Abstract

A computer system includes a bus, remote console logic, a remote server management device, and an interrupt routing switch. The bus has a first interrupt line. The remote console logic has a second interrupt line and is coupled to the bus. The remote console logic is adapted to monitor video transactions present on the bus. The video transactions include video data. The remote console logic is further adapted to store the video data and provide an interrupt signal on the second interrupt line if the amount of stored video data reaches a predetermined threshold. The remote server management device is coupled to the bus and the first interrupt line. The interrupt routing switch is coupled to the first interrupt line and the second interrupt line and adapted to couple the second interrupt line to the first interrupt line. A method for capturing video transactions includes coupling a first interrupt line of a buffer to a shared interrupt line of a bus. Video transactions occurring on the bus are snooped. The video transactions include video data. At least a portion of the video data is stored in the buffer. An interrupt signal is generated on the first interrupt line when the amount of data in the buffer reaches a predetermined threshold. The interrupt signal is received on the shared interrupt line in a remote server management device having memory. At least a portion of the video data is stored in the memory in response to the interrupt signal.

Claims
