Help--Overwritten IOS

[Nutz]

One of the guys I work with made a slight error last night. Here is what he posted on Cramsession CCNA board:

<< I have a slight problem with my office's 3640. During tftp training, I had an individual copy the startup-config file to flash overwriting the IOS file. Now I'm stuck in ROMmon and when I do a dir flash: it shows the startup-config in flash.. I have another copy of the IOS file on a PC(it's a 10M file), but when I try to xmodem it to flash it says it is too large (8M Flash). I successfully downloaded the file with the xmodem -cr option, but when it uncompressed it errored on memory again. I'm working with 40M of DRAM. The router was working fine up to this point, so I'm confident I don't have bad memory. Currently, I do not have access to a PCMCIA card with the IOS (still working on that) to try booting from the PCMCIA. I've searched cisco.com repeatedly and haven't found an exact solution. I was wanting to try the tftpdnld, but it's not an option from my ROMmon prompt.

Since this router is currently set aside for desktop training, nobody is out of service. Any inputs, ideas, solutions would be greatly appreciated. Thanks

Personally, I think he's screwed until he can get into a CCO account and redownload the particular IOS for that router.

either that or call cisco, something ain't right.

Maybe wrong version or image for that particular hardware? Erase flash and try to xmodem the image again?

Have you packed the flash, to purge any old junk?

I think we got it licked. Thanks for the help. Here is what he had to say,

<< I finally talked with the individual (Nutz, I got a hold of Rico) who maintains the software aspect and it does appear I have the wrong IOS for this particular router. It wasn't stored where we normally maintain our software kits, so I grabbed the wrong one. It is a 3640 IOS, but not for the router setup I'm using (as you pointed out and your first link clearly states). I'll get it from him on Monday and hopefully the xmodem transfer will fix the problem.

Thanks for your input.......
