A method to update information including code and data in a non-volatile memory reliably and efficiently to avoid loss of information during the loading process and to minimize aircraft service downtime in an In-Flight Entertainment System (IFES). The non-volatile memory is partitioned into two sections: one section contains the currently valid information and the other is available for loading the new information. A section pointer is used to keep track of the currently valid section and to select the loading section. The new information is loaded to the selected loading section. A validation procedure is performed to determine if the loading is successful. When the loading of the new information is successfully completed, the section pointer is updated to point to the newly loaded section.

[ What is claimed is:] [1.]1. In an In-Flight Entertainment System (IFES) having a processor coupled to a non-volatile memory, a method for loading new information into the non-volatile memory in order to replace a current information, the method comprising:partitioning the non-volatile memory into at least two sections, a first section of the at least two sections containing the current information;maintaining a section pointer for use by the processor for accessing the non-volatile memory and selecting a second section of the at least two sections, the second section not containing the current information;loading the new information into the second section of the at least two sections as indicated by the maintained section pointer;validating the new information after it is loaded into the second section;updating the section pointer to indicate that current information is stored in the second section after the loaded new information is validated, wherein the section of the first and second sections not containing the current information is used for loading subsequent new information to replace the current information.
