Patent ID: 7987348

Claim:
A system for early video subsystem initialization, comprising: a processor coupled to cache memory; system random access memory (RAM) communicatively coupled to the processor; a firmware hub coupled to the processor comprising firmware memory having firmware code comprising a basic system input output system (BIOS) stored thereon; a video console communicatively coupled to the processor via a video subsystem component; a first portion of the cache memory to be used as cache as RAM (CAR) and store a first portion of the BIOS, a second portion of BIOS code comprising an interrupt vector table and interrupt handlers for communication to the video subsystem component, and option-ROM initialization code retrieved from the video subsystem component, wherein during boot up process, the video subsystem component is to execute the initialization code from the cache memory before system RAM has been initialized, and wherein the interrupt vector table includes a dummy handler to enable operation of the video subsystem prior to initialization of system RAM.
