By partitioning the flash memory you are creating two logical areas in which data can be stored and accessed by the router. This allows the administrator to write an IOS image to one partition of the flash while a separate image is running in the other partition.
One advantage to this method is that no router downtime is required to upload a new IOS image, whereas using the Flash Load Helper requires a minor amount of router downtime.
i read the following in ur giving link:""one image acting as a backup for the other. Therefore, if a downloaded image fails to boot for some reason, the earlier running, good image is still available. Each bank is treated as a separate device""
do i need to tell the IOS From where will boot if the the imahe its failed?
