I'm trying to convert this PAS code into a C++ unit but I am not having any 
luck with the ASM code - it won't compile as is (although the PAS file 
does).

Can someone please help with the ASM translation.  I know I could just use 
the .PAS file but I want to learn something along the way.


TRegisters = record
  EAX,
  EBX,
  ECX,
  EDX: Cardinal;
end;

procedure GetCPUID(Param: Cardinal; var Registers: TRegisters);
asm
  PUSH    EBX                         {save affected registers}
  PUSH    EDI
  MOV     EDI, Registers
  XOR     EBX, EBX                    {clear EBX register}
  XOR     ECX, ECX                    {clear ECX register}
  XOR     EDX, EDX                    {clear EDX register}
  DB $0F, $A2                         {CPUID opcode}
  MOV     TRegisters(EDI).&EAX, EAX   {save EAX register}
  MOV     TRegisters(EDI).&EBX, EBX   {save EBX register}
  MOV     TRegisters(EDI).&ECX, ECX   {save ECX register}
  MOV     TRegisters(EDI).&EDX, EDX   {save EDX register}
  POP     EDI                         {restore registers}
  POP     EBX
end;
