Beep without API

I was curious if using a non-API method would affect file size.

Hi There:

If your Keyboard has a speaker do a Control G or send a 7 (seven) to StdOut.
From a Dos prompt i e Command Prompt do a Control G. If you have a speaker
you should hear a beep and see a error message, otherwise just an
error message.

        print " << Kenya Time is Wrong >> ", 13, 10, 7

On Windows XP you can use bios display service :

mov         ah,00E ; TELETYPE OUTPUT
mov         al,7      ; CHAR CODE
int            10h      ; BIOS DISPLAY SERVICE
int            20h      ; EXIT (DIRTY)

Resulting BEEP.COM executable is equal to QWORD in size:

B4 0E B0 07 CD 10 CD 20

Using port io is another way of doing it.
