Abstract
A system for enabling remote console redirection on a computer system having a remote monitor connector circuit located on a different computer bus than a local monitor connector circuit. In one example, a remote monitor connector circuit located on a PCI computer bus generates system management interrupts (SMIs) via an interrupt controller to a system processor of a computer system such as a server. In response to a SMI, the system processor invokes an interrupt handler to determine the source of the interrupt. In response to determining that the SMI was generated by the remote monitor connector circuit, the system processor places the video data being provided to a local monitor connector circuit (such as a graphics accelerator conforming to the Accelerated Graphics Port interface standard) into a shared memory location accessible by both the system processor and the remote monitor connector circuit. The remote monitor connector circuit provides the video data to a remote monitor via e.g. a telephone network for display on the remote monitor. The remote monitor connector circuit generates the SMIs periodically during a startup routine until a graphical mode operating system boots up.
