Russell, and Mark:
Here's what I get:
If I do a netinstall and select "Desktop", everything seemed to work
out of the box. However, I really didn't want that much software
installed, so I tried installing "minimal".
I then get:
Runlevel is N 3
Network Status reveals three configured devices, and active are "lo eth0"
ifcfg-eth0 is as you describe
Performing "service network start" and "chkconfig network on" and a
reboot did not solve the problem. eth0 had an ipv6 address, but no
inet addr, which means it's not going to work in my home network.
I then added to the file /etc/sysctl.conf
the line: net.ipv6.conf.all.disable_ipv6 = 1
Still no IP address, and when I issued "service network restart" I get:
failed: no link present. Check cable?
HOWEVER, pulling the ethernet cable and re-inserting it, then issuing
"service network restart" got a valid address. After a reboot,
again it didn't work. However, after waiting a while, I tried
"network start", got some messages about a file existing, and got an
