rommon 2 > reset
If the router remains in ROMmon, follow the
procedure described in
ROMmon Recovery for the
Cisco 1700 Series
Router.
Set the configuration register to 0x2102 and reload
the router. There is no need to save the running
configuration before reloading:
router(boot)#configure terminal
Enter configuration commands,
one per line. End with CNTL/Z.
router(boot)(config)#config-register 0x2102
router(boot)(config)#end
router(boot)#reload
System configuration has been modified.
Save? [yes/no]: no
Proceed with reload? [confirm]
Note: The config-register command is the only
Cisco IOS software configuration command that
doesn't get saved in nonvolatile RAM (NVRAM). It
changes the configuration register immediately, but
this only takes effect during the next boot.
The Flash card is removed or badly inserted. Verify
the presence of the Flash card by running the
flash command:
router(boot)#show flash
%Device in REMOVED state
Insert or reseat the Flash. If the problem persists,
replace the Flash card. If that doesn't resolve the
problem, replace the router.
The Flash is empty or the filesystem is corrupted.
Copy a valid image on the Flash, and while copying,
you will be prompted to erase the old Flash (if one
exists). Then reload the router.
Refer to
Software Installation and Upgrade
Procedures
for instructions on how to copy a valid
image onto the Flash.
This message only occurs when loading images that
run from RAM. Since 1700 routers support images
