Newbie - Won't Detect PCI Ethernet Card

[ti83programmer]

I have an HP Pavilion 4450 (few years old), Celeron 366MHz, 192MB RAM.

I try booting and one of the first lines says "PCI: cannot allocate resource region 4 of 00:07.1".

Everything works fine after this (I have display problems, so I type "knoppix xmodule=vesa" at the boot prompt and it's fine), except the ethernet card isn't detected (and I assume the above error is related).

I try installing it, but it won't take. I'm not sure what to do from this point. Suggestions?

A quick google search (http://www.google.com/linux?hl=en&lr=&ie=ISO-8859-1&q=PCI%3A%20cannot%20allocate%20resource%20region%2 04%20of%2000%3A07.1&btnG=Google+Search) reveals you should try pci=noacpi or acpi=off. I find a cut and paste of any error into google will usually come up with a few revelant pages to help with solving the problem.

How can I type both this and the vesa thing in at the same time? Is there some kind of console I can type that into once Knoppix has already started? Or can I put them both on the same line? I'm sorry, I'm a complete and total idiot when it comes to Linux.

Nevermind, I used this:

knoppix xmodule=vesa acpi=off

I also tried pci=noacpi and neither worked.

Did you still get the error? Also what does the output of lspci -v in a console tell you is the card detected there. Try dmesg | less to see the boot messages one screen at a time to see if the card is detected at boot or if there is an error. What is the card model number, manufacturer? Also try pci=biosirq. Check in your bios to see if it is set for Plug'N'Play OS if so turn it off.

If you have an on-board graphics chip/integrated motherboard maybe try:

knoppix pci=biosirq xmodule=vesa

What kind of graphics chip does your computer have?

rock

knoppix xmodule=vesa acpi=off

I also tried pci=noacpi and neither worked.
It should read knoppix xmodule=vesa noacpi...

I try booting and one of the first lines says "PCI: cannot allocate resource region 4 of 00:07.1".

So why can't it allocate that memory? I smell IRQ conflict. Do this in a term:

procinfo -f

That will tell you what is using what IRQ. As will

lspci -v

And let's not forget

dmesg

In your BIOS did you disable IRQ sharing? PCI BUS mastering? Automatic assignment of IRQ's?

Of course I don't know what options your BIOS has so I can't say for sure but you should hopefully see some options as I have posted above.

You could always try removing the card and booting to see if you still get the same error. Also moving the card to another slot might help.

I have the same comp and the same problem.After running lspci -v, this is what I get.

You have an IRQ conflict somewhere follow rickenbacherus's advice and see what that tells you. I have the same type of card in my machine it uses the tulip module so you may want to try lsmod in a console to see if the module loaded after you sort out the IRQ there will be a 1 in the line for it if it is in use. My settings for reference:




00:0a.0 Ethernet controller: Linksys Network Everywhere Fast Ethernet 10/100 model NC100 (rev 11)
Subsystem: Unex Technology Corp.: Unknown device d020
Flags: bus master, medium devsel, latency 64, IRQ 10
I/O ports at c800 [size=256]
Memory at dffffc00 (32-bit, non-prefetchable) [size=1K]
Expansion ROM at dffc0000 [disabled] [size=128K]

As you can see mine gets a IRQ and as a result has a I/O port which yours doesn't.
