Actually, I'm using Scientific Linux 4.2, which came on 4 CDs. It is

_very_ stable: haven't managed to modify it at all. But I have already
found some bugs in it (in particular, system-config-display doesn't work
correctly, and the supplied video drivers are very flaky -- details if

video drivers have nothing to do with the kernel. Those are under X.
What is system-config-display?

It records the parameters relating to keyboard, mouse, video adapter and
monitor.

you want them) that I've managed to get around. To say that I'm not en-
amoured with this distro would be a major understatement. The Scientific
Linux managers at Fermilab say my earlier problems were in parts of the
distro they hadn't touched. I had sent a description of the problems and
solutions to RedHat, and never got any response back.

You would hardly expect RedHat to do something about a rewritten version.
Might as well send Redhat problems with Mandrake, since Mandrake branched
off from Redhat 5 years ago.

But according to the people at Fermilab responsible for SL, that part has
_not_ been rewritten. My description sent to them was intended as helpful
feedback.

It does not matter. RedHat is NOT going to help debug someone else's
distribution. One the Fermilab people released a new distro, they took it
all over. It is now up to them to correct everything. They can of course
check to see if it really is also a fault in Redhat and then submit a bug
to Redhat, but Redhat is not going to help support SELinux.

Yes, at this point that's what I think will have to be done.

Why?

I don't know what else to do, everything else having failed.

? I am sorry, but that makes no sense. Why don't you take a soldering iron
to your motherboard instead? It would make as much sense.
You recompile your kernel only if you have narrowed down the error to the
kernel and the recomilation is the ONLY way to fix it. You do not say "I
give up, lets try recompiling the kernel."

One more, unrelated, question: I have an external USR 33.6 modem that
works fine from OS/2, but linux can't seem to find it. From what I've

Find it? What is to find. It is connected to a serial port. You just
send stuff to that serial port.

Oh. Thanks for the reference.

read, my (faint) impression is that modem support is already available
as a module. I've looked on the I'net for a linux driver for it, but
could not find anything. Any thoughts?

?? an external modem does NOT need a module.

Good, now I know.

Yes. One of the reasons I was a snippy as I was is that there is a severe
disjuncture between your wanting to recompile the kernel and your state of
knowledge about serial ports. The latter is a fairly basic item of a Linux
system, and your lack of knowledge there makes me suspect that you are way
out of your depth in trying to recompile the kernel.

It would be far better for you to tell us what your problems are in detail.

Or maybe use a more standard distro where the people might be more willing
to give help. I use Mandriva. In a University physics setting.

Here's another head-scratcher I ran into: I have an IDE DVD/CD recorder,
which Linux sees and mounts/unmounts jst fine. I also have a SCSI CD-ROM
that I have no idea how to get recognized. Linux sees the SCSI adapter
okay, but how do I find the CD drive attached to it?

/dev/scd0 probably.

I'll try that; thanks.

NOte that scsi devices typically start with s. st is tape, scd is cds, etc.
