Ray, information follows in its respective section.  Thank you again for all 
your insight, and effort!  In addition to the questions/recommendations you 
made, I have some questions.  These questions immediately below are AFTER I 
typed in your directions and listed the results in the respective section.
1)Why do I have to type ifconfig -a to list eth0?  If I don't use -a, then 
only the loopback comes up.
2)Again, when eth0 comes up with -a, then no IP or Broadcast addresses 
appear without typing /sbin/dhcpcd eth0.
3)After typing /sbin/dhcpcd eth0, then eth0 appears with an IP and Bcast 
address WITHOUT typing -a?

*******************************************

4)By going into my Network Configuration Window after typing neat at the 
prompt, I selected to activate device when computer starts.  When I 
rebooted, as root:
a)the address for root is: root at dhcp-304-32 root.  This is different than 
before when it was root at localhost.  Also, is it correct that I now don't 
have to type -a to /sbin/dhcpcd eth0 to load eth0 because its detecting it 
at start?  Not only that, but the IP and Bcast come up without typing 
/sbin/dhcpcd eth0.
b)typing netstat -r brings up three IP addresses, but still no Gateway 
except for default
c)ide-cd and cdrom now don't appear when I run /sbin/lsmod.  All the other 
modules appear.
d)my box is much slower
5)Why do I have different IP addresses when I run netstat -r and 
/sbin/incofig?  Netstat lists the IP as 66.91.112.0, and incofig lists the 
IP as 66.91.114.64?
6)Now when I run cat /etc/resolv.conf, 5 results are listed:
nameserver 24.25.227.34
nameserver 24.25.227.36
nameserver 24.25.227.32
domain hawaii.rr.com
search hawaii.rr.com
7)I still don't have internet acceess.  Would you please include a few IP 
addresses that you know work.

Again, result to your directions follow in their respective sections.

Okay, typed that in.

Here's the million dollar question: why is it that when I don't type 
/sbin/dhcpcd eth0, I don't receive an IP address?  eth0 does appear, but no 
inet addr.  Is it because I'm starting dhcpcd on my ethernet card by typing 
that?  After I type /sbin/dhcpcd eth0 I get the same IP address as yesterday 
(IP for my box correct?).

Unfortunately, I didn't get internet access.  Typing www.hotmail.com brought 
the same error message: Unknown Host
