; Input:
;
; EAX Function Code E820h
; EBX Continuation Contains the "continuation value" to get the
; next run of physical memory. This is the
; value returned by a previous call to this
; routine. If this is the first call, EBX
; must contain zero.
; ES:DI Buffer Pointer Pointer to an Address Range Descriptor
; structure which the BIOS is to fill in.
; ECX Buffer Size The length in bytes of the structure passed
; to the BIOS. The BIOS will fill in at most
; ECX bytes of the structure or however much
; of the structure the BIOS implements. The
; minimum size which must be supported by both
; the BIOS and the caller is 20 bytes. Future
; implementations may extend this structure.
; EDX Signature 'SMAP' - Used by the BIOS to verify the
; caller is requesting the system map
; information to be returned in ES:DI.
;
; Output:
;
; CF Carry Flag Non-Carry - indicates no error
; EAX Signature 'SMAP' - Signature to verify correct BIOS
; revision.
; ES:DI Buffer Pointer Returned Address Range Descriptor pointer.
; Same value as on input.
; ECX Buffer Size Number of bytes returned by the BIOS in the
; address range descriptor. The minimum size
; structure returned by the BIOS is 20 bytes.
; EBX Continuation Contains the continuation value to get the
; next address descriptor. The actual
; significance of the continuation value is up
; to the discretion of the BIOS. The caller
; must pass the continuation value unchanged
; as input to the next iteration of the E820
; call in order to get the next Address Range
; Descriptor. A return value of zero means that
; this is the last descriptor

; The BaseAddrLow and BaseAddrHigh together are the 64 bit BaseAddress of this range.
; The BaseAddress is the physical address of the start of the range being specified.
;
; The LengthLow and LengthHigh together are the 64 bit Length of this range.
; The Length is the physical contiguous length in bytes of a range being specified.
;
; The Type field describes the usage of the described address range as defined in the table below.
; Value Pneumonic Description
; 1 AddressRangeMemory This run is available RAM usable by the operating system.
; 2 AddressRangeReserved This run of addresses is in use or reserved by the system, and must not be used by the operating system.
; Other Undefined Undefined - Reserved for future use.
