    摘要: Methods and systems for performing network port authentication without requiring any operating system (OS) complicity are disclosed. Under one method, port authentication instructions are loaded into a protected memory space during a pre-boot of a supplicant system. In response to a port authentication request, the supplicant system's processor is switched to a hidden execution mode and executes the port authentication instructions to authenticate a network port hosted by an authenticator system to which the supplicant system is linked. One authentication process employs an authentication server that authenticates the supplicant via one of various authentication schemes, including an access challenge. Port authentication may also be performed via an out-of-band base management controller that operates independently from an operating system running on the supplicant.

    摘要: A plurality of servers arranged in a cluster, such as a plurality of blade servers, may communicate with a network over a first communication path. The servers may also communicate with each other over another communication path such as an out-of-band channel. Using the out-of-band channel, a server that is having a communication or a software failure may communication with other blade servers using the out-of-band channel. The other blade servers may act as a proxy for the server with a problem, enabling the proxy to communicate on behalf of the server having a communication problem. As a result, useful computational work may be obtained in many cases from servers that would otherwise be taken off-line.

    摘要: A method and system for establishing a virtualized environment includes booting a first virtual machine monitor to establish a first virtual machine and booting a second virtual machine monitor in the first virtual machine. The first and second virtual machine monitors may be hypervisors. The method may also include directing management interrupts, such as system management interrupts and/or platform management interrupts, to the first virtual machine monitor.

    摘要: A method and system for recovery of a computing environment includes monitoring during a pre-boot phase and a runtime phase of a computing device for selection of a hot key sequence by a user and performing a recovery action in response to the selection of the hot key sequence by the user. The recovery action may be any one of a number of predetermined and/or selectable actions such as restoring system defaults, migrating memory, displaying a menu of options, setting various software flags, restarting or rebooting the computing device, and/or the like.

    摘要: A system, method, and computer-readable medium with instructions for capturing a system management interrupt instruction by trusted system management mode code running in a system. The system management interrupt instruction is dispatched to other system management mode code, which may be untrusted. In response to an attempt to access a protected resource of the system by the other system management mode code, a determination is made whether the second system management mode code is authorized to access the protected resource. If the second system management mode code is not authorized to access the protected resource, access to the protected resource by the other system management mode code is prevented. Other embodiments are described and claimed.
