Dzień dobry,
Jak w temacie. Czy da się w systemie DOS wyłączyć niepotrzebne procesy działające w przerywaniach DOSa?
Interrupt Value Function
0 CPU - Divide by zero (exception interrupt)
1 CPU - Single step
2 CPU - Non-maskable interrupt (NMI)
3 CPU - Break point instruction
4 CPU - Overflow Trap
5 BIOS - Print screen
6 CPU - Invalid op-code
7 CPU - Math coprocessor not present
8 System timer interrupt (IRQ 0)
9 Keyboard data ready (IRQ 1)
A Reserved (IRQ 2) cascade from slave interrupt controller
B, C Hardware interrupt for serial communication (IRQ 3, IRQ 4)
D Parallel port hardware interrupt (IRQ 5, LPT 2)
E Diskette controller hardware interrupt (IRQ 6)
F Printer hardware interrupt (IRQ 7, LPT 1)
10 BIOS - Software interrupt to use video
11 BIOS - Equipment check call
12 BIOS - Memory check call
13 BIOS - Software interrupt to use hard drive
14 BIOS - Software interrupt to use serial port
15 Not used
16 BIOS - Keyboard software interrupt
17 BIOS ? Printer software interrupt
