用delphi获取主板BIOS信息2009-01-301、读取主板序列号2、AWard Bios密码读取3、读取BIOS信息4、获取BIOS日期信息=========================================1、读取主板序列号uses SHA1, Base64;
function GetHashedBiosInfo: string;
var
SHA1Context: TSHA1Context;
SHA1Digest: TSHA1Digest;
begin
// Get the BIOS data
SetString(Result, PChar(Ptr($F0000)), $10000);
// Hash the string
SHA1Init(SHA1Context);
SHA1Update(SHA1Context, PChar(Result), Length(Result));
SHA1Final(SHA1Context, SHA1Digest);
SetString(Result, PChar(@SHA1Digest), sizeof(SHA1Digest));
// Return the hash string encoded in printable characters
Result := B64Encode(Result);
end;
function GetBiosInfoAsText: string;
var
p, q: pchar;
begin
q := nil;
p := PChar(Ptr($FE000));
repeat
if q <> nil then begin
if not (p^ in [#10, #13, #32..#126, #169, #184]) then begin
if (p^ = #0) and (p - q >= 8) then begin
Result := Result + TrimRight(String(q)) + #13#10;
end;
q := nil;
end;
end else
if p^ in [#33..#126, #169, #184] then
q := p;
inc(p);
until p > PChar(Ptr($FFFFF));
Result := TrimRight(Result);
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
Memo1.Lines.Text := GetBiosInfoAsText;
end;

2、AWard Bios密码读取(应该是jingtao的文章,但是ID没有记录)Unit AwardBiosPas;
