  • Efficient data transfer during computing system manufacturing and installation
    Patent number: 6807665
    Abstract: A manufacturer installs software by first partitioning storage media of the computing system into a first partition and a second partition. The manufacturer installs software bundles Into the second partition. Each software bundle is stored in form as an image. The manufacturer also installs bootable software and a user interface into the first partition. The bootable software and the user interface when run, operate to receive from a user a selection as to which of the software bundles to install in the computing system. The software bundle selected by the user is installed into the first partition while overwriting the bootable software and the user interface. After installation of the software bundle selected by the user, the bootable software, for example, can erase the installation software bundles in the second partition. This is done, for example, by overwriting the second partition with a blank file system.
