I have to install a bunch of servers, and for various reasons will be
using Redhat. I see how to install using a kickstart file, but how do I
create the kickstart file? There are references to a utility which takes
the current installation and creates the ks.cfg file based on the
current install. Obviously there is such a thing, but I sure don't see
the name of it.
I have several 600+ page Redhat books, but they all want to tell me how
to use a ks.cfg, not how to create one in some way better than by hand.

I remember there was a serious problem with a CMD640 controller due to
the fact that (as far as I remember) there was only one memory buffer
for both IDE channels, causing data corruption when both channels were
working, for instance installing from a CDROM to a HD.
I remember that after this was discovered workaround code was added in
the operating systems to prevent both channels working at the same
time.
There was at the time (three? years ago) a lot of discussion on the
internet and also testing programs so you could find out if you had
such a chip. Try searching for CMD640 and error or flaw or something
like that as search terms.

Are you using the mixer to unmute & set volumes on the various channels?
Alsa starts with everything muted & volumes at zero normally.
There's nothing special about compiling alsa under 2.4.0 (assuming you're
using the latest alsa version). If you're asking about where to put the
modules, I put them in /lib/modules/2.4.0/kernel/drivers/sound.

Does Linux support double mmap calls where a 2nd mmap() can be used
to overlay an existing memory map to another address? I tired of
following all the calls through from sys_mmap() to see if it does
or not (got pretty deep, but nothing obvious one way or the other).

Did you install the modules with "make modules_install"?
Also, you _did_ upgrade modutils, didn't you?

Hi..
I am studying linux device driver.
now I am looking through mouce device driver, "busmouse.c".
However, I could not understand "MODULE_PARM(mouse_irq, "i");
I searched the parts of linux kernel source. but, the source is very
complicated. I want to know the function of the sentence.
Thanks in advance.

There are some problems with ppp-2.4.0 and the 2.4.0 kernel with
getting options from /etc/ppp/options.ttySx files. Try ppp-2.4.0b3
if you use an options.ttySx. Or use ppp-2.3.11 which seems to work
with the 2.4.0 kernel despite the 2.4.0 minimum requirement given in
Documentation/Changes.
Following the Linux mini ASDL howto, which seems to be a good place to
learn something about ADSL, ANT = ADSL Network Termination.
If you have a ANT that connects to a NIC on the linux box then it should
be easy (really easy to *say* that since I've no ADSL experience, BTW).
If you have a ANT that connects to a USB connector on your box then you
may be out of luck. But there are drivers for some USB "modem" support
in the 2.4.0 kernel source, and there is support for using a standard
serial card with a USB connection (for using PPP?).
If you have a PCI integrated ANT/NIC card then there is not likely to
be a Linux driver for it.
Good luck, and thanks for qualifying "yank"; aren't all U.S. citizens
called "yanks" by all aussies? :)

Subject: how can i modify kernel memory at runtime
Date: Fri, 19 Jan 2001 03:26:47 GMT
Hi:
I want to try to modify an instruction in
kernel memory. Is there a utility around that
can do this easily.
All I need to do is deposit a single 32bit
value at a particular kernel location. I've
determined the location I want to change
by using gdb:
gdb /usr/src/linux/vmlinux /proc/kcore
(gdb) x/x get_unmapped_area+15+8
0x8011bef3 <get_unmapped_area+23>: 0x40000000
I want to be able to change this value without
the need to rebuild the kernel. (I believe this
value will change where in memory libraries get
loaded)
I'm not worried about syncing with the kernel, but
if such a utility would handle that too, all the
better.
thanks
eric

Thanks for kindness answer.
and... but...
my problem is not only "running X", but also "Writing device support
program". T.T
I must write device support program such as device driver or library.
but, unfourtunly, I am first time linux developer, I can't decide the
methode of development.
that is real problem.
Please answer which right to me.

There used to be an mkkickstart utility (and package), at least I'v
found one on a 6.1 and a 6.2 CD, but not on the 7.0 CD. It was a shell
script which generated the kickstart file for you. When I did my RHCE
with 6.0, there were some bugs in it (among others, partition sizes and
mouse directive were incorrect). I've never used it, so I can't give any
further details.

The directive is used to define a module parameter (hence the name)
"mouse_irq" which is a single integer. You can the load the driver using
e.g.
"insmod busmouse.o mouse_irq=3D12"

Hello,
I tried to insmod this small module to kernel
but got error:
hello.o: kernel-module version mismatch
hello.o was compiled for kernel version 2.2.18
while this kernel is version 2.4.0
I have kernel 2.4.0, and I have compiled this
program on 2.4.0 too.
If you look in file linux/version.h you will see:
#define UTS_RELEASE "2.2.18"
Maybe here is a problem, but I am not sure
Why does it happen?
