Processor Data Sheet
SMM State-Save Area
When the processor acknowledges an SMI# interrupt by
asserting SMIACT#, it saves its state in a 512-byte SMM
state-save area shown in Table 34. The save begins at the top of
the SMM memory area (SMM base address + FFFFh) and fills
down to SMM base address + FE00h.
Table 34 shows the offsets in the SMM state-save area relative
to the SMM base address. The SMM service routine can alter
any of the read/write values in the state-save area.
