unable to find network card?

Rick Garland — Tue, 27 Jul 2004 13:15:06 GMT

Hi all:

Got a HP/Compaq d530 system, a P4 at 2800 Mz CPU.
I am loading RH 9.0 onto it. Have gone through the paces but the networking has me stumped.

The OS says that eth0 is a 3c501 ethernet - the system has an integrated NIC on the motherboard. I have IRQ5 and the MAC of 000D9D9AB350.

When the system starts it complains that it cannot find the eth0.

What gives? Do I need to pass boot parameters?

Help, please?

I do not own such best myself but see what this link has to say about it !

http://www.tldp.org/HOWTO/Ethernet-HOWTO-4.html#ss4.1

Having say's that I do find a

/drivers/net/3c501.o

so I suppose you could try a

modprobe 3c501 io=0x300 irq=10

to see what gives .

Dead NIC?

Load windows on it and see if the card works?

This sounds vanilla, it should work with RH-9.

Hi,

For certain 3com network cards, a wrong chipset may be detected.

Try "3c59x". In /etc/modules.conf, replace :

"alias eth0 3c501" by "alias eth0 3c59x"

Good luck.

Also note that there is a bug with RH9 on some compaq machines, where the network card is successfully detected upon installation, but won't start upon system boot.

The quick fix is to remove the network card entry from '/etc/sysconfig/hwconf' (which will look something similar to:

-
class: NETWORK
bus: PCI
detached: 0
device: eth
driver: eepro100
desc: "Intel Corp.|82801BD PRO/100 VM (LOM) Ethernet Controller"
vendorId: 8086
deviceId: 103b
subVendorId: 0e11
subDeviceId: 0012
pciType: 1

but have 3com information), and let kudzu re-detect it after a reboot.

Just a thought, something to try ;)

i'm inclined to belive your kernel has detected the wrong chipset.

most every 3com intergrated NIC in the last 4 years has been a 3c905 or 3c920 (basically a 3c905 card-on-chip).

try one of these drivers.

Many thanks all.

The RH9 detected the wrong card type. It is not a 3c501 as 1st stated, it is a BroadCom Giga card. Loaded with 3.0ES and all is well.

Again, thanks!
