BACKGROUND  
         [0001]    1. Field  
           [0002]    The present disclosure relates to allowing the utilization of an override group of hardware settings and, more particularly, to allowing the utilization of a customized group of hardware settings without the modification of a platform group of hardware settings.  
           [0003]    2. Background Information  
           [0004]    Typically, the operation of a computer or processing system (hereafter, “computer”) may be divided into two stages, pre-boot and runtime. The pre-boot process or phase often comprises starting or resetting a computer. When first turned on (cold boot) or reset/rebooted (warn boot), a computer executes the software that loads and starts the computer&#39;s operating system and prepares it for use. Thus, the computer can be said to pull itself up by its own bootstraps. The runtime process or phase often occurs after the pre-boot phase and includes the execution of an operating system and other user applications. The runtime phase is typically the phase that users interact with the computer. Thus, the computer can be said to being running application programs.  
           [0005]    During pre-boot, the computer is first powered on and has very limited capabilities because the volatile memory contains random data and no operating system is running. To begin the pre-boot phase, the processor is often reset to a known state and instructions found at a pre-defined location are executed. Traditionally, this pre-defined location was mapped to a non-volatile memory or firmware referred to as a Basic Input/Output System (BIOS). The BIOS often includes several low-level procedures to handle the hardware components that comprise the computer. Traditionally, each hardware component is associated with an individual driver that may allow the hardware device to be configured during the pre-boot phase.  
           [0006]    A BIOS typically includes an embedded ROM table with a default hardware configuration setting. Often, the topology of the ROM table is unique to the manufacturer of the specific firmware or BIOS, and editing of the table requires a specialized tool from the BIOS vendor. Alternatively, the default hardware configuration settings may be mapped through a legacy Complementary Metal Oxide Semiconductor (CMOS )map. Once again, the CMOS map is often unique to each BIOS vendor. This uniqueness and reliance on vendor tools makes it difficult to modify the default hardware settings for a computer or platform. In this context, a “platform” is a particular arrangement of hardware components that constitute an embodiment of a hardware system.  
           [0007]    Often, original equipment manufacturers (OEMs) and hardware system retailers would like to buy platforms and hardware components from various component manufactures, but still maintain a constant “look-and-feel,” or brand, across their product line. Typically, they achieve this goal by having the platform or BIOS vendor write or compile a special BIOS with the desired “look-and-feel.” 
           [0008]    Even slight modifications to a BIOS can cause compatibility, integrity or security issues. For example, often BIOS firmware is compressed, and cryptographically signed. The firmware may be signed in order to protect it against tampering (i.e., the Chernobyl virus). Because a new BIOS may need to be created every time a new components are added or removed to make a new hardware system. This, typically, entails a large amount of support, validation, and accounting management.

     DETAILED DESCRIPTION  
       [0012]    In the following detailed description, numerous details are set forth in order to provide a thorough understanding of the present disclosed subject matter. However, it will be understood by those skilled in the art that the disclosed subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as to not obscure the disclosed subject matter.  
         [0013]    [0013]FIG. 1 is a flowchart illustrating an embodiment of a technique for allowing the utilization of an override group of hardware settings in accordance with the disclosed subject matter. In one embodiment, the technique may include block  105  that illustrates that the system may be reset, and block  190  that illustrates the booting of the operating system (OS). In short, it is contemplated that one embodiment of the disclosed subject matter may occur during the pre-boot phase (i.e., between block  105  and block  190 ). However, the disclosed subject matter is not limited to the pre-boot phase and performing the technique, in whole or part, during the runtime phase is contemplated.  
         [0014]    Block  110  illustrates that, in one embodiment, a substantial portion of the pre-boot firmware may initialize and test the integrity of the hardware system. In one embodiment, the hardware system may perform a variation of a power-on self-test (POST) that tests various system components, such as, for example, Random Access Memory (RAM), the disk drives, and the keyboard, to see if they are properly connected and operating. If problems are found, these routines may alert the user by sounding a series of beeps or displaying a message, often accompanied by a diagnostic numeric value, to the standard output or standard error device (usually the screen). In another embodiment, the hardware system may perform actions substantially compliant with those defined in the Extensible Firmware Interface (EFI) specification. Extensible Firmware Interface (EFI) Specification, ver 1.02, Dec. 12, 2000, Intel Corp. (hereafter, “the EFI specification”). However, this is merely one specific embodiment of the disclosed subject matter.  
