Abstract:
1. A baseboard management controller for monitoring a host, comprising: a baseboard management control module comprising: a memory controller being connected with the microprocessor bus for controlling accesses of program codes and data; and a video graphic array (VGA) module comprising: wherein when the first address signal points to an aperture allocated in a VGA section of a memory space of the host, the decoder transfers the transaction signal to the mapping circuit; wherein when the first address signal points to a frame buffer address region allocated in the VGA section, the decoder transfers the transaction signal to the memory controller; wherein when the first address signal points to a video controller address region allocated in the VGA section, the decoder transfers the transaction signal to the video controller; wherein the aperture does not overlap with the frame buffer address region and the video controller address region in the VGA section; and wherein the predetermined second address signal points to a target block in a memory space of the microprocessor.
