Updating cisco ios 2600
We note in passing that it would be extremely unwise to use an IOS image that was not created and supported by Cisco.
The router will do several tests while loading a new IOS image to ensure that the process goes smoothly.
M860 processor: part number 0, mask 49Bridging software. Basic Rate ISDN software, Version 1.1.2 Ethernet/IEEE 802.3 interface(s)1 ISDN Basic Rate interface(s)32K bytes of non-volatile configuration memory.
(Read/Write)Configuration register is 0x2102Like Burt said, if you have enough FLASH and the IOS image is small, you could have 2 or more IOS's in FLASH and then tell the router which to boot to such as in a dual boot computer You can do a "show flash" to see what you do have in FLASH and how much memory is available.
Usually the imagename will have a "k9" somewhere in the name . Worst case is I spend a few $$$ and bump up the memory so the IOS will load.
Until you get this no ssh config commands will work . I'll have to figure out how to boot from a TFTP server and load the original IOS again. Sniffer2112, For DRAM and FLASH that works with Cisco routers - check was at a Cisco convention several years ago and all the CCIE's kept talking about getting stuff for their labs at Anthony Panda I checked it out when I got home and have bought from him several times, in fact bought enough FLASH and DRAM to upgrade 20 routers at work and all worked GREAT. " and look at the menu, you need to set To load an IOS onto a router using ROMmon mode via Ethernet cable: Start the TFTP server Connect to the router via Ethernet cable (an Ethernet cable is preferred due to the large size of the file and the maximum speed that data can travel over the console cable)Before the IOS is loaded it is important to make sure that your router has enough memory to support the IOS.
WARNING: all existing data in all partitions on flash will be lost! y/n: [n]: y Enter y, and the IOS will load Once loaded you must boot up the new IOS by issuing the boot command -------------------------------------------Hope this helps!

T10Make sure Ethernet cable is in E0/0 and is in same hub/switch that the TFTP server is in, if you are connecting directly to TFTP you will need a cross-over cable. All was going well when I realized that the Fast Ethernet port was not configured. I've been flipping off the switch but should you do something at the command line to prepare the router to turn off? This is the only way to kill those, though---no IOS commands to prepare for a shutdown (like Windoze...lol)---additionally, once you hit enter after a command in a Cisco device, it takes place right away (except for maybe ip add dhcp, ddns commands, and others that need an obvious reboot). Now the other routers and switches that do have a power switch (3640 router, for example)---this kills DC to the router, so no "sudden loss of AC", and unless there is something else wrong like a module not being recognized, etc., the router would not boot into rommon.
Before you can load an IOS image to your router, you must, of course, download the appropriate image from Cisco or purchase it on CD media.
I saw a video on how to upgrade your IOS with TFTP. I thought I read somewhere that your IOS has to have a 'k' in it if you want SSH. Or can someone point to a website that explains how to read the names? Yes, normally it will erase FLASH before it moves the new IOS in.
My questions is, when you install a new IOS, does it overwrite the old one? I've never done this before so I would hate to really mess this up. Depending on the size of FLASH would determine if you can have more than 1 IOS in there.
Yes, the Cisco site is huge, nice thing is that when you "Google" most things "Cisco", links to Cisco are normally in the top 10 searchs returned. Broda CCNA, CCDA, CCAI, Network The version of code you posted c2600-is-mz.122-15.
Hope this helps, and come visit us over in the other forum here! T10is not SSH capable you will need to download a new version that has crypto capability .
