I have a 2514 router that I would like to use to study with, but I can not update the ios because it is read only. Here is a show version of the router.

Re: 2514 router ios update possible?

to answer your questions,
1) no, there is no jumper that you can change to make the flash read/write
2) yes, you need to change the config-reg
3) the IOS can be updated, although on a router with only 4MB of RAM and 8MB of flash, you're going to be severly limited in what version of IOS you will be able to load and run with that limited amount of memory.
