Abstract (en)
[origin: WO9854642A1] A method and device which allow for the failsafe downloading of system software from a network server, without requiring additional memory. The system software is structured to consist of a primary partition and a secondary partition. The primary partition contains the software required to download the secondary partition, as well as the software to download a new primary partition. At all times, a verified copy of either an old or a new primary partition is present in memory, thereby allowing for a reexecution of the downloading process, in the event that the download process is interrupted or the received partition is corrupted.
