Method, system, and computer-readable medium for updating the firmware of a computing device via a communications network
A method for updating the firmware of a computing device via a communications network is provided. A client computer having firmware to be updated boots into a preboot execution environment (“PXE”). A broadcast request is transmitted by the PXE that requests the network location of a server computer operative to provide a firmware update program. The broadcast request also requests the name of the firmware update program. Once the response to the broadcast request is received, the client computer transmits a request to the server computer for the firmware update program. The server computer transmits the firmware update program to the client computer. The client computer then executes the firmware update program in the PXE environment. The firmware update program transmits a request to the server computer for the firmware image file to be used to update the operational firmware, receives the firmware image from the server computer, and updates the operational firmware of the client computer utilizing the received firmware image.

Use of off-motherboard resources in a computer system
ActiveUS7058797B2Save spaceShorten the timeDigital computer detailsData resettingElectricityComputerized system
A system uses a protocol stack on a card external to a motherboard in a target computer system. A processor on the motherboard is able to make use of the external protocol stack during boot-up of the computer, or at any other time, so that it is not necessary to load the protocol stack into the motherboard's memory. This saves time, memory, and disk space and permits an external, managing, computer system to communicate with a computer just after power-up without loading and configuring a protocol stack so that the managing computer system can control the boot-up of the target computer system. The extra memory saved, especially, is important in running many MS-DOS applications, such as firmware flash utilities. A preferred embodiment of the invention uses a UDP / Internet Protocol (UDP / IP) stack resident in a Preboot Execution Environment (PXE) on, e.g, a network card. The approach described herein can be applied to other utilities, protocol stacks or resources (hardware and software) on other cards.

Secure switching for downloading network boots
A method and system for managing a secure network boot of a secondary server (server blade). The server blade sends a request, via an Ethernet switch, for a boot program to multiple Dynamic Host Configuration Protocol (DHCP) servers. One of the DHCP servers responds with an address of at least one Pre-boot Execution Environment (PXE) server that can upload a boot program to the server blade. Only if the responding DHCP server is on a list of known trusted DHCP servers will the Ethernet switch allow the server blade to receive the response from the responding DHCP server, thus allowing the download of a boot program from a PXE server.

Method, apparatus, and program for server based network computer load balancing across multiple boot servers
A method, system, and program is provided to redirect a client computer to an appropriate boot server after it has been directed to any initial boot server by preboot execution environment (PXE) or similar services. An apparatus includes a data file containing a set of addresses of managed boot servers in any syntax and a program file containing a network bootstrap program (NBP) that interprets the syntax of the data file. These files are placed on every initial boot server. The NBP requests a file from the initial boot server whose name is identified with the client computer. The initial boot server will not return that file if it is not an appropriate server for booting the client. In that case, the NBP requests the data file containing the boot server addresses. The NBP then polls each of those boot servers by requesting the client's unique file. A boot server that returns the file is an appropriate boot server for the client computer. The data file containing boot server addresses is changed to reflect current boot server load balancing requirements without involving the configuration or affecting the availability of PXE or similar services.

InactiveUS7363374B2Increase dependenceMinimum quality of serviceMultiprogramming arrangementsMultiple digital computer combinationsQuality of serviceClient-side
A method and system are presented for facilitating a PXE-compliant (Preboot Execution Environment) remote boot process between clients and multiple available servers on a network. Each server device can respond to a PXE-extended DHCP (Dynamic Host Configuration Protocol) Request message from any client device on the network. Each client can receive responses from the alternate servers, select a server from one of those responses, and be directed by that response to complete the remote boot process from the same server. Each server also employs a self-throttling process to prevent the server from responding to new PXE-extended DHCP request messages from additional clients while the server has insufficient resources to remote boot additional clients with the required quality of service. This automatically redirects those additional clients to other servers that can provide the required quality of service without affecting the remote boot of clients already being serviced by the server.

A method and a system are presented for facilitating a PXE-compliant (Preboot Execution Environment) remote boot process between clients and multiple servers. All clients are initially directed to the address of the central boot server when they initially request remote boot service. The central boot server returns the same small initial bootstrap program to every client, which is then executed by the client's embedded boot program. The received initial bootstrap program contains only enough logic to have the client request and receive a list of alternate boot server addresses. The list may be ordered to present to the client a series of best-available boot servers, or the client may search the list to determine an address of an alternate boot server that can efficiently continue the remote boot process. The client selects a boot server from the list and requests the next program from the selected boot server.
