877 No boot file - but appears to have IOS

Hi All,

I have two 877's that have both reset with the following messages on boot, and dir of flash and lost+found

Any and all advice / help appreciated.  It appears that there is a IOS on the flash? but rommon doesn't know where it is.  I tried to "set" with no luck as set is read.

I have noticed that the IOS is 0 size.  Thoughts?

Much thanks.

877 No boot file - but appears to have IOS

Your IOS is corrupt.

The fastest way to push the IOS back into the router is via TFTPdnld.

Before you push the IOS, make sure you compare the MD5 hash value at the Cisco website.

Re:877 No boot file - but appears to have IOS

Use a recovery method tftpdnld or xodem to put image to the flash.


Before reloading the n/w deviced we need to verify the checksum.

Please let me know if u need any help
