procedure ishtt;
var
  _edx : integer;
begin
  asm
    push ebx
    mov eax, 1
    cpuid
    mov _edx, edx
    pop ebx
  end;
  if ( _edx and $01000000 ) = $01000000 then
  MessageBox(0, 'Bit 28 zapalony - HTT obs ugiwane.', 'CPUID:', 0)
  else MessageBox(0, 'Bit 28 zgaszony - HTT NIE obs ugiwane.',
'CPUID:', 0);
end;

Pokazuje,  e HTT jest obs ugiwane...
