Description

PORTABLE DEVICE COMPRISING A BIOS SETTING
BACKGROUND
[0001] Computers typically comprise executable code referred to as the basic input/output system (BIOS) code. The BIOS code is executed to initialize (boot- up) the computer as well as to provide various interfaces to low-level functions of the computer such as access to storage drives, interaction with input devices, etc. One or more settings are typically associated with a computer's BIOS. An example of such a setting is the enabling or disabling of or more of the computer's ports. Changing a computer's BIOS settings to suit a user's preferences can be time-consuming and cumbersome. Further, multiple users might desire to each have their customized set of BIOS settings. Storage space internal to the computer to store BIOS settings for multiple users is limited.
BRIEF DESCRIPTION OF THE DRAWINGS
[0002] For a detailed description of exemplary embodiments of the invention, reference will now be made to the accompanying drawings in which: [0003] Figure 1 shows a system in accordance with an embodiment of the invention; and
[0004] Figure 2 shows a method in accordance with an embodiment of the invention.
NOTATION AND NOMENCLATURE
[0005] Certain terms are used throughout the following description and claims to refer to particular system components. As one skilled in the art will appreciate, computer companies may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function. In the following discussion and in the claims, the terms "including" and "comprising" are used in an open-ended fashion, and thus should be interpreted to mean "including, but not limited to... ." Also, the term "couple" or "couples" is intended to mean either an indirect, direct, optical or wireless electrical connection. Thus, if a first device couples to a second device, that connection may be through a direct electrical connection, through an indirect electrical connection via other devices and connections, through an optical electrical connection, or through a wireless electrical connection.
DETAILED DESCRIPTION
[0006] Figure 1 shows a system 50 in accordance with an embodiment of the invention. The system 50 shown in Figure 1 may be representative of a wide variety of electronic systems. In accordance with at least one embodiment of the invention as will be discussed herein, at least one such system comprises a computer. As shown, computer 50 comprises a processor 52, volatile memory 54, north and south bridges 56 and 55, respectively, a user authentication device 57, non-volatile storage 58, and a token reader 64. In the embodiment of Figure 1 , the processor 52 and volatile memory 54 couple to the north bridge 56. The south bridge 55 couples to the north bridge 56 as well as to user authentication device 57, non-volatile storage 58, and token reader 64.
[0007] The non-volatile storage 58 may comprise in some embodiments, a read only memory (ROM). In this illustrated embodiment, ROM 58 comprises storage for a basic input/output system (BIOS) 60 and, as such, is referred to as a BIOS ROM. During initialization, the BIOS code 60 begins to execute from the BIOS ROM and is copied to the computer's volatile memory 54 for subsequent execution therefrom. At least a portion of the BIOS code 60 initializes the computer and causes the computer to transition to a fully operational state. [0008] In the embodiment shown in Figure 1, one or more BIOS settings 62 are also stored in the BIOS ROM 58. Such settings are used in connection with, or by, the BIOS code 60. Examples of the BIOS settings 62 comprise any one or more of an identity of a computer port to be enabled or disabled, a type of input device to be enabled, a security setting, a wireless communication setting, and a boot option (e.g., device boot order). When used, BIOS settings are used by the BIOS code 60. [0009] In accordance with an embodiment of the invention, a portable token 70 can be inserted into the token reader 64. The token 70 may comprise any suitable type of portable storage device that can be coupled to, or decoupled . from, the computer 50. Examples include a smart card and a universal serial bus (USB) storage device. The token reader 64 comprises an interface for the token 70 to the computer 50. In embodiments in which the token 70 comprises a smart card, the token reader 64 comprises a smart card reader. In embodiments in which the token 70 comprises a USB storage device, the token reader 64 comprises a USB port which, in turn, may comprise a USB controller. Further still, the token reader 64 in some embodiments is implemented as a biometric reader such as a fingerprint scanner. The token 70 has one or more BIOS settings 72 stored thereon (e.g., in non-volatile storage such as flash memory in or associated with the token 70).
