Abstract

A method and computer program is provided whereby a personal digital assistant or personal palm-type device of very limited RAM capacity can make available sufficient RAM capacity to store a complete global software distribution package so that the appropriate software or software upgrade may be installed into the device from the global package. The method includes the steps of: first deleting from the personal palm-type device RAM all application programs other than application programs required to support the device operating system to receive the global software distribution package and loading the received global software distribution package into the now available device RAM. Then, the software from the global package needed to make the distribution or upgrade of the device is loaded from the global distribution package into the device programmable ROM where all of the device software is permanently stored. Upon the completion of this distribution, the global software distribution package is deleted from said RAM, and all previously deleted application programs are then downloaded from the programmable ROM back into said device RAM. In most operations, the global software distribution package is transmitted to the personal palm-type device over a communication network, particularly the World Wide Web or Internet, either through linked modems or through wireless mobile communications.
