Does anyone know something about these functions..?? According to my "BIOS Interface Technical Reference" the following BIOS interrupts exist : 02H : NMI 05H : print screen 08H : system timer 09H : keyboard 10H : video 11H : equipment determination 12H : memory size determination 13H : diskette/fixed disk 14H : asynchronous communication 15H : system services 16H : keyboard 17H : printer 19H : bootstrap loader 1AH : real time clock services Is this what you were asking for ?
