I surely appreciate the feedback, I wish it was the EEPROM...
here's the results of ifconfig

-bash-2.05b# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:D0:69:41:09:53
          inet addr:10.0.110.39  Bcast:10.0.110.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2084 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1448 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:39

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

looks good...

Here's the results of running route:

-bash-2.05b# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref   
Use Iface
smi-ssd         *               255.255.255.0   U     0      0       
0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
default         10.0.110.1      0.0.0.0         UG    0      0       
0 eth0

which looks good... inetd is running just fine and dandy...and the
eth0 bootp is static.

Problem occurs when I try to ping the gateway... I also notice that
the led on the switch is off... like the ethernet device never came up...

Wondering about power supply I read somewhere in the linux rags that
the reason why the ethernet driver could fail is power intermittence?
If that was true, how can I diagnose the board to make sure all the
devices/peripherals are running at their optimal level?

Hmmm... I don't want to just RMA this board due to a bad NIC, I just
bought this board 3 months ago...the MTBF should be years not months?

Any help is appreciated.
