Dear Hughes,
Thank you for your reply!
As you metioned I installed device driver when I installed
RHEL 4.0 U1 by typing "linux dd" and inserting device driver CD
according to X4100's installation manual.
I just intalled RHES 4.0 U1, not updated anything.
So the running kernel version is kernel-smp-2.6.9-11.EL as shown below.
[root at atlas ~]# uname -a
Linux atlas 2.6.9-11.ELsmp #1 SMP Fri May 20 18:25:30 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
Thanks a lot!
Sungsoo Kim

This means that you installed a driver when you installed the OS ... do
you still have the RHEL kernel what shipped with update 1 .. or have you
upgraded the kernel since then.
Have you done any other updates (besides the kernel) since update 1?
What is the output of this command:
uname -a

More important than anything else is figuring out what kernel you need
to use. There is a forzen CentOS-4.1 tree at http://vault.centos.org
that has all the 4.1 kernels.
(In CentOS ... 4.0 is the original release, 4.1 is update 1, 4.2 is
update 2, etc.)
After the kernel issues are defined, a plan for doing a switch can be
put together. Is there a driver source so that you can build a new
driver for new kernels (if required)?
