SMM Enhancement
Prior to the advent of the Pentium® Pro processor, the base address of the area of memory assigned to System Management Mode (SMM) had a default value of 30000h assigned. While it could be reprogrammed on the earlier IA32 processors, the newly assigned address had to be aligned on an address that was evenly divisible by 32K. Starting with the Pentium® Pro, this constraint was eliminated. See “Relocating the SM RAM Base Address” on page 1495 for more information.
