Detailed Description

The ACPI root system description pointer (RSDP).

This structre must be located by the system at boot time. It contains some validation information and a pointer to the root system description table, from which all other ACPI information is gleaned.

Public Member Functions
RootSystemDescriptionTable *	rsdtAddress () const
	Gets the address of the Root System Descriptor Table.
Static Public Member Functions
static const RootSystemDescriptionPointer *	locateRSDT ()
	Locates the RSDP is there is one to be located.
