Cisco 801 changing IOS

Hi all,

Does anyone know of any issue's with replacing the ios on one of these routers while in boot#

I have followed

but the router appears to rename the file c800-y6-mw.122-13a.bin to c800-y6-mw when it copies it. I thought it might be the full stop but I get the same results if I rename the file to c800-y6-mw-122-13a-bin

Any idea's?

thanks for your time.

Re: Cisco 801 changing IOS

Here's a way round it assuming your flash is empty save for TinyRom

Follow the steps you have taken to now.

Once the tftp is complete type save file

Then set file-name=c800-y6-mw

save again and boot.

This should get you up into IOS.

From here delete flash:c800-y6-mw, check you have [ ] around file in sh flash

squeeze flash

copy tftp flash using the correct filename ie c800-y6-mw.122-13a.bin

Once that is there reboot and break into boot#, type erase, set file-name=c800-y6-mw.122-13a.bin and save again.

Powercycle and all should be OK!

Re: Cisco 801 changing IOS


thanks for the reply. I can't delete the c800-y6-mw file if its running it.

however - It seems I didn't read the paper properly and I missed the = sign for saving the file after its copied - it now works!

thanks for getting me there.

does anyone know why the tftp shows the "wrong" name though? is it by design?
