When the flash memory is upgraded using the MEM870-4F= flash memory upgrade kit the router goes to rommon mode after reboot, and the router does not recognize the IOS that is in the existing flash on the router.

Could not open boot directory: flash:/

Unable to open boot file

dir flash: shows no files

is this normal? Do i have to tftpdnld an ios after upgrading the flash memory on an 871?

I have this problem too.

Yes, I do believe you will have to TFTP a new IOS onto the router. Since you can dir flash: and not get any errors, it sounds like your flash is just wiped out. The same happened to me when I upgraded an 871.
