Cisco router keeps de-compressing and does not save

[Bobns]

The router would first only boot onto rommon mode. This has been solved with these steps:

1. Shut the router down.
2. Remove the compact flash from the back of the router.
3. Turn the router back on.
4. When you see the Rommon1> prompt, enter the command of confreg 0x2142.
5. Insert the compact flash.
6. Type reset.
7. When prompted to enter the initial configuration, type no and press enter.

After this the router wil load normally but doesn't save anything when I use the commando's copy run start etc. It is an CISCO 1841 Router this is what happens when I boot it:

Personally I think it is because of this. But I don't know how to fix it:

Hi

 This is the expected behavior.  After touter  come up, you need to change the config register again.

the value 0x2142 ignores the NVRAM memory.

You need to use the 0x2102

Router# configure terminal

Router(config)# config-register 0x2102

This was the solution. Thank you very much!