[0010] Figure 2 illustrates a method embodiment comprising actions 100-110. At 100, a user installs the token 70 in the computer 50. For example, in embodiments in which the token comprises a smart card, the smart card is inserted into a smart card reader associated with the computer. In embodiments in which the token 70 comprises a USB storage device, the token is connected to a USB port. At 102, the user causes the computer to begin booting (initializing) by, for example, pressing a power-on button. Some systems permit user authentication to be a feature that can be enabled and disabled, while in other systems whether a user is to be authenticated is not a feature that can be selectively enabled or disabled. If the computer has been configured to require a user to be authenticated before completing the boot process, at 104 the user is so authenticated. In some embodiments, this action is performed by the BIOS code 60. User authentication can be performed in a variety of ways. In one embodiment, the user authentication device 57 (Figure 1) comprises an input device such as a keyboard and action 104 is performed by requiring the user to enter a correct password via the keyboard. In other embodiments, the user authentication device 57 comprises a biometric device such as a fingerprint or retinal scanner and the user is authenticated upon a successful biometric verification. In yet other embodiments such as those embodiments in which the token comprises a smart card, user authentication is stored on the token 70 and such information is used to authenticate the user. In other embodiments of the invention, user authentication, and thus action 104, is not performed. [0011] If the user has been successfully authenticated in those embodiments in which user authentication is implemented, or if no user authentication is implemented, control passes to decision 106 at which a determination is made as to whether a token is installed in the system (per action 100) and, if so, whether the installed token comprises one or more BIOS settings. In some embodiments, the BIOS code 60 performs decision 106 by, for example, searching for a predetermined signature on a token 70. The signature may comprise a particular character string, bit string or a file name, or other suitable identifier of a BIOS setting. In at least some embodiments, the signature correlates the identity of the user to the BIOS setting(s) in accordance with any suitable technique. In one example, the signature includes a value that corresponds to a user-unique value (e.g., a password, fingerprint, etc.) that was used to authenticate the user as explained above. This correlation permits the BIOS setting(s) 72 on the token to be authenticated for the particular user of the token. Thus, in some embodiments, not only is the user authenticated, but the BIOS setting(s) 72 on the token is also authenticated to the user.
[0012] If no token has been installed in the computer or if a token has been installed, but the predetermined signature is not found, the BIOS code 60 determines that no BIOS setting is available on a token. In such a case, the BIOS settings are applied from storage internal onto the computer (action 110). Applying BIOS settings includes, in at least some embodiments, loading the settings into the BIOS 60 or otherwise making the settings available for use by the BIOS 60. The internal storage may comprise the BIOS ROM 58, which includes BIOS settings 62, or other suitable non-volatile storage (e.g., battery- backed RAM memory). If, however, the predetermined signature is found on a token 70, at 108 the BIOS settings are applied from the token 70 onto system 50. In the example of Figure 2 and all other examples in this disclosure, the BIOS settings may comprise a single setting or multiple settings. [0013] The embodiment of Figure 2 and other embodiments discussed herein permit multiple users to easily provide their own customized BIOS settings to a computer. Further, a single user, such as a network administrator, can readily reconfigure each of a plurality of computers to perform, for example, a maintenance operation.
[0014] In the example of Figure 2, the BIOS settings are loaded either from the token 70 (settings 72) or from storage internal to the computer (settings 62). In accordance with an alternative embodiment, BIOS settings may be loaded both from the token 70 and the computer's internal storage. For example, the token 70 may contain some, but not all, of the BIOS settings. Accordingly, those settings (or single setting) that are present on the token 70 are loaded into the computer and the remaining setting(s) are loaded from the computer's internal storage. [0015] In accordance with yet another embodiment, the BIOS settings are loaded first from the computer's internal storage. Then, if a token 70 is installed in the computer and the token contains any BIOS settings, such token-based BIOS settings over-write whatever corresponding BIOS settings were loaded (applied) from the computer's internal storage. Thus, to the extent a token has any BIOS settings, such settings are given priority over the BIOS settings from the computer's internal storage. In this embodiment, the token 70 comprises all, or less than all, of the BIOS settings. Those BIOS settings loaded from the computer's internal storage that are not also present on the token 70 are, of course, not overwritten and remain intact as loaded from the internal storage. [0016] The above discussion is meant to be illustrative of the principles and various embodiments of the present invention. Numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. It is intended that the following claims be interpreted to embrace all such variations and modifications.
