Try just setting it with the command:

confreg 0x2102

then reset

If not do you see any errors during the boot sequence?

Hope this helps.

Re: 2600 router bot able to boot normaly

If you enter it in ROMMON mode you don't need to save it if you enter it in ENABLE mode you do.

Can you boot the IOS using the BOOT command from ROMMON mode?

Re: 2600 router bot able to boot normaly

Can you manually boot the IOS code from the ROMMON prompt? If so, just add a line to the IOS config with the path of the image. For help, do boot ?

Re: 2600 router bot able to boot normaly

As the guys above have mentioned...enter the following at the rommon prompt.

rommon 2 > boot flash:c2600-js56i-mz.121-3.T.bin

Cheers
