No, you just need to load the driver for your NIC.

What do lspci and lsmod report?

[gentoo-user] eth0 does not exist

[Kenneth Hopping]

I'm installing linux-2.6.16-gentoo-r7.

Network initialization fails during startup:

 * Starting eth0
 *   Loading networking modules for eth0
 *     modules: iptunnel ifconfig dhcpcd apipa
 *       ifconfig provides interface
 *       dhcpcd provides dhcp
 *   Bringing up eth0
 *     dhcp
 *       eth0 does not exist
 *     Trying fallback configuration
 *     192.168.0.4
 *     eth0 does not exist

The problem appears to be that /sys/class/net/eth0 does not exist.
This is a pseudo-filesystem like proc that I cannot manipulate.

Is there some configuration file that needs initialization or a package 
that I need to install?

The documentation states: "DHCP is used by default and does not require 
any further configuration."

This is my first attempt with gentoo and kernel compilation so I'm not 
very knowledgable about modules. I just followed the steps in the x86 
installation handbook. Except for the network, everything else (cdrom, 
floppy) seems to work.

Ok, when you go to configure your kernel, go under "Device
Drivers->Network device support->Ethernet (10 or 100Mbit)".  Select
the option "3COM cards", and then the "3c590/3c900 series..." with an
'M'.

Assuming that you already configured and installed a kernel, so that
/usr/src/linux matches your running kernel, you should be able to just
do "make && make modules_install" to get the new driver.  You can then
try loading it with "modprobe 3c59x".  If you get no errors from that
command, then you should get connected automatically within a few
seconds.  If all goes well, it should work fine even after a reboot.
If you get errors, well you may have some more work to do to configure
and install a new kernel.

I've been somewhat terse about the steps required, assuming you have
some basic knowledge of how to configure and install a new kernel.
The gentoo handbook can help here, but if you still have questions or
something doesn't make sense, feel free to ask for some more help.

Maybe he already have the driver compiled as a module but its not
loading it?! Just a guess, try:

modprobe 3c59x

And take a look at the last lines of "dmesg" output.

If that was the case it would have shown up when he ran:

# find /lib/modules/2.6.16-gentoo-r7/kernel -type f -iname '*.ko'

Look in his previous mail. It didn't. This of course assumes that his running 
kernel is 2.6.16-gentoo-r7. To the OP. Run

# uname -r

to verify that.

And you can add another piece of self-taught knowledge to your
toolkit :)  This is one that I do without thinking now.

*shrug*

Probably all you had to do after enabling the module in the config was:

# make && make modules_install && make install

You would need to make sure that /boot was mounted during the 'make install' 
(which probably was the only step you missed) and then it would have worked. 
You almost *never* need to reinstall from scratch..

Thanks for pointing me in the right direction. I finally got eth0 
working, but it was a struggle.

I selected the 3COM options like you suggested and recompiled the 
kernel. Unfortunately, during reboot I got "invalid compressed format 
(err=1)". I tried "make clean" to flush everything and compiled again 
but it still wouldn't boot. My drastic solution was to reinstall gentoo 
from scratch. Now the network initializes properly during startup. I 
also learned to always keep the last working kernel as a backup when you 
reconfigure.

Glad you got it working.

Hmm, do you use lilo or grub for your boot loader?  'Cause I think
this is only possible when using lilo, if you forget to re-run lilo
after installing the new kernel.
