摘要： Methods and apparatus for associating partitions in a computing device are disclosed. An example method includes, loading an operating system (O/S) kernel partition (kernel partition) and identifying one or more root filesystem (rootfs) partitions that are compatible with the loaded kernel partition. In the example method, the one or more compatible rootfs partitions are identified by comparing a set of compatibility bits of the loaded kernel partition with respective sets of compatibility bits of a plurality of rootfs partitions of the computing device. The example method still further includes selecting a rootfs partition from the one or more identified compatible rootfs partitions and loading the selected rootfs partition.

摘要： Configurations providing a non-zero threshold for verifying a root file system of an operating system stored on blocks of a boot storage are disclosed. In particular, the root file system is verified during a boot sequence for the operating system. For each block of the root file system of the boot storage, the subject technology verifies a respective block of the boot storage. A counter tracking a number of verification failures is incremented if the block fails verification. In some configurations, the subject technology determines whether the counter meets a predetermined non-zero threshold. If the counter meets the predetermined non-zero threshold, the root file system is marked as corrupted. A recovery mode for the operating system is then initiated. If the counter does not meet the predetermined non-zero threshold, the operating system is reset in order to verify the root file system during a subsequent boot sequence.

摘要： A system and method is disclosed for locking down a capability of a computer system. Hardware instructions initiate a sequence of boot cycles to launch a computer operating system on a computer-enabled device. During the boot cycles, multiple levels of boot code are verified. Each verified stage of boot code verifies a subsequent stage of boot code. If the subsequent stage of boot code cannot be verified, the verified stage locks a capability of the computer so that the subsequent stage of boot code cannot modify the capability.

摘要： A method of fabricating a semiconductor device and the device which includes initially providing a layer of silicon having a thin oxide layer thereon and a patterned layer of a masking material not permeable to at least selected oxygen-bearing species and having a sidewall disposed over said oxide layer to provide an exposed intersection of the masking material and the oxide layer. An oxygen-bearing species conductive path is then formed on the sidewall of the masking material extending to the exposed intersection for conducting the selected oxygen-bearing species. A sidewall layer of a material different from the conductive path is formed on the conductive path. An oxygen-bearing species is then applied to the exposed intersection through the path and a thick oxide surrounding the masking material is fabricated concurrently or as a separate step. The masking material is preferably silicon nitride, the path is preferably silicon oxide and the sidewall layer is preferably silicon nitride.
