I have the Asus A7V8X Deluxe and it comes with dual lan ports. I beleive one is the nvidia and another is the 3COM. I ran the RPM that came with the CD it showed up once and eth0 failed to initalize. Then next time I looked the driver was gone. Has anyone had this problem before or can help me get my network working again? I am running RedHat 8.0

You need to make sure of what your drivers are first. Once you've determined the correct driver you'll need for your NIC (ethernet card) you need to make sure it's installed:

lsmod

If it's not, run

modprobe <drivername>

This should install the module/driver for you. Once that's done, make sure you've got all your ISP information handy (primary and secondary DNS IP addresses, domain server name, DHCP server name if needed, DHCP server IP address if needed). You won't need any DHCP info if you have a static IP. Then run:

netconfig

Answer the questions with the correct ISP information and you should be good to go. After you run your netconfig, I recommend a reboot (ifconfig eth0 up should work, but it didn't for me--neither did dhcpd). A reboot should set your dhcp daemon into action and have it request an IP from the DHCP server (assuming you have a dynamic IP and not a static). You should be online at this point. Hope this helps.

I have the A7V8X standard, the 10/100 is by Broadcom and uses a BCM4401 driver downloadable off the net (source, not rpm). I didn't have any RPMs supplied with my board when i got it, would have been nice. I also am running 8.0. I hope this is somewhat helpful, otherwise, if you still don't know who the NIC is by, crack open your case and check out the board for the chip.
