Well, if IP-Config is not complete, we can change the configuration
using 'ifconfig' after the kernel starts. I did that. And I noticed that
'eth0' can receive packets but cannot transmit any packets. Here is the
result of running ifconfig.

---------------------------once----------------------------------
#ifconfig
eth0      Link encap:Ethernet  HWaddr 00:06:17:01:02:00
           inet addr:192.168.5.24  Bcast:192.168.5.255  Mask:255.255.255.0
