请问各位大虾如何获取硬盘序列号啊！ (50分)

问题同上，
哪位大虾有此函数或者实例，还请赐教。

怎么不能贴图？

type
MIDPtr = ^MIDRec;
MIDRec = Record
InfoLevel: word;
SerialNum: LongInt;
VolLabel: Packed Array [0..10] of Char;
FileSysType: Packed Array [0..7] of Char;
end;

function GetDriveSerialNum(MID: MIDPtr
drive: Word): Boolean
assembler;
asm
push DS { Just for safety, I dont think its really needed }
mov ax,440Dh { Function Get Media ID }
mov bx,drive { drive no (0-Default, 1-A ...) }
mov cx,0866h { category and minor code }
lds dx,MID { Load pointeraddr. }
call DOS3Call { Supposed to be faster than INT 21H }
jc @@err
mov al,1 { No carry so return TRUE }
jmp @@ok
@@err:
mov al,0 { Carry set so return FALSE }
@@ok:
pop DS { Restore DS, were not supposed to change it }
end;

procedure TForm1.NrBtnClick(Sender: TObject);
var
Info: MIDRec;
begin
Info.InfoLevel:=0
{ Information Level }
If GetDriveSerialNum(@Info,0) then { Do something with it... }
ListBox.Items.Add(IntToStr(Info.SerialNum)+' '+Info.VolLabel);
end;

谢谢大虾，我试试先。

编译不过去啊！

有点问题啊，
lds dx,MID
call DOS3Call
两个错误，一，lds dx,MID ：operand size mismatch
二，call DOS3Call: undeclared identifier:'dos3call'
