Very Computer

Classic case of "but it worked before..."

NE2000 Compatible 10M Ethernet card on a Pentium 133 running RedHat 5.1 and
no problems.  I upgrade to RedHat 6.1 and the Ethernet card is not detected
during the install.  I use Kernel Configurator to define the device in
/etc/modules.conf as following:

        alias eth0 ne
        options ne io=0x300 irq=10

and everything starts to work fine.  Again, no problems.

This past weekend, I upgrade to RedHat 7.1 and again the Ethernet card is
not discovered so again I modify the /etc/modules.conf file (as I did above)
but things still aren't working now.

During the boot up, "Bringing Up Interface ETH0   [OK]" flashes by.  
Examining dmesg gives me:

NE*000 ethercard probe at 0x300:  00 40 05 3c 24 b5
eth0: NE2000 found at 0x300, using IRQ 10.

So I assume the card is initialized, booted, working, etc....

When I try to ping another machine on my home net, I get:

"Destination Host Unreachable"

I have verified all IP address/mask pairs and they ARE correct.  I have
checked cables and even the hub by swapping and they are NOT the problem.  
netstat -rn returns exactly what I would expect as my routing table.  
Sniffer captures show the RedHat 7.1 box arping for the IP address it is
supposed to be pinging (which I would expect), but the arp is never
resolved, accoring to arp -a.

The only other message I'm seeing that may help is in dmesg after an
unsuccessful ping:

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Tx timed out, lost interrupt? TSR=0x1, ISR=0x3, t=107.

I don't know what that means.  Any insight as to what this problem might be
and how to fix it???

        cheers.

This past weekend I also did an install of 7.1.  Aftwards which I found out
that there was no sufficient default route.

Check yours if you haven't allready.

Well this is the * bit. I don't know exactly but check for things like
PnP OS in the BIOS or PNP enable options on the NIC, also check for any
conflict of IRQ, this is an ISA card make sure the BIOS thinks irq 10 is ISA
