you can use multiple protocols but tftp or ftp can be fairly common and easier to use than scp, same process for most cisco devices routers /switches etc
setup your tftp server on your pc plenty of freeware versions available , give your self an ip on the lan make sure you can reach the router , turn off local firewall on your pc while doing the tftp transfer
On cisco side these commands as an example , start with the copy tftp then hit return and it will bring up each prompt
c-MSFC15# copy tftp flash Address or name of remote host ? 172.16.84.119 Source filename ? c6msfc2-jsv-mz.121-8a.E5 Destination filename [flash]? c6msfc2-jsv-mz.121-8a.E5 Accessing tftp://172.16.84.119/c6msfc2-jsv-mz.121-8a.E5... Loading c6msfc2-jsv-mz.121-8a.E5 from 172.16.84.119 (via Vlan1):
then set the boot statements save the config and reload the router
boot-start-marker boot system flash:image name from flash boot-end-marker
I think the 1841 may support multiple boot statements. If it does, the first valid boot statement will be used, and newly added boot statements append at the end of the list. (I.e. you may need to explicitly remove old boot statement[s] from the config.)
You may find you have insufficient flash space to load a new IOS image. If you do, you may need to remove existing files. On an 1841, I believe you can also remove the currently running image. Ideally save a copy of such before you delete it. Also, if you somehow reload the device before the new image is loaded, you may need to recover from ROMMOM mode.
You may also find other media might be supported for booting, such as USB stick or CF modules (I don't know, w/o research, what are all your options with an 1841).
