Abstract
Embodiments of the claimed invention include a computing device having a host processor for executing a firmware environment and a manageability controller. The firmware environment reserves a frame buffer in main memory and loads a graphics protocol driver to provide the frame buffer to an operating system of the computing device. The operating system renders graphical images to the frame buffer using a graphics driver. The manageability controller reads the graphical image from the frame buffer and may transmit the graphical image to a remote computing device. In response to a fatal error of the computing device, the manageability controller may store the graphical image to a non-volatile storage device. The host processor may assert a host reset signal in response to the fatal error, and the manageability controller may send an acknowledgment to the host processor after storing the graphical image. Other embodiments are described and claimed.
