NIC not detected....

Hi,

We were salvaging some old hardware lying around and I though of utilizing a HP Vectra PC (PIII 800 Mhz, 64 MB, 20 GB HDD, etc.) as a router. So when I got another salvaged NIC (this one is a Realtek make and utilizes the ne2k-pci driver when connected to other PCs.) and put it in the comp. Nothing happened....

I trid lspci and nothing showed up regd this card. (the onboard 3com was detected tho.) I thought the NIC was blown. But when I look around at the back, the green light was on. Also when I connected the NIC to a switch, both the link light on the NIC and the Switch light up. What is going on??? I tried changing slots. Also sometimes when the NIC is plugged in and I restart the Linux BOX the PC wont boot and would all sorts of noises (I mean loud noises from the speaker on the MBoard.) But if i powered it down and cold booted, it would start up but still no NIC detected.... any ideas???

Over to you folks....

Hi,

   You might want to check the vendor and model of your NIC card. And search the internet (vendor's website) for the Linux driver.
Download and compile it (The README or INSTALL file which come with driver will tell you how to install the driver for linux).
However, you cann't find the driver or find there is no linux support for your NIC. Then you can post to the newgroup to ask some
driver programmer to write one for you.

    You need to have driver for the NIC to let Linux recognize it.

Hi,

As I had mentioned.... similar NIC cards are working in linux....just this card, it is not getting detected. It uses the ne2k-pci driver.

Cheers,

Are the NIC cards identical? If not, then it might not work. You need to have the "right" driver.
Do that NIC work on Windows ME or 98SE?

Hi,

The NICS are the same....my point is.

Is it possible that the NIC is switching on (as inferred by the leds on the NIC card and on the connected SWITCH.) but is not being detected by the OS?

Just tell me a possible cause and the points are yours?

If the card is the same, according to you, then it should be detected at boot-up.
Try to do
# dmesg | grep eth
to see eth0 and eth1 (2 NICs)
And check closely in dmesg message (# dmesg > /tmp/dmesg.txt) around "eth"
For Intel Pro chip, you will see "e100" or "e1000" (gigabit), and for 3Com chip "3c9XXX", Broadcom chip "bcm5XXX" or "tg3".
Make sure what's your NIC chip and do
# lsmod
to check the module loaded or not.
Sometimes you need to modify /etc/modules.conf and make alias to make it work. However, this instruction come with
the Vendor's driver package.

Hi...

My cards exact make is " RealTek RTL8029" and it uses the  ne2k-pci driver. It even shows up when doing a lsmod. Please lets try and get around this confusion:

When i execute lspci it shows:

01:09.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8029(AS)

so it is getting dectected. According to http://www.scyld.com/ne2k_pci.html, the ne2k-pci driver supports the NIC. what could be the problem due to which the card is getting detected when we perform a lspci but all attemts to load drivers fail.

Cheers,

Karan
