Core Logic Module - SMI Status and ACPI Registers - Function 1 32581C
0 EXT_SMI0 SMI Enable. When this bit is asserted, allow EXT_SMI0 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 16 (RC) and 8 (RO).
Offset 28h-4Fh Not Used Reset Value: 00h
Offset
50h-FFh The I/O mapped registers located here (F1BAR0+I/O Offset 50h-FFh) can also be accessed at F0 Index 50h-FFh. The pre-
ferred method is to program these registers through the F0 register space. Refer to Table 6-29 "F0: PCI Header/Bridge Con-
figuration Registers for GPIO and LPC Support" on page 188 for more information about these registers.
