Some series of routers during startup uncompress the
IOS into RAM, whereas some other series of routers run
the IOS from flash. In the later case you can't erase
the flash while normal bootup of the router.
You have to change the confregister to 0x2101 to boot
from RXBOOT mode. From where you load the new IOS or
erase the flash.
Regards.
