Hi, 

I am wondering if some one out there can give me some help. I have problems
with the Ethernet card after I upgrade kernel from 2.2.14-5.0 to 2.2.19  for
RedHat-6.2.  My Ethernet card is 3Com 3C905B. 

1). if I boot to kernel-2.2.14-5.0, using ifconfig, I can see the eth0, lo.
Using netcfg, I can see eth0 is active. the networking works fine. However,
 
2). if I boot to rtlinux, I noticed that eth0 failed initialisation during
boot, and using ifconfig, I could not see eth0, using netcfg, I can see eth0
is inactive.

I also checked /lib/modules/2.2.19-rtl/net, there is only a dummy.o.
Following are what I did for the upgrade ( the instruction given by FSM
Labs).  During the make config, I used most the default setting, but
answered Yes to all Ethernet cards.

Did I get something missed out or wrong?   Furthermore, I want to use SSH,
or openSH, Can I use RedHat-7.0 ( upgrade kernel to 2.2.19) for RTLinux-3.1?
since RedHat-7.0 includes openSH.

Many thanks in advance.

I downloaded linux-2.2.19.tar.gz, rtlinux-3.1.tar.gz, then followed the
instruction

 cd /usr/src
 tar xzvf linux-2.2.19.tar.gz
 cd linux
 cd /usr/src
 tar xzvf rtlinux-3.1.tar.gz

4. Create a symbolic link from within the rtlinux directory to the linux
directory:
 cd /usr/src/rtlinux
 ln -sf /usr/src/linux ./linux

5. Patch the kernel with the RTLinux patch:
 cd /usr/src/linux
 patch -p1 < /usr/src/rtlinux/kernel_patch-2.2.19

6. Now, clean all old .o files and stale dependencies:
 make mrproper

7. Now, configure the Linux kernel:
 cd /usr/src/linux
 make config

8. After you are finished configuring the Linux kernel, type:
 make dep

Steps 9 through 11 are x86-specific.

9. Compile the Linux kernel and modules:
 make bzImage
 make modules

Install the Linux modules:
 make modules install
 cp arch/i386/boot/bzImage /boot/rtzImage

10. Configure LILO. To do so, edit /etc/lilo.conf to contain the following
piece (you only need to do this once):
image=/boot/rtzImage
label=rtlinux
read-only
root=/dev/hda1


11. Install LILO. To doso, type:
 /sbin/lilo

Restart the computer:
 /sbin/shutdown -r now
Load the RTLinux kernel: At the LILO: prompt, press "Shift" or
"Tab". This will give you a listing of the available kernels. Enter:
 rtlinux
RTLinux should boot.
