Figure 1 shows the default map of the SMM memory area. It
consists of a 64-Kbyte area, between 0003_0000h and
0003_FFFFh, of which the top 32 Kbytes (0003_8000h to
0003_FFFFh) must be populated with RAM. The default
code-segment (CS) base address for the area—called the SMM
base address — is at 0003_0000h. The top 512 bytes
(0003_FE00h to 0003_FFFFh) contain a fill-down SMM
state-save area. The default entry point for the SMM service
routine is 0003_8000h.
