Cisco router issue

[pdw8]

I've started building my cisco lab but get the same issue on two 2620 routers that came from different sources. The built in ethernet and the WIC's I installed do not show up in IOS. Its onlt when I do a reload I see an error related to the ethernet port.

cisco 2600 (MPC860) processor (revision 0x200) with 53248K/12288K bytes of memory.
Processor board ID JAD05041C6L (2823619291)
M860 processor: part number 0, mask 49
Bridging software.
X.25 software, Version 3.0.0.
32K bytes of non-volatile configuration memory.
16384K bytes of processor board System flash (Read/Write)

00:00:04: %LINK-4-NOMAC: A random default MAC address of 0000.0c84.02db has
been chosen. Ensure that this address is unique, or specify MAC
addresses for commands (such as 'novell routing') that allow the
use of this address as a default.

Anyone got any idea how I fix this?
Thanks,

1) You in configure mode when trying to get at interface Ethernet 0/0? The error on the first command you try points to the fact that it doesn't know the command "interface" which might indicate you're not in configure mode. What's the symbol of the prompt (> or #)? What version IOS? There's a message that would indicate that there's a config file already there, but from a different IOS version.

2) Certain WICs are only compatible with processors of a certain model or newer. I had this problem with a router I bought an ethernet WIC for - the router processor was too old. Worth checking. The fact that you can't see the built-in ethernet would indicate this isn't the problem. (1) is most likely.

None of the interfaces show up in any mode, you should see the built in ethernet but not even in show version. The strange this is I am 99% sure the ethernet interfaces were good when I first got them. All I have done since is upgrade the memory fom 32/8 to 64/16.

The only common thing is the MAC error. Is that causing it?

This is usually caused by an IOS issue. Are you sure the IOS you are using is definitely for your model of 2600?

I've not swapped the IOS yet as I need the ethernet port to TFTP to its IP address.
Is there anyway of upgrading the IOS over the console port only?

Yes. xmodem mode aka ROMmon.

BTW.

Are your in configuration mode?

ADSL-R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ADSL-R1(config)#int eth
ADSL-R1(config)#int ethernet 0/0
ADSL-R1(config-if)
