FIELD
• Embodiments of the invention relate to computer system configurations. Specifically, embodiments relate to remotely changing the system configuration and updating the system configuration utilizing a bus master device.
BACKGROUND
• A computer system includes multiple devices that are necessary for its functioning. These devices must each be started or initialized when the system is powered on or restarted. Most computer systems include a system configuration manager program that handles the basic start up and initialization of the computer system.
• In some computer systems the basic start up and initialization program or system configuration manager is referred to as the basic input-output system (BIOS). The computer system after power up or restart begins by executing the first instruction of the BIOS. The BIOS initializes the chipset, tests and initializes system memory, and tests and initializes peripheral device functionality. This process is collectively known as Power-on Self Test (POST). After system devices have been properly initialized the BIOS loads a boot-loader program. The boot-loader program is stored in the designated boot sector of a storage device such as a fixed disk. The boot-loader starts the operating system. The operating system then takes control of the computer system.
• BIOS code is firmware that is stored in a flash memory device. The BIOS code uses configuration data to program user configurable settings during system POST. BIOS configuration data is stored in a nonvolatile memory that is composed of complementary metal oxide semiconductors (CMOS). CMOS is an energy efficient technology allowing it to be supported by a back up battery when a computer system is disconnected from its main power source. Non-volatile data used during POST includes real time clock (RTC) date and time data, drive configurations, system memory settings, operating system settings, serial and parallel port settings and other system settings.

As used herein, the term ‘local machine’ is a computer system with a system configuration manager to update the configuration of the computer system. A ‘remote’ machine or application is connected to the local machine through a network or similar mechanism.Computer system101 may be a workstation, laptop, desktop or similar computer system.Computer system101 may be connected to network213 throughnetwork device119.Network213 may be a local area network (LAN), wide area network (WAN), the Internet or similar network. As used herein, the term ‘system configuration data’ refers to user configurable settings and hardware settings of a computer system that are set by a system configuration manager such asBIOS115. User configurable settings typically include operating system (OS), power management and other general settings. Hardware settings may include processor, memory, bus, graphics processor and similar speed and latency settings.

• FIG. 3 is a flowchart of one embodiment of a process for remotely updating a system. In one embodiment, each computer system may have a default or local system configuration data that is used during the initialization of the computer. This default configuration may be updated at the machine by utilization of a system configuration manager such asBIOS115 or a similar application. As used herein the term ‘system configuration manager’ refers to a program or module that manages the system configuration of a computer system locally. A BIOS may be an example of such a system configuration manager. The system configuration manager may be accessed during initialization of a computer system by the manual entry of a key sequence on the keyboard of the computer system. System settings that may be managed by the system configuration manager include device storage sizes, device speeds, CPU speed, system bus speeds, graphics settings, boot settings and similar system settings.
• In one embodiment, a user may remotely access and alter system settings without manual input at the machine to be reconfigured. A user may utilize aserver module211 to view current system settings or to generate a new configuration for the target computer system. Theserver module211 running onserver209 may send the configuration information overnetwork213 to a local machine101 (block313). For example, a system administrator may update the operating system software oflocal machine101 either locally or remotely. The update of the operating system software may allow the utilization of larger fixed disk storage sizes than was supported by the operating system before the update.Local machine101 may contain a fixeddisk125 that is larger than was supported by the operating system before the update. The system administrator may create a new system configuration forlocal machine101 including an increased size for the fixeddisk125 to better utilize fixeddisk125. This new configuration may then be sent tolocal machine101.
• In one embodiment, aclient module203 running on thelocal machine101 may receive the incoming configuration data from anetwork device119 or similar method (block315). In another embodiment, the configuration data may be applicable to multiple machines and may be broadcast to a set of machines onnetwork213. For example,client module203 may receive the new configuration sent by the system administrator viaserver module211 to enable the use of a larger space on fixeddisk125.
• In one embodiment,client module203 may write the received configuration data into a predefined memory space (block317). The predefined memory space may be located insystem memory109, fixedstorage device125, removable media drive129, CMOS or similar storage device. In another embodiment, a specialized memory device may be used to store the received system configuration data. In a further embodiment,system memory109 or similar storage device may be modified or provided with a persistent power supply such as a battery back up to maintain the system configuration data during power down or reboot ofcomputer system101. For example, the new system configuration created by the system administrator may be written intosystem memory109 orstorage device125. As used herein, the term ‘reboot’ refers to a restarting of a computer system. This restarting may or may not cause a loss of power to volatile memory and loss of data. As used herein the ‘predefined memory area’ refers to the storage area in any appropriate memory device or storage device or a combination of multiple devices where new or updated system configuration data may be stored before it is used to update the default configuration data.
