should i try to copy ios from TFTP to Router so that it can store in FLASH?

Also config reg shows

Configuration register is 0x3922

yes, see if you can load the IOS to the flash.  Then change the config register to 0x2102  and reboot

Mahesh,

Here is the problem.  Your flash is 16Mb and the IOS you are trying to load is 17Mb, so it will not fit into your flash.  you need an IOS that is smaller the 16Mb.

here is what you have

I do not know if its impolite to butt in, but maybe you could try the squeeze command now.

Software Configuration GuideFor Cisco 2600 Series Routers

squeeze {flash: | slot0:

in your case squeeze flash:

Good luck.

Hi,

i do not know if i reboot the router then if it will come back or not?

Hi Reza,

Issue is fixed.

c2600-adventerprisek9-mz.123-26.bin 

This IOS  was bad ---  as it was showing very less Flash and DRAM  on my Router.

Also this IOS  -- while using xmodem with c option was not working at all.

I tried many times but no luck.

Then from ROM mode i used Xmodem and copy this IOS

c2600-advipservicesk9-mz.123-26.bin.

Now all is good
