Hi,

I recently tried upgrading from R5C7 to R5E50, and I can't get a network connection (manifested by an inability to run DHCP and no connection to DataDirect). I believe it's to do with the IRQ settings, but I can't wrap my head around this, being a rookie. Here's some specific info:

1) If I reinstall R5C7, I get a network connection--so, the card/cable/router is physically fine. One of the changes between R5C7 and R5E50 is some how preventing a network connection.

2) After a regular automatic install of R5E50, at boot after install (before set up), I get this message at the very top of the screen:
> ACPI: BIOS age (2001) fails cutoff (2002), acpi=force is required to enable ACPI
> Suspend 2 2.2.8.4: Missing or invalid storage location (resume2= parameter). Please correct and rerun lilo (for equivalent) before suspending
> INIT: version 2.86 bootlog
> Starting the hotplug events dispatcher: udevd.
> Synthesizing the initial hotplug events...done.
> Waiting for dev/ to be fully populated...IRQ 11: nobody cared (try booting with the "irqpoll" option)
> handlers
> [<d0f86410> (usb_hcd_irq+0X0/0X60 [usbcore])
> Disabling IRQ #11
> done.

When I get to the "Use DHCP broadcast?" question and answer YES, the computer stalls at:
> Sending DHCP broadcast from device eth0
After about 20 seconds, I get this:
> Sending DHCP broadcast from device eth0Opoeration failed.
> Failed.
> Hit return to exit.

So, no network connection there.

3) If I disable Serial Port B in BIOS, the "IRQ 11: nobody cared" message goes away. Instead, when I answer 'yes" to the "Use DHCP broadcast?" question I get the following message:
> Sending DHCP broadcast from device eth0
> Message from syslog@mythtv at Fri Apr 13 08:21:10 2007 ...
> mythtv kernel: Disabling IRQ #11
> Operation failed.
> Failed.
> Hit return to exit.

Again, no network connection.

4) My hardware setup:

Mobo: Intel Desktop Board D845PT
NIC: integrated on desktop board
PVR-350.

I'm stumped. Any advice is most welcome.

The irqpoll reference is a suggestion to put it in your boot up.
I think R5E50 uses lilo.
You're after something like this:

It's worth while reading up on both lilo and grub anyway, so do that first.
Some kernel revisions handle IRQ/BIOS stuff differently from others, so your problem doesn't surprise me.
