Nadeem, I know when you tftp a file into flash in rommon mode it erases it. I said that in the previous message. I don't have a problem right now, but RIK said "Try to boot to rommon mode and format the flash." I just want to find out what command he is talking about to format the flash from ROMMON mode. And what routers and switches he is talking about for future reference and trouble shooting.

If this does not work, you might wanna format your flash by inserting it in another router slot and load image from there. Then insert it back and boot from flash by changing the conf-reg, simple!
