IOS upgrade

I have successfully upgraded the IOS on a 2621 from 12.1 to 12.2 .

However when I performed a reload on the router, I find it enters the rommom mode. I have subsequently performed a confreg and undergone the steps to change the config register value to 0x2142. .....through tthe following steps....

Yes.... to change the system configuration

Yes.......to Ignore System Config Info

However when I reload, I find that it goes back into rommon mode.

I have attempted to reinstate the original IOS image from tftp, after performing the set statements for IP_address, mask, gateway, tftp server, tftp file name.

But when I attempt a tftp copy of IOS, it comes back with an error stating that the interface was not initialized.

Thank you in advance for any words of wisdom.

Regards