         [0015]    Block  120  illustrates that a decision may be made whether to initialize the hardware system to a default hardware configuration. It is contemplated that a number of activities may elicit a decision to restore the hardware system configuration to a default value. In one embodiment, the hardware system may detect that a number of attempted system boots or initializations has not resulted in a successful hardware system boot. A decision may then be made to attempt to boot the hardware system utilizing a default group of hardware settings. In another embodiment, the system may detect that it has never been booted before, and select the default group of hardware settings. However, these are merely illustrative embodiments and it is contemplated that other activities or conditions, internal or external to the system, may elicit a decision to restore the hardware system configuration to a default value  
         [0016]    Block  150  illustrates that if the system is not restored to a default setting, a preceding or prior group of hardware settings may be utilized to initialize the hardware system. In one embodiment, this group of settings may have been utilized to successfully boot the hardware system during the preceding or prior boot-up phase. It is contemplated that this group of settings may be stored in the same manner as any default group of settings, described in relation to blocks  160  &amp;  170  below, or stored in a different manner. In one embodiment, a user may configure or manually edit the group of hardware settings.  
         [0017]    Block  140 , on the other hand, illustrates that if the system is to be initialized utilizing a default group of hardware settings, a particular default group of hardware settings may be selected from a plurality of default groups of hardware settings. In one embodiment, an “Override Variable” may exist that dictates which of the plurality of default groups of hardware settings is to be used. It is contemplated that this variable may be stored or assigned a value utilizing a variety of techniques, such as, for example, hardwired, hardcoded, only editable utilizing a specialized tool, user editable, or dynamically generated based upon the hardware system or groups of settings.  
         [0018]    Block  160  illustrates that one of the plurality of groups of hardware settings may include, in one embodiment, a platform specific group of hardware settings. Equipment manufacturers may sell or design a “bare-bones” or standardized hardware system platform. This system may subsequently be expanded or otherwise altered. In this embodiment, the platform specific group of settings may provide settings for such a standardized hardware system platform. Such as group of settings may be a baseline group of settings for the hardware system platform. It is contemplated that, in some embodiments, the standardized hardware system platform need not be a “bare-bones” system and may be quite elaborate.  
         [0019]    In one embodiment, the platform specific group of hardware settings may be stored as a compressed and/or cryptographically signed binary image. It is contemplated that the image may not be properly altered without specialized tools. It is contemplated that the cryptographic signature may facilitate the detection of unauthorized alteration of the platform specific group of hardware settings. In one embodiment, the platform specific group of hardware settings may be stored within a non-volatile memory, such as, for example, a firmware. However, it is contemplated that the platform specific group of hardware settings may be stored within or received utilizing other machine accessible media.  
         [0020]    In one specific embodiment, the group of hardware settings may include data in an Internal Form Representation (IFR) format. This data may be formatted to include a series of configuration sets. Each configuration set may include an encoded opcode that contains the description of the type of setting and a series of tokenizing strings to enable the creation of human readable questions and possible answers relating to the hardware setting. For example, one embodiment of a configuration set may involve the amount of memory allocated for a hardware component, such as, for example, a video buffer. The configuration set may include an opcode denoting that the configuration has 3 possible options, a question string, such as, “Buffer Size,” three option strings, such as, “32MB,” “64MB,” and “128MB,” and a default value representing the “64MB” option. Of course, this is merely one specific embodiment of the disclosed subject matter and other hardware setting or configuration option data and values are contemplated. It is also contemplated that the hardware setting or configuration option data may include a series of sub-sets of string values. Each sub-set may correspond to a different human langue, such as, for example, U.S. English, U.K. English, French, or Chinese. It is contemplated that these various sub-sets may be selected based upon a user or pre-defined global or local setting.  
         [0021]    It is contemplated that, in one embodiment, the settings stored in an Internal Form Representation (IFR) or other standardized format may be stored in a format such as, for example, an extensible markup language (XML) format, a hypertext markup language (HTML) format, a compressed binary format, or an encrypted binary format. It is contemplated that the group of hardware settings may be viewable and, in some embodiments, editable, via a runtime application, such as, for example a web browser.  
         [0022]    Block  170  illustrates that one of the plurality of groups of hardware settings may include, in one embodiment, a customized group of hardware settings. Equipment manufactures may sell or design a “bare-bones” or standardized hardware system platform. This system may subsequently be expanded or otherwise altered. In one embodiment, a retailer or equipment manufacturer may wish to alter the standardized hardware system in some way. It may be undesirable to alter the platform specific group of hardware settings, illustrated by block  160 . Therefore, in this embodiment, a customized group of hardware settings may be used as an alternate group of default hardware settings.  
