[SNIP - directions on booting from ROM]

Be sure your ROM supports the new IOS rev or it will not come back properly.

Also note, a 2501 booted from ROM does not have full functionality.  For 
instance, most older ROMs did not support FR sub-interfaces.  In fact, some 
older ROMs did not even support ip routing, so you had to use the "ip 
default-gateway" command or have a TFTP server on the same 
network.  (The  default-gateway command is ignored if ip routing is running.)
