"Here in America" I don't have to deal with /the customer/, but mostly
with other team-mates, co-workers etc. That's about 90% of my
correspondence. Interaction with /the customer/ takes little
correspondence for me. When I do, I am curteous:
Instead of simply refusing an attachment or shooting a short email
saying "try again in something x-platform compatible", I'll explain in
great detail why it's not a good idea to assume everybody's using
MS-Word version $WhatIHaveInstalled, I'll explain the alternatives, how
to use them, where to get them and the like.
I also point out that while I /can/ get the content of the document,
it's an inconvenience for me.
So far I have encountered only one instance when the person did not
understand my point and has from then on at least made a point of trying
to send something I can read. In that one instance I respectfully point
out that I do not like this, but if that's the way he wants it, that's
the way it's gonna be.
I've experienced that blind adherence to "the customer is always right"
usually leads to more work for me - while if I point them in the right
direction, often their reaction was "Oh, we didn't know that. Thanks
for letting us know - we are kind of new to the internet and just
assumed everybody has Windows/Word." The first time I got this reaction
(and actually all future correspondence in text) I was very amazed to
find out that "the customer can actually see that he's wrong".

Treating intelligent people like they're dumb is disrespectful. It's a
matter of how you communicate the message: yelling "You dumb asshole,
shove this MS-Word Doc up your ass" will certainly not work. Being
polite and willing to help, will.

Hi,
I compiled linux kernel 2.4.1 on my machine which has IDE dirve and made
it run. Now I compiled the same kernel on another machine with SCSI drive
but it doesn't work. It is using initrd to boot the old kernel 2.2.41
using initrd while in the first case above it doesn't boot using initrd.
Please help me out.

My mistake -- the name of the program is CloneCD. Its prime us appears
to be 'backing up' copy protected CDs, mainly games.

It's never wrong, it can be different from what LILO thinks.
That can be the reason of such confusion.

I'd expect problems with LILO on hda indeed.
You can tell that the CHS values are different.
try booting with hda=58168,16,63
I'm not sure, LILO may complain again.
fdisk most certainly will, but give it a try.

This is not the same as in dmesg.
This is strange. Appearantly not a problem though.

This image is the one on hda too, right?
If you boot from hdc, this is probably erroneous too.

Will not work for me unless I go to a lot of trouble, because the ppp
ports are not up when I boot my system, and that is where the trouble
is expected. I suppose I could monkey around in the ppp* scripts, but
they came from RedHat, and nearly incomprehensible.
So I just setup stuff for ipchains instead.

OTOH, the system might come with /usr/bin/perl, but the admin installed
another perl anyway, because either he doesn't have the same compiler,
wants or needs difference configuration options, or wants or needs
a different (newer?) version of perl, while (s)he cannot remove or
symlink /usr/bin/perl because utilities coming with the OS depend on
the particular version.
Then /usr/bin/env only works for those who have the correct path.

First off, this is a Linux problem, not a UNIX Programming problem. Newsgroups
have been trimmed to Linux-specific ones only.
Now, here are the questions that have been asked:
1. Do you have enough system resources, like IRQ's?
5 cards is a lot for one system, but if that's all the system has in it
there should be no conflicts.
2. Does the card work if you install it in place of a working card?
Normal hardware troubleshooting procedures apply here. Check for conflicts.
Is there any way you can use virtual IPs to consolidate the addresses into
fewer cards?
