Cisco 2821 will not boot from flash

[calkins.t]

I have a 2821 that will not boot from any CF.  I have confirmed that the CF are in good working order by using them in another 2821.  The bootup looks like this...

System Bootstrap, Version 12.3(8r)T7, RELEASE SOFTWARE (fc1)

I have even formated a new CF and copied an IOS to it.  That did not work either.

Hi,

Did you try using the fsck command if it exists from rommon mode? I have the same problem on a C2950 and it was solved after that file system check.

Hi,

Can you do a one time boot of your IOS from a USB memory device and then try formatting the card in-situ?

USB-boot support starts with bootstrap version 12.4(13r)T6.

Apologies, I missed that bit.
