ABSTRACT:
In some embodiments, the invention involves speeding boot up of a platform by initializing the video card early on in the boot process. In an embodiment, processor cache memory is to be used as cache as RAM (CAR). Video graphics adapter (VGA) card initialization uses the CAR instead of system RAM to perform initialization. A portion of the firmware code, interrupt vector tables and handlers are mirrored in the CAR, from flash memory to mimic the behavior of system RAM during the video initialization. VGA initialization may occur before system RAM has initialized to enable early visual feedback to a user. Other embodiments are described and claimed.