• In one embodiment, the received system configuration data may be written to the predefined memory area and stored in any appropriate format. In one embodiment, the format of the stored system configuration data may match the format of the default system configuration data stored inCMOS113 or other location incomputer system101. As used herein ‘default system configuration data’ refers to system configuration data that may be stored in a non-volatile storage device such asCMOS113 and used to initialize a computer system until new or updated system configuration data updates it. This default system configuration data may have been previously updated or changed. In a further embodiment, only changes to the current system configuration are transmitted byserver module211 and saved byclient module203.
• In one embodiment, a passive updating scheme337 may be used to update the system configuration with the received configuration data. In one embodiment, when acomputer system101 is rebooted orcomputer system101 is powered on the system configuration manager may check to determine if changes to the system configuration are present (block319). If there are changes present then the changes or new configuration may be used to modify or replace the default system configuration data stored byCMOS113 or other appropriate storage device (block321). For example, after a new or updated configuration is received from a system administrator and stored in the predefined memory area either the next time the system is rebooted or powered on then the system configuration manager examines the predefined memory space to determine if it contains new or changed configuration data. If new or updated data is found, then it may be copied intoCMOS113 to replace or modify the default system configuration data. In one embodiment, the detection of updated or new data involves a comparison of the default configuration data with the received system configuration data. In another embodiment, when the received system configuration data is stored by client module203 a flag or similar indicator may be set. This indicator may be checked on reboot or power on to determine if new or updated data has been received.
• In one embodiment, afterCMOS113 or similar storage device for the system configuration data is updated or replaced, the new default system configuration data is used to initialize or start up computer system101 (block323). In some circumstances this may require another reboot before the system configuration changes may be implemented. Changes to system configuration settings that are currently utilized or already initialized by the system configuration manager at the time of the updating of the system configuration setting may not be resettable whilecomputer system101 is running. For example, after copying the new configuration settings sent by the system administrator intoCMOS113,BIOS115 may reboot the computer. During the subsequent reboot the new system configuration settings and data may be used.
• In another embodiment, anactive system325 may be used to update system configuration settings. In one embodiment, afterclient module203 has received and stored system configuration data fromserver module211, it may notify the system configuration manager, such asBIOS115, of the reception of updated or new configuration data (block327). In one embodiment, a system configuration manager may examine the updated or new configuration data to determine if the change of configuration settings can be made whilecomputer system101 is running. In another embodiment,server module211 may send an indication of whether the changes can be done whilecomputer system101 is running. In this case, the system configuration manager checks for this indication. For example, the system configuration update received bycomputer system101 may be to adjust the size of fixeddisk125 to increase its recognized capacity.Server module211 may determine thatBIOS115 and the operating system may be able to handle the dynamic change in capacity of fixeddisk drive125 and not require a reboot ofcomputer system101.
• In one embodiment, after the system configuration manager is notified regarding the new or updated configuration data, it may copy the changes or new settings into the storage area for the default configuration settings such as CMOS113 (block329). A check may then be made to determine if the changes in the settings require a reboot of computer system101 (block331). This may be accomplished by checking for a direct indication fromserver module211 or by analyzing the type of changes to the settings that were made. For example,BIOS115 may implement the increase in recognized capacity of a fixeddisk125. It may then make a determination whether this configuration change requires a reboot ofcomputer system101 to completely implement the change without causing errors.
• In one embodiment, if the changes to the system configuration do not require a reboot then the changes may be implemented andcomputer system101 continues to function with the changes indicated by the new system configuration settings (block333). If the changes to the system configuration require that the system be rebooted, thenclient module203, system configuration manager, or the operating system may initiate a reboot ofcomputer system101 to complete the change in system configuration settings.
• FIG. 4 is a flowchart of one embodiment of a process for performing a system initialization. In one embodiment, system initialization may occur whencomputer system101 is powered on or reset (block401).Computer system101 begins execution of a system configuration manager which may start the initialization of basic system components (block403). Basic system components may include the chipset, RTC and similar components. Initialization may continue by configuring all plug and play devices such as modems, graphics cards, network cards and similar peripheral cards and devices (block405).
• In one embodiment, a similar system configuration manager may check the predefined memory area to determine if the default system configuration needs to be updated (block407). This may be determined through comparison between the default system configuration data and new or updated system configuration data or by detecting an update indicator. The system configuration manager may then begin the process of copying over or updating the default system configuration settings saved inCMOS113 or similar non-volatile storage. The system configuration manager may then start to alter system settings in accordance with the changes indicated in the updated or new configuration data.
