4.2.4.6ACPI

32430C

Initialization

4.2.4.6ACPI

Location:

9C00h or other normal ACPI location.

Description: NA

Initialization: ACPI VSM

4.2.4.7Power Management Logic

Location:

9D00h put on the end of ACPI.

Description: NA

Initialization: VSA technology and ACPI VSM as needed.

4.2.4.8Flash Interface

Location:	4 LBARs for 4 Flash devices
Description:	NA
Initialization:	The default values for the LBARs are located in BDCFG.INC in the platform directory, but can be

	changed at Boot via setup. The Flash interface is configured in the code at ChipsetFlashSetup in
	CHIPSET.ASM based on the corresponding NVRAM values.

4.2.4.9Other Legacy DD Initialization

Location:	Default legacy definitions.
Description:	Initialize COM ports, LPT ports, RTC.
Initialization:	These devices are initialized in the same fashion as with a normal SuperI/O and CS5535. Any MSR reg-
	ister settings will be done in chipset individualization. GeodeROM can handle multiple devices and loca-
	tions by design.
