Нуждаюсь в информации о написании програмы, которая бы издавала бы какую-то заданую мелодию, с помощью динамика.
Вот нашел текст проги, которая издает новогоднию мелодию, только вот вьехать в неё никак не могу

ПС. Ламер я в асемблере.

что именно не ясно?

Вот - не мелодия, конечно, но спикер орёт :

.model small
.code
start:
mov al,255;ставим...
out 43h,al;...таймер.
mov ax,19000;часто-
out 42h,al;та
in AL,61h;получаем состояние динамика
or AL,3;если 2 бит 0 - то динамик выключен => надо включить
out 61h,AL;включаем
jmp start;...а теперь повтор
mov ax, 4ch
int 21h
end start
