Abstract
A portable computing device, in which an internal non-volatile memory drive that is used to boot to a functional device GUI is automatically swapped with a temporary RAM drive if the internal non-volatile memory drive is found to be corrupted. The non-volatile memory is typically Flash memory, but the principle of the present invention can be applied to any kind of non-volatile memory that could become corrupted. Default configuration files may be automatically copied to the RAM drive. These may, for example, allow at least emergency voice calls to be made.
Claims23
A portable computing device controlled by an operating system, in which, if the operating system is intact but an internal non-volatile memory drive that is used to boot the device to a functional GUI is found to be corrupted, then the non-volatile memory is automatically swapped with a temporary RAM drive to enable the operating system to boot.
A method of enabling a portable computing device to boot up to a functional GUI when its resident operating system is intact but an internal non-volatile memory drive that is normally used to boot up from is found to be corrupt, comprising the step of automatically swapping the corrupt non-volatile memory drive with a temporary RAM drive to enable the resident operating system to boot.
Operating system software, for a portable computing device comprising an internal non-volatile memory drive that is normally used to boot up the device to a functional GUI, in which the operating system software automatically swaps the non-volatile memory drive with a temporary RAM drive if the non-volatile memory drive is found to be corrupt to enable the operating system software to boot.