• In one embodiment, the system configuration manager may determine whether it may be necessary to reboot computer system101 (block411). This may be determined by detecting a stored indicator requiring reboot or by analysis of the changes to the system settings in the new system configuration. If a reboot is necessary the reboot process may be restarted with the new configuration data having been stored in the default configuration space. If the reboot is not necessary, then the system configuration manager may continue and complete the initialization of the components of computer system101 (block413). When the initialization is complete, the system configuration manager may call a boot-load program to start up the appropriate operating system for computer system101 (block415). The operating system then takes primary control overcomputer system101.
• In one embodiment,server module211 may send toclient module203 additional commands and information.Server module211 may indicate whether the handling of configuration information is to be handled using anactive method325 or a passive method337.Server module211 may determine when or if the target computer system should reboot during a system reconfiguration process.
• FIG. 5 is a flowchart of one embodiment of a process of performing a system configuration update utilizing a bus master device. As used herein, a ‘bus master device’ is any device that is capable of driving the internal bus ofcomputer system101. This enables the device to read and write to the memory space ofcomputer system101. A bus master device may be attached tocomputer system101 as aUSB device121, serial device, wireless device, infra red device or similar device coupled to a USB port, serial port, parallel port,1394 port (firewire) or similar port or connection device ofcomputer system101.
• In one embodiment, the bus master device may be capable of interfacing with a system management application similar toserver module211. This system management application may be able to monitor the system configuration of atarget computer system101.
• In one embodiment, the system management application may generate a system configuration and communicate this configuration to bus master device121 (block501). In one embodiment,bus master device121 may be capable of storing the configuration. In another embodiment,bus master device121 may retransmit the system configuration data by writing it to the predefined memory space (block503). For example, a USB device with a memory module may be connected to a system configuration management application that loads a system configuration into the memory module of the USB device. The USB device may then be connected to alocal machine101 and the USB device may load the system configuration data from its internal memory module into the predefined memory space oflocal machine101.
• In one embodiment,bus master device121 may support both apassive method505 and anactive method507 of updating the system configuration of a target machine. In a passive method of updating the system configuration the update may occur during the next reboot or power on ofcomputer system101. During the reboot process the system configuration manager may check for updates to the system configuration (block509). In one embodiment, the system configuration manager may make a comparison between the default system configuration stored inCMOS113 or similar non-volatile storage and new system configuration data stored in the predefined memory space. In another embodiment, the system configuration manager may detect an indicator that changes or a new configuration is to be implemented.
• In one embodiment, the system configuration manager will update the default system configuration data in CMOS or similar non-volatile storage with the new system configuration data during the start up or reboot (block511). The system configuration manager may then implement the new configuration in computer system101 (block513). In another embodiment, the system configuration manager may rebootcomputer system101 to complete the implementation of the updated system configuration settings.
• In one embodiment, anactive update system507 may be used. After the bus master has stored the new or updated system configuration data in the predefined memory space, the bus master may notify or provide an indicator to the system configuration manager that system configuration settings are to be changed (block515). System configuration manager may then copy the new or updated configuration data from the predefined memory space to the default storage area such asCMOS113 or similar non-volatile memory device or similarly update the default system configuration data (block517).
• In one embodiment, the system configuration manager may make a decision whether it is necessary to reboot to complete the implementation of the system settings (block519). The system configuration manager may determine whether reboot is necessary by analyzing the types of system configuration changes that need to be made. In another embodiment, the system configuration manager may check for an indicator received from the bus master or stored by the bus master in a predefined location.
• In one embodiment, a reboot may be necessary to complete the implementation of the updated or new system configuration settings. System configuration manager or operating system may initiate the reboot of the system and complete the implementation of the new default system settings during the start up sequence. In another embodiment, a reboot is not necessary to effect the changes to the system settings. The system configuration manager implements the updated or new configuration data stored in the default memory storage area and the operation of computer system continues.
• In one embodiment, system configuration data may also be utilized by an advanced configuration and power management interface (ACPI) or similar interface. ACPI provides methods such as load and unload methods which facilitate the loading and unloading of definition blocks used to configure hardware devices in the computer system. In one embodiment, where a reboot of the system is not necessary to implement system configuration changes, ACPI definition blocks related to the system changes may be loaded or unloaded to implement modifications to the system configuration. This may include adding new methods in a definition block. These methods may be written in ACPI source language (ASL).
• In one embodiment, the improved system configuration updating system may be implemented as software and stored on a machine readable medium. As used herein a machine readable medium may be a medium capable of storing or transmitting data and similar information such as a fixed disk, physical drive, CDROM, DVD, optical disk, wireless transmission, optical transmission, infra red transmission, and similar storage devices and transmission systems.
• In the foregoing specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes can be made thereto without departing from the broader spirit and scope of the embodiments of the invention as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
