G2, System Soft Off
Power is removed from most of system components, Suspend Well logic in ICH10, SIO.
G3, Mechanical off
Kinds of computer state that system entered and only left mechanical means. It is implied by the entry of this off state
through a mechanical means that the no electrical current is running through the circuitry and it can be worked on without
damaging the hardware or endangering the service personnel. No hardware context is retained. Except for the real time clock,
power consumption is zero. No power source is attached to the system (AC or battery). Pushing the Power button will be no
function in state at all.
Resume events are: Power Button
Query System Address Map
INT 15H, E820H - Query System Address Map
This call can be used in real mode only.
This call returns a memory map of the entire installed RAM, and of physical memory ranges reserved by the BIOS. Making
successive calls to this API, each returning one run of physical address information, returns the address map. Each run has a
type that dictates how this run of physical address range is to be treated by the operating system.
If the information returned from E820 in some way differs from INT-15 88 or INT-15 E801, the information returned from
E820 supersedes the information returned from INT-15 88 or INT-15 E801. This replacement allows the BIOS to return any
information that it requires from INT-15 88 or INT-15 E801 for compatibility reasons. For compatibility reasons, if E820
returns any AddressRangeACPI or AddressRangeNVS memory ranges below 16Mb, the INT-15 88 and INT-15 E801
functions must return the top of memory below the AddressRangeACPI and AddressRangeNVS memory ranges.
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 that the BIOS fills in.
ECX Buffer Size
The length in bytes of the structure passed to the BIOS. The BIOS fills in the
number of bytes of the structure indicated in the ECX register, maximum, or
whatever amount of the structure the BIOS implements. The minimum size that
must be supported by both the BIOS and the caller is 20 bytes. Future
implementations might 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.
