Copying IOS from DRAM to flash -- ROM Mode

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

system crashed - writing core on router logs

Hi Manju,

Thanks for reply.

I saw this error when Router  was up and running..

After sometime i lost access to router.

then i console in to router and it was in ROM Mode.

I tried reset command few times.But no luck.

Then i rebooted the router but still it was in ROM  mode.

After doing reset command few times it loaded the IOS.

Here is info from

system crashed - writing core on router logs

Hi Mahesh,

For this issue.  Have a look at this doc to make sure everything in your router is setup correctly.  If not, I recommend downloading an IOS version without any security features and see if you still get the same error messages.

Hi Reza,

So far routers looks ok.

I downloaded this IOS    c2600-adventerprisek9-mz.123-26.bin   -  as it supports MPLS.

Is this IOS  version  ok -- means no bugs,without security features?

Thanks

mahesh

Mahesh,

Ok, glad you have good version to work with.  With IOS images, it is hard to tell, but as long as it is working don't touch it. Remember,  2600 series is pretty old, and may not support all the features you need, but they defiantly provide all the good basics.

Where is the IOS when you do a "dir flash"?

I don't see it in your output.

do i need to connect router int fa0/0  with straigh through cable to laptop?

You need a cross over cable to connect your PC/laptop to the router directly.

If you try it with a cross over cable and it still does not work, you need to use Xmodem to load the IOS

Copying IOS from DRAM to flash -- ROM Mode

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

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
