得到真实物理MAC地址--注意是真实的

[luoming]

现在有工具可以通过直接修改注册表或在WINDOWS中指定MAC地址从而达到修改MAC地址的功能，WINDOWS通常是通过读取注册表获得MAC地址，那么我现在想通过软件代码，即使WINDOWS已逻辑修改了MAC地址，通过代码都能读出真实的MAC地址


求此读取真实MAC地址的代码。

这好像也是得到注册表中的MAC吧，先试试吧，这段代码我用过

大家都不会???????????????

用這個試試, 真實的, 不知能否:
uses NB30;

function GetMACAdress: string;
var
NCB: PNCB;
Adapter: PAdapterStatus;

URetCode: PChar;
RetCode: char;
I: integer;
Lenum: PlanaEnum;
_SystemID: string;
TMPSTR: string;
begin
Result := '';
_SystemID := '';
Getmem(NCB, SizeOf(TNCB));
Fillchar(NCB^, SizeOf(TNCB), 0);

Getmem(Lenum, SizeOf(TLanaEnum));
Fillchar(Lenum^, SizeOf(TLanaEnum), 0);

Getmem(Adapter, SizeOf(TAdapterStatus));
Fillchar(Adapter^, SizeOf(TAdapterStatus), 0);

Lenum.Length := chr(0);
NCB.ncb_command := chr(NCBENUM);
NCB.ncb_buffer := Pointer(Lenum);
NCB.ncb_length := SizeOf(Lenum);
RetCode := Netbios(NCB);

i := 0;
repeat
Fillchar(NCB^, SizeOf(TNCB), 0);
Ncb.ncb_command := chr(NCBRESET);
Ncb.ncb_lana_num := lenum.lana[I];
RetCode := Netbios(Ncb);

Fillchar(NCB^, SizeOf(TNCB), 0);
Ncb.ncb_command := chr(NCBASTAT);
Ncb.ncb_lana_num := lenum.lana[I];
// Must be 16
Ncb.ncb_callname := '* ';

Ncb.ncb_buffer := Pointer(Adapter);

Ncb.ncb_length := SizeOf(TAdapterStatus);
RetCode := Netbios(Ncb);
//---- calc _systemId from mac-address[2-5] XOR mac-address[1]...
if (RetCode = chr(0)) or (RetCode = chr(6)) then
begin
_SystemId := IntToHex(Ord(Adapter.adapter_address[0]), 2) + '-' +
IntToHex(Ord(Adapter.adapter_address[1]), 2) + '-' +
IntToHex(Ord(Adapter.adapter_address[2]), 2) + '-' +
IntToHex(Ord(Adapter.adapter_address[3]), 2) + '-' +
IntToHex(Ord(Adapter.adapter_address[4]), 2) + '-' +
IntToHex(Ord(Adapter.adapter_address[5]), 2);
end;
Inc(i);
until (I >= Ord(Lenum.Length)) or (_SystemID <> '00-00-00-00-00-00');
FreeMem(NCB);
FreeMem(Adapter);
FreeMem(Lenum);
GetMacAdress := _SystemID;
end;

大哥啊，这个不行的

要求精度那么高的话 我看就能用汇编了！
