence there is no need for your own routing table to be updated, you can
ignore these broadcasts. It only becomes an issue if you are running a
routing daemon locally and require updates.

Yep, you could just drop it silently and not have your /var/log/messages file
fill up. This will have no impact on your system, as your system is already
denying the packets as it stands now.

You need ghostscript and something like apsfilter. Have a look at the Linux
Printing HowTo. As always, I don't remember the URL where you can find it
(there are many!) but you can just open up a search engine and search for
"Linux Printing Howto". That shoule do it.

As a final tip to add to the others, sometimes it is nice to both view and
save the output of a program. The little utility 'tee' is handy for this.
You can use it like this:
gcc -o testprog test.c 2>&1 | tee out.log
The 'tee' program will save what it receives on standard input to the named
file, as well as printing it to the screen. This often gives you the best
of both worlds with regard to viewing and saving of errors.

hi folks
is there anyway to get E16 to start apps once it boots - i'm thinking of
starting gkrellm for example - without hacking the xinitrc files etc, ie
in the same way E can automatically start up Epplets that were started
in the previous session
thanks for any advice

Asked HP before ?
That's manufacturer's task. If HP can't help you, return the device.

Swap? You should never be using swap. It works at the speed of the
disk, which is maybe 100 times slower than memory.

It is too large.

Not if they are on the same disk/controller.

NO (how could it? All accesses go through the same physical device).

You could have none, near as anything, if you plan on any kind of speed
optimization!

Don't do this. You have it arse-backwards. Swap is not a concern.
Memory and disk are. Optimize those, not the thing you use when they
fail!

In my honest opinion the best way to start applications on X startup IS
editing .xinitrc, at least for me epplets sometimes start in completely
wrong places, there might extra epplets that I didn't want etc. But
anyway, you can make any appliction start on E startup with the
'Remember' setting.
Alt-Click on the application's titlebar, select 'Remember...' and on the
dialog click 'Restart application on login'.

Hi,
I've just started trying to install Redhat 7 on an old P1 90Mhz, I
have a similar problem. I need to use a boot disk to start the installation
as my cd-rom does not boot. In the setup when it asks whether the data is
on a SCSI cd or Other. I do not have the device driver and have been looking
all night for one. The cd-rom is a Creative Quad Speed, running off the IDE
channel of a Vibra16 sound card. I have tried it off the secondary IDE
channel on the motherboard with the same results.
Any help or direction would be greatly appreciated as i am about to go and
spend money on a new box if this doesn't work out soon.
Thankyou,
Matthew Ritchie

You might need to make some changes in /dev per the info in
/usr/src/linux/Documentation/Changes. I too had trouble getting
ppp to work under 2.4-series kernels, turned out I had missed a
vital step in the process, went back and followed the instructions
in Changes regarding PPP, it came up like a charm.

This relates to the above, I had a similar error message. I
double-checked
the kernel config, I did in fact have PPP support compiled in, so I was
really at a loss. The changes I mentioned above cleared the problem up.
Hope this helps.

If _all_ you did was delete a partition or alter the partition table in
some way you can recover your data by simply recreating the partition with
Linux fdisk. Messing with the partition table does not touch the data in
the partition.
