why flash read only" error message

prasanthpk · ‎02-12-2002

why my router always boots from rom rather than from flash.config reg is correct but once we try to access flash as "sh version" or "try to copy flash contents" shows it is a read only.the same error is received when i try to load IOS from a tftp server

pls give me a solution

i am confused to get " flash read only" error message

and my router always boots from rom instead of flash

Your problem description is a bit confusing. When your router always boots in rommon, how did you do

a show ver or try copy tftp flash?

What type of router is it anyway?

I had the same problem where I had to replace the flash.

the other option might be

partition flash 2 4 4

and load a real skinny ios on it.

Your idea is better

So its the ancient IGS box. To me, looks like you have to upgrade the bootroms to make your flash

read-write both. In some cases, it could be a bad flash too.
