I have a desktop with two hard drives. It used to have a copy of
Windows on each drive. I decided to replace the second one with Fedora
Core 6.

I have never used Linux, but was a VAX/Unix user many moons ago. My
partner is a long-time Linux user. He has figured out most of the
problems so far, but is now stumped.

I bought the O'Reilly "Fedora Linux" and downloaded Core 6. Below is
what I've done so far. What should I do next?

1. Installed per book. No boot.
2. Made grub floppy & booted from it.
3. Installed grub into MBR of 1st disk; now can boot either system.
4. Tried ping; can't reach router.
5. Rebooted Windows; ping works fine; all network ops work fine.
6. Rebooted Fedora; still can't ping.
7. Turned off DHCP, manually set IP; still can't ping.
8. Turned off SELinux & Firewall; still can't ping.
9. Patched /etc/hosts, so ping -c 1 localhost works; still cant ping.

Here are the results of various tools:

ping 192.168.1.1 -> "Destination Host Unreachable"

ethtool eth0 -> "No data available"

arp -a -> "(192.168.1.1) at <incomplete> on eth0"

ifconfig ->
