摘要： An insertion and identification scheme between the main unit of a Personal Digital Assistant (PDA) or handheld device and an option pack. Upon insertion, the hardware interface invokes a device manager on the main unit that interrogates the option pack on its features without significantly impacting battery life. The interrogation includes data on drivers, applications, configuration and miscellaneous requirements of the option pack. This identification process allows the option pack to store information, drivers and applications on the option pack, so the main unit does not have to use its memory to store information on a large number of option packs. Further, the insertion scheme provides a means of checking the power availability in the main unit before allowing the option pack to fully power-on.
摘要翻译：个人数字助理（PDA）或手持设备的主单元与选件包之间的插入和识别方案。插入后，硬件接口调用主机上的设备管理器，在其功能上询问选件包，而不会显着影响电池寿命。询问包括有关选件包的驱动程序，应用程序，配置和其他要求的数据。此识别过程允许选件包在选件包上存储信息，驱动程序和应用程序，因此主机不必使用其内存来存储大量选件包上的信息。此外，插入方案提供了在允许选项包完全通电之前检查主单元中的电力可用性的手段。

摘要： A Personal Digital Assistant (PDA) or handheld device comprising a main unit and an option pack, wherein the option pack stores all of the application software and drivers. Upon insertion, the hardware interface invokes a device manager on the main unit that interrogates a memory device on the option pack. The interrogation includes data on drivers, applications, configuration and miscellaneous requirements of the option pack. This identification process allows the option pack to store information, drivers and applications on the option pack, so the main unit does not have to use its memory to store information on a large number of option packs. Once the option pack and its applications are identified, the device manager on the main unit retrieves the applications and drivers from a separate memory device on the option pack and downloads the applications and drivers onto the main unit. Upon de-installation of the option pack from the main unit, the applications and drivers are removed from the main unit.
