My 2 cents...

_c/ffcprt2/fcf010.htm#1001503

>> When loading a default system image from a network server, the router
uses the configuration register settings to determine the default system
image filename for booting from a network server. The router forms the
default boot filename by starting with the word cisco and then appending the
octal equivalent of the boot field number in the configuration register,
followed by a hyphen (-) and the processor type name (cisconn-cpu). See the
appropriate hardware installation guide for details on the configuration
register and the default filename.

based on this, configure the following cmd on r2:

 tftp-server flash flash:actual_image_name alias ciscox-C2600

where r1's boot field is set to x and the "processor type name" is C2600
(guessing here based on

If the boot field is 2 through f, if there aren't boot system commands
on configuration file, if there isn't a valid image on flash device, the
router tries to boot from the network using the "default image name".
Now these names depend on the router's plataform, ie, c7200, c2600, etc.
If r1 is a c2600, r2 has to have ios for r1 loaded into his flash with
the name, and with command tftp-server flash:default-image-name-c2600
