摘要:
A cooling fan, system and method for controlling cooling fans in a personal computer. A unique series of sensing points is placed on a rotating hub of a cooling fan in order to uniquely identify the particular type of cooling fan. A tachometer sensor mounted in the cooling fan detects the unique series of sensing points as the cooling fan rotates and generates a sequence of pulses corresponding to the detected sending points. This generated pulse signal may be transmitted by the sensor to the fan control code. The fan control code may determine a particular type of cooling fan that the cooling fan is based on the generated pulse signal. Once the fan control code determines the particular type of cooling fan that the cooling fan is, the fan control code uses particular control parameters set for that particular type of cooling fan to control the cooling fan so that it operates optimally.

Methods, systems, and media are disclosed for managing a remote client of a computer system. One example embodiment includes transmitting a modified wake-on LAN (“WOL”) packet to a network receive buffer on the remote client, wherein the modified WOL packet comprises additional data, such as executable code or functions. Further, the example embodiment includes retrieving, by BIOS associated with the remote client, of the modified WOL packet from the network receive buffer, storing, by the BIOS, storing of the additional data in memory associated with the network receive buffer, and retrieving, by BIOS associated with the remote client, of the additional data from the memory. Further still, the example embodiment includes processing of the additional data, which may occur by an application stored on the PARTIES partition, wherein the parsed, additional data is interpreted and executed by the application.

Systems and arrangements for remotely selecting a bootable image via a WOL packet for a wake-on-LAN (WOL) capable computer are contemplated. Server-side embodiments include hardware and/or software for determining a client to be managed, determining whether the client is active on the network, and transmitting a WOL packet having a vector, or operating system partition identification (OSPID), to describe a bootable image accessible by the WOL capable computer. Some embodiments may include an OSPID that points to a secure bootable image such as a bootable image on a hard drive, a compact disk (CD) connected to the computer, or other local resource. Client-side embodiments may receive the WOL packet at, for instance, a network interface card (NIC), recognize that the WOL packet includes an OSPID that describes the bootable image to boot, and implement an alternative boot sequence to boot from that bootable image.
摘要:
A method, computer program product and system for detecting modifications to code placed in memory by the POST BIOS during a POST operation. The POST BIOS may measure the legacy BIOS code and the code supporting the legacy BIOS during the POST operation and storing that measurement in a secure location. After the system runs in an activated state, the system may enter a sleep state after a period of inactivity. After the system receives an awakening event, the boot block code may measure the legacy BIOS code and the code supporting the legacy BIOS code stored in memory. The boot block code may compare the measurement with the value stored in the secure location by the POST BIOS. If the measurement does not equal the value stored in the secure location, then modification of either the legacy BIOS code and/or code supporting the legacy BIOS code is detected.
摘要翻译:一种用于在POST操作期间检测由POST BIOS在存储器中对代码的修改的方法,计算机程序产品和系统。 POST BIOS可以在POST操作期间测量传统BIOS代码和支持传统BIOS的代码,并将该测量存储在安全位置。 在系统运行在激活状态之后,系统可以在一段不活动状态之后进入休眠状态。 在系统收到唤醒事件之后,引导块代码可以测量传统BIOS代码和支持存储在存储器中的旧BIOS代码的代码。 引导块代码可以将测量与POST BIOS中存储在安全位置中的值进行比较。 如果测量值不等于存储在安全位置的值,则检测到传统BIOS代码和/或支持传统BIOS代码的代码的修改。
摘要:
An apparatus, system, and method are disclosed for making a motion based business decision. A motion module senses a component of motion such as acceleration or a derivative of acceleration. A log module calculates a motion summary from the motion component and stores the motion summary in a memory module. An analysis module receives the motion summary and makes a business decision based on the motion summary.
