How Linux loads modules and a problem with my integrated network device

unclestoner · 11-12-2007, 04:35 PM

I am running Fedora 7 (2.6.21) on a Dell Optiplex 755, which has an Intel 82566DM-2 integrated network device. I believe the e1000 driver is supposed to work for this. But, upon booting I have no eth0. For now I've installed another network card which works fine, but I'd like to troubleshoot the Gigabyte card.

Firstly, can someone explain to me how/when Linux decides to load modules? Does it match up the devices PCI identity (for instance) to a particular module that can drive the device? I know you can use modprobe/insmod to manually load modules in the kernel but I'd also like to understand how the kernel decides what to load when it boots up or at other times.

Secondly, if someone could help me troubleshoot the problem with my Intel 82566DM-2 integrated network device that would be great. lspci can see the device (output below), but there is no eth0 when I do an ifconfig. However I noticed when I booted up with the other (working) NIC, it was assigned eth1 so the non-working network device is occupying eth0 somehow. I tried manually loading the e1000 module with modprobe and it didn't complain, but I still have no eth0. When I used the "system-config-network" GUI, I added manually specified the an "Intel EtherExpress/1000 gigabit" device, but when I tried to Activate it I got the message: "e1000 device does not seem to be present, delaying initialization"

Thanks,
Dave

I am running CentOS as a terminal server on a basic Fujitsu Siemens Primergy Econel 100 Server. This system comes with an integrated Intel Ethernet Controller. I have a Realtek Gigabit NIC running, but for this setup to run correctly, I need a second NIC, and am hoping to use the integrated one. Having great difficulty getting CentOS to see the integrated card. here is the output of

How would I go about enabling this, or getting system-config-network to recognise it as a valid ethernet card?

BTW, I'm somewhere between a NooB and an intermediate user, so be gentle!

Thanks for your time.

Hi Lenard,

I am a newbie to linux and was breaking my head with this Intel ether express gigabit NIC. Thank god I got the apt answer in your reply to the above query.Thank you soo much.
Would you mind sending me the step by step like how to build and kernel-devel kernel-headers. it will be of great help to me . for me some of the things you mentioned are really tough , but I want to learn how make it work i am sorry if ask for very silly configuration.

Thanks for helping me.
Praveen.

Hi Praveen,

I posted to this thread a couple of months ago, and got this working. Can you give us details of your machine, make, model, etc., and what version of linux you are running? It would be most helpful. Also, if you can copy and paste the result of

# lspci -v

run as root, that would help. Hopefully, I may be able to help!

irishbitte.

Hi irishbitte,

Thanks a ton for helping me.

I have dell optiplex 755 with the Intel(R) 82566DM-2 gigabit Ethernet connection, i have downloaded drivers for the same with you guys help. Now want the steps how to make it to work in redhat 3.0. Later on i might have to install 4.0 and 5.0. basically working on a testing environment.

irishbitte , iam so sorry i donot know how to paste the output of #lspci -v onto this site .

Please help me.

Thanks to you & all in advance.

irishbitte · 06-10-2008, 12:03 PM

Hi Praveen,

Sorry for not getting back to you, how did you fare out?

The way to post the output from lspci is as follows:

Code:

dave@dave$: su
password:

root@dave#: lspci -v

After this, select the output with your mouse, and use the EDIT menu at the top of the shell. I'm presuming you are opening a shell inside X windows.

praveenjayak · 06-11-2008, 03:48 PM

Hi Sir,

Good that i have completed that task.
Thanks ALOT for all your help....

Talk to you again ...

Thanks