         [0023]    In one embodiment, the customized group of hardware settings may leverage the platform specific group of hardware settings. For example, the customized group may only include a sub-set of the settings found in the platform specific group of hardware settings. This sub-set may be used instead of, or override, the settings found in the platform specific group of hardware settings. It is contemplated that the customized set of hardware settings may include settings not included within the platform specific group of hardware settings. In another embodiment, the customized group of hardware settings may function as a complete alternative to the platform specific group of hardware settings. It is contemplated that, in one embodiment, the customized group of hardware settings may allow a retailer or other manufacturer a technique to maintain a constant “look-and-feel,” or brand, across their product line.  
         [0024]    In one embodiment, the customized group of hardware settings may be stored in any of the manners and formats described above regarding the platform specific group of hardware settings. It is contemplated that customized group of hardware settings may be stored within the same non-volatile memory as the platform specific group of settings. In one embodiment, the customized group of settings may be appended, either contiguously or continuously, to the platform specific group of settings. Alternately, the customized group of settings may be stored utilizing a separate non- volatile memory. It is contemplated that the non-volatile memory may be one non-volatile memory or a number of separate non-volatile memories each storing the group of hardware settings, in whole or part.  
         [0025]    Block  180  illustrates that, once a proper group of hardware settings is selected, the various hardware components of the hardware system may be initialized. It is contemplated that these settings may be written directly to the hardware devices, to a hardware configuration data file or section of memory within the hardware device, to a central database, or to a variety of other locales. It is also contemplated that the new settings may take effect immediately, during a portion of the pre-boot phase, or during the next reset of the system.  
         [0026]    [0026]FIG. 2 is a block diagram illustrating an embodiment of an apparatus  200  and a system  201  that allows the utilization of an override group of hardware settings in accordance with the disclosed subject matter. It is contemplated that an embodiment of such a system may take many forms, such as for example, everything from small handheld electronic devices, such as personal data assistants and cellular phones, to application-specific electronic devices, such as set-top boxes, digital cameras, and other consumer electronics, to medium sized mobile systems such as notebook, sub-notebook, and tablet computers, to desktop systems, workstations, and servers. However, the system is not limited to the forms described above and other forms are contemplated.  
         [0027]    In one embodiment, the hardware system  201  may include apparatus  200  and a plurality of hardware devices or components  290  that are capable of being configured with a group of hardware settings. It is contemplated that the hardware system  201  and apparatus  200  may be capable of performing the technique illustrated by FIG. 1 and described above.  
         [0028]    In one embodiment, the apparatus  200  may include a hardware initializor  210  to configure a hardware system  201  or a plurality of hardware devices  290  utilizing a group of hardware settings. The apparatus may also include a default setting restorer  220  to determine if a hardware system should be configured utilizing a default group of hardware settings. If not, the hardware initializor may initialize the hardware system utilizing the prior group of hardware settings  235  stored within non-volatile memory  230 .  
         [0029]    If the system is determined to be initialized using a default group of hardware settings, override configuration driver  240  may select a default group of hardware settings to use from a plurality of hardware settings. One setting may include the platform specific group of settings  255 , stored within non-volatile memory  250 . Another embodiment may include the customized group of hardware settings  265 , stored within non-volatile memory  260 . It is contemplated that the override configuration driver may itself be stored within a non-volatile memory.  
         [0030]    The techniques described herein are not limited to any particular hardware or software configuration; they may find applicability in any computing or processing environment. The techniques may be implemented in hardware, software, firmware or a combination thereof. The techniques may be implemented in programs executing on programmable machines such as mobile or stationary computers, personal digital assistants, and similar devices that each include a processor, a storage medium readable or accessible by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and one or more output devices. Program code is applied to the data entered using the input device to perform the functions described and to generate output information. The output information may be applied to one or more output devices.  
         [0031]    Each program may be implemented in a high level procedural or object oriented programming language to communicate with a processing system. However, programs may be implemented in assembly or machine language, if desired. In any case, the language may be compiled or interpreted.  
         [0032]    Each such program may be stored on a storage medium or device, e.g. compact read only memory (CD-ROM), digital versatile disk (DVD), hard disk, firmware, non-volatile memory, magnetic disk or similar medium or device, that is readable by a general or special purpose programmable machine for configuring and operating the machine when the storage medium or device is read by the computer to perform the procedures described herein. The system may also be considered to be implemented as a machine-readable or accessible storage medium, configured with a program, where the storage medium so configured causes a machine to operate in a specific manner. Other embodiments are within the scope of the following claims.  
         [0033]    While certain features of the disclosed subject matter have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes that fall within the true spirit of the disclosed subject matter.
