Validating firmware

Firmware such as the ROM BIOS of a personal computer may contain only elementary basic functions of a device and may only provide services to higher-level software.Firmware such as the program of an embedded system may be the only program that will run on the system and provide all of its functions.is a computer program that provides the low-level control for the device's specific hardware.Firmware can either provide a standardized operating environment for the device's more complex software (allowing more hardware-independence), or, for less complex devices, act as the device's complete operating system, performing all control, monitoring and data manipulation functions.

The BIOS may be "manually" updated by a user, using a small utility program.The firmware manifest may be a location-specific firmware manifest corresponding to a geographical location of the apparatus and/or computing device including the locally stored firmware., further comprising code that identifies a geographical location of the apparatus, wherein acquiring the firmware manifest comprises downloading a location-specific firmware manifest corresponding to the identified geographical location.determining a characteristic for each logical section, the characteristic selected from the group consisting of: a type of data stored in the logical section, a size of the logical section, and checking data for the logical section,wherein comparing the local firmware manifest to the firmware manifest comprises comparing, for each of the plurality of logical sections, a local firmware manifest characteristic to a firmware manifest characteristic., further comprising identifying a geographical location of the apparatus, wherein accessing the firmware manifest comprises downloading a location-specific firmware manifest corresponding to the identified geographical location., wherein validating contents of the firmware using the firmware manifest comprises comparing, prior to installation of the firmware, portions of the firmware to expected values indicated by the firmware manifest.creating a locally generated firmware manifest from the locally stored firmware, wherein validating contents of the locally stored firmware using the firmware manifest comprises comparing the locally generated firmware manifest to the firmware manifest., further comprising prompting a user to install the locally stored firmware in response to successfully validating the locally stored firmware, wherein validating the locally stored firmware comprises examining the locally stored firmware in an uninstalled state.All of the connected servers, storage devices, and switches should be present in the output of these commands.The firmware monitors the buttons, controls the LEDs, and processes the button presses in order to send the data in a format the receiving device, in this case, a television set, can understand and process.In fact, the television's mother board has a complex firmware too.

The apparatus may also include code that generates a local firmware manifest from the firmware, wherein validating the contents of the firmware includes comparing the local firmware manifest to the firmware manifest.
