on the router then off the router your ios is install on the router then off the router your ios is install
To install IOS on a Cisco 2600 router, first, download the appropriate IOS image from Cisco's website (ensure you have the necessary permissions). Next, connect to the router via console cable and use a terminal emulator to access the command line. Transfer the IOS image to the router using TFTP or a similar method, then use the copy tftp flash command to copy the image to the router's flash memory. Finally, configure the router to boot from the new IOS image by updating the boot system command in the configuration and rebooting the router.
There is a question floating around that says "when the running-config directs the router to do so"... this is utter rubbish, how can the running-config tell the router to do so when there is no IOS?... no IOS means no running-config. To answer your question about when would the IOS held in ROM be used to boot the router?... when the IOS cannot be found by the Bootstrap it will eventually look in the ROM for it. It will look in the default location in the flash memory, if there is no IOS in the flash, then it will try to locate one from a TFTP server. If it still cant find an IOS then it will look in the ROM for a scaled down version of the IOS and load it from there. I hoep this put an end to the other false answers that are floating around.
A router stores its IOS (Internetwork Operating System) in non-volatile memory, typically in Flash memory. This allows the IOS to persist even when the router is powered off or restarted. The configuration files, which define how the router operates, can also be stored in NVRAM (Non-Volatile Random Access Memory) or Flash, depending on the setup. This ensures that the router can boot up with the correct operating system and settings.
What is the purpose of using the copy tftp flash command on a router? to back up the current IOS image to a server to restore the IOS image from a server to back up the router configuration to a server to restore the router configuration from flash
It is a way to compress an existing IOS so that a newer IOS version can be co-installed on a router.
ios 8 can be installed on ipad by first registering or have your device UDID registered by a developer and then download the iOS 8 beta and install it on your ipad
To display the current IOS version and feature set running on a router, you can execute the command show version from user mode. This command provides detailed information about the IOS version, the router's hardware, memory, and feature set. Alternatively, show version | include Version can be used to filter the output specifically for the IOS version.
If a router cannot locate an IOS in flash memory, it will first check the ROM (Read-Only Memory) for a bootstrap program to initiate the boot process. If a valid IOS is not found there, the router will then attempt to load the IOS from a TFTP (Trivial File Transfer Protocol) server over the network, assuming it has been configured to do so and can reach the server.

To install the router ensure it is the one you want wireless or hardwired. You will then need to utilize the CD to install the necessary drivers to your device. Finally, hook up the devices to the router.
