Methods and systems to support XML-based security and key management services in a pre-boot execution environment. During pre-boot, XML console in and console out interfaces are loaded, and corresponding API's are published to enable use of the interfaces by various firmware and software components. A network stack is set up to enable XML content received at the network interface to be forwarded to the XML console in interface and XML content provided at the XML content out interface to be sent out via the network interface. Security operations may then be performed to authenticate a client system hosting the XML interfaces, to authenticate remote servers to which the client system may communicate with, and to validate boot images provided to the computer system. Key management services are also supported.

Embodiments of the invention address deficiencies of the art in respect to PXE processing and provide a novel and non-obvious method, system and computer program product for selective PXE subnet filtering. In an embodiment of the invention, a PXE server subnet filtering method can be provided. The method can include selectively referring a PXE client to different boot logic depending upon at least a portion of a network assigned address for the PXE client. In this regard, selectively referring a PXE client to different boot logic depending upon at least a portion of a network assigned address for the PXE client can include selectively referring a PXE client to a different boot image notification layer (BINL) service providing a different filename for a different network bootstrap program depending upon at least a portion of an Internet protocol (IP) assigned address for the PXE client by a network resident dynamic host control protocol (DHCP) server in response to a previous DHCP request provided by the PXE client.

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.

One or more designated VEE(s) provide security services to each of the VEEs based on the needs of the remote users of the particular VEEs. The security services provided by the designated VEE can be firewall services, spam filtering and anti-virus protection. The security services are controlled and administered by each of the VEEs requesting a particular service via control means of the designated VEE(s).

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.

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 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.
