Evo nasao sam ovo, samo sta tebam da uradim da dobijem tekst MAC adrese
npr u Edit ili Memo komponentu

uses
NB30;

function GetAdapterInfo(Lana: Char): String;
var

NCB: TNCB;
begin
FillChar(NCB, SizeOf(NCB), 0);
NCB.ncb_command := Char(NCBRESET);
NCB.ncb_lana_num := Lana;
if Netbios(@NCB) <> Char(NRC_GOODRET) then
begin
Result := 'mac not found';
Exit;
end;

NCB.ncb_callname := '*';

NCB.ncb_length := SizeOf(Adapter);
if Netbios(@NCB) <> Char(NRC_GOODRET) then
begin
Result := 'mac not found';
Exit;
end;
Result :=
IntToHex(Byte(Adapter.adapter_address[0]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[1]), 2) + '-' +

IntToHex(Byte(Adapter.adapter_address[3]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[4]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[5]), 2);
end;

function GetMACAddress: string;
var
AdapterList: TLanaEnum;
NCB: TNCB;
begin
FillChar(NCB, SizeOf(NCB), 0);
NCB.ncb_command := Char(NCBENUM);
NCB.ncb_buffer := @AdapterList;
NCB.ncb_length := SizeOf(AdapterList);
Netbios(@NCB);
if Byte(AdapterList.length) > 0 then
Result := GetAdapterInfo(AdapterList.lana[0])
else
Result := 'mac not found';
end;

Pa verovatno da pozoves:

Evo ti u attachment-u demo... isprobaj

JCL ima vise funkcija za citanje informacija o sistemu. Medju njima i ovu.

Ne razumjem sta je JCL , jel neko zna jos neku proceduru za citanje podataka sa
hardvera (za HDD i Mreznu znam) npr neki broj sa maticne ploce.
