System for support of remote console by emulation of local console with multipath data flow structure

摘要

Numerous shortcomings exist in prior generation adapter cards for supporting remote consoles for multipartition computer systems. Emulation using memory in the adapter card supports some remote functions so that they appear to be resident on the host computer system to each partition. Additionally, the host computer system memory can be used in one mode to support the emulation of extended mode video console support functions. Scoreboarding and hardware compression are used to limit the volume of data required to be updated to support the emulation.
