NIC IRQ Conflict?


I've got an old Compaq Presario 5000 computer with a Network Everywhere NC100v2 network PCI card. When I first installed it, it didn't work. I tried a different PCI slot, and it worked. Then it stopped working. Moved it to a different slot and it worked for a little while. Now its not working anymore.

From the googling I've done, it sounds like an IRQ conflict. I'm not sure how to fix this. I took out the modem so It's the only PCI card, but no luck. On boot it says "eth0 error". Sometimes it will boot up, but not connect and then freeze. In the BIOS I can switch the IRQ between 3, 5, and 11, but whatever else has the same IRQ also switches.

Im running a dual-boot with Xubuntu and Windows ME since its an old computer. It has worked in both of these at some point in the past. Thanks for any help.

Replace the Ethernet interface, I just got one of these crapping pieces of junk working on a Wndows 2000 system (for my landlord). Had to manually install the drivers and inf files then force (manually editing the registry) to use the interface.

Your time and sanity is worth far more then the cost to replace the interface. SMC, Netgear and Linksys PCI Ethernet interfaces can be purchased for less then $20.00 (more like $10.00 to $15.00) for most anywhere in the USA.

LOL. I figured it was probably a problem with a cheap card. I'm a little hesitant to get a new one though since the computer itself probably isn't worth much more than $20-30. I'll keep my eyes open for a sale but in the meantime if anyone has any other helpful tips I'd appreciate it.

Show the output from the typed command (just the Ethernet interface portion please);

/sbin/lspci -v

0000:01:0a.0 Ethernet controller: Linksys NC100 Network Everywhere Fast Ethernet 10/100 (rev 11)
Subsystem: Linksys: Unknown device 0570
Flags: bus master, medium devsel, latency 0, IRQ 11
I/O ports at 1400 [size=256]
Memory at 10000000 (32-bit, non-prefetchable) [size=1K]
Expansion ROM at 10100000 [disabled] [size=128K]
Capabilities: [c0] Power Management version 2

I moved it to PCI slot 3. In the BIOS there i made it the only thing with IRQ=11. To do this I moved Onboard VGA to IRQ 3 from IRQ 11. The onboard USB also has IRQ 3, but this does not seem to cause me any problems. I was only able to give it its own IRQ in slot 3.

The system boots, but I can't access the network. network-admin shows the default gateway device as eth1, but it used to be eth0.

Apparently its got a 100% approval rating in the HCL: http://www.linuxquestions.org/hcl/sh...uct=52&cat=144

After reading you HCL link, it seems that the Ethernet uses the tulip module, so is it loaded???

cat /proc/modules | grep tulip

If no then try loading it; modprobe tulip

If yes then try configuring it; ifconfig eth1 xxx.xxx.xxx.xxx (some IP address on your network)

Yes, tulip is loaded. As I said it has worked before in both linux and Windoze. I will try ifconfig eth1 and see if that does anything.

I tried
Code:
$sudo ifconfig eth1 192.168.x.x
Nothing appears to have changed.

I also couble checked and tulip is definitely running:
Code:
$cat /proc/modules | grep tulip
tulip 51744 0 - Live 0xc4a10000
