Abstract: A memory module that comprises a plurality of memory circuits, at least one serial presence detect (SPD) memory circuit, and a plurality of data lines that transfer data to and from the plurality of memory circuits. The memory module may further comprise a testing logic that utilizes data stored in the SPD memory circuit to inject a memory error into one or more of the plurality data lines.

Abstract: A computer system powers off upon operation of a power switch when the power switch is enabled. A switch mask enables and disables the power switch without intervention by an operating system of the computer system.

Abstract: A computer system having integrated remote console functionality. Cycles intended for a video graphics controller are snooped to acquire the video data or control information contained in the cycle. Analysis is performed on the video data to detect sequential or repetitive operations. The video data is encoded into higher level primitives, if possible. The video data and primitives are held in a first-in-first-out (FIFO) memory until the FIFO reaches a critical level, or a staleness timer times out. Special firmware executed in system management mode reads the FIFO and converts the video data and primitives into conventional ASCII text or the required format. The firmware also maintains a copy of the video frame buffer to further encode the video data, if possible. The firmware then transmits the conventional ASCII text via a modem to a user stationed at a remote computer system.
